What is BOINC?
BOINC is an open source grid software package. BOINC stands for Berkeley Open Infrastructure for Network Computing. It has been developed under a National Science Foundation grant. The software provides server side components that allow the management of a science project. It also includes client software that runs on a variety of platforms, including Linux. More information about BOINC may be found at http://boinc.berkeley.edu/.

I have a platform that isn't supported by World Community Grid. Could I get a copy of the research application code and compile it myself?
No. The code has to remain in the control of the World Community Grid support team. Even the slightest change in the code, including using a different compiler, could render the research results useless. In addition, the license agreement that we have with the researchers for their code stipulate that only the World Community Grid support team can touch the source code. The source code usually differs slightly from potential public versions of the same code due to changes made for use with the specific grid project. Furthermore, we typically run many tests to make certain there are no problems on a given platform.

What was the difference between run time reported by the United Devices version and the BOINC version?
It is important to note, that the time reported to the server doesn't mean that the UD version was doing more work then the BOINC version. The UD version simply overcounted the actual time that was contributed to the project. In fact, the BOINC version actually contributes more time to the project because it is able to take advantage of multi-core processors or multi-processory systems. The UD version could only use one core or processor. The BOINC version will start up a science application on each core or processor and thus be able to get two or more times the work done.

How is "run time" calculated?
"Run time" is simply a measurement of how long a volunteer's device spends running World Community Grid tasks. You accumulate run time for running tasks on your device's GPU, CPU, or both.

  • If you contribute GPU time, the run time is the actual elapsed time in which the World Community Grid task executes on the GPU. In other words, if the task starts at 10:15am and finishes at 10:19am, you accumulate 4 minutes of run time.

  • If you contribute CPU time, the picture is a bit more complicated because CPUs can prioritize different tasks and have multiple cores. Only the time a CPU spends actually executing a World Community Grid task counts toward your run time. As an example, if a quad-core computer runs a World Community Grid task on each core at 75% throttle from 10:15am to 10:19am, then each core will accumulate 3 minutes of run time (75% of 4 minutes). Across all 4 cores, the total run time would therefore be 4 x 3 minutes = 12 minutes.

    How much hard drive space does the software take on my computer?
    The software itself will take less than 50 MB of hard drive space or your computer. The different projects that run on the World Community Grid, however, have different system requirements for running on your computer. To find out if your computer meets those requirements, go here.

    Why does World Community Grid require version 5.4 or higher of the BOINC client?
    World Community Grid requires version 5.4 of the BOINC client because we have configured the system to communicate with the BOINC client over SSL. Only version 5.4 and higher of the BOINC client are able to utilize SSL. SSL is a technology that encrypts all communication between the client and the server. This provides greater security for our members.

    If you attempt to use an older version of the BOINC client, then you will see an error in the BOINC client log file.

    Return to Top 

    Are there any specific system requirements for running World Community Grid on Android?
    Overall, World Community Grid only requires that the phone be running Android 2.3.3 or higher, but each research project has its own requirements for storage and memory usage. More details are available here.
    Return to Top 

    Will this reduce battery life?
    By default, the Android BOINC application is only active when your device is plugged into a power source (AC or USB) and your battery is charged 90% or more. Using the application will not significantly reduce your battery life or your recharge time. If you wish, you can override these default power use settings and customize how World Community Grid runs on your device.
    Return to Top 

    Will it use up my cellphone data plan?
    No. The Android BOINC application only transfers data (downloads tasks or uploads results) when your device is connected to a WiFi network. You can override these default settings in device preferences.
    Return to Top 

    Will work unit deadlines be different for Android devices?
    No. For now, all work units for projects that run on Android have been made smaller for all platforms, and are small enough to compute on an Android device in a reasonable amount of time. There are future plans to size work units dynamically based on the device a task is being computed on.

    How can I limit when the software connects to the Internet?
    There are two ways to do this:
    • On your machine, go to [Start] [Settings] [Control Panel] and double click on "Internet Options." Click on the [Connections] tab. There will be 3 radial buttons towards the bottom of the window; set them to "Never dial a connection." Because the software operates like any other Windows application and simply requests an Internet connection that Windows then provides, doing this will force Windows to ignore requests for an Internet connection. You must therefore manually initiate a connection to your ISP to connect to the Internet.
    • Enter the Device Profiles section of the site. Next click on the default profile and follow the instructions to change the execution time for your computer(s) and save. This will change the connection times for all computers under your member name.
    • To change the connection times for a particular computer under your member name. Double click on the World Community Grid, or BOINC, icon in your system tray. Select Preferences and designate your preferred connections times and select “save”.

    I have the same device listed more than once on my device list. How can I delete the duplicate device?
    The World Community Grid agent registers itself as a new device each time the software is installed. The agent does not know whether it is being installed on a device where it was previously installed or whether it is a new device altogether. If you install the software more than once on the same device, then you are likely to see two devices with the same name listed on the website. At this time it is not possible to delete the additional devices listed on the website. The Device Manager page and the Device Statistics page shows by default all of your devices that were registered within the past 7 days or that have returned a result within the past 14 days. Unused devices do not appear on this page when these time periods have passed.
    Return to Top 

    Can I set the agent not to run while I am using the device?
    Yes, you may customize the agent not to run when you are using the device. This is done by updating the device profile associated with the device where the agent is running.

    Why did my firewall just log an attempt to access my device right after I visited the World Community Grid website?
    Some users have noticed, via their software firewall, that trace-route scans apparently coming from IBM domains occur after communicating with the World Community Grid server. These are in fact normal and not someone trying to break into your machine. These are used to measure which of several paths through the Internet give the best communication performance to your machine. The servers are located in a massive hosting center, which regularly optimizes traffic between users and the servers by shifting communications among several Internet providers, depending on the destination and trace-route measurements.

    My Internet Service Provider charges me based on the amount of bandwidth I use. How can I control how much bandwidth is used for World Community Grid?
    The most recent version of the World Community Grid/BOINC Software allows you to control how much data is transferred between your computer and our servers. You can set this by doing the following:

  • Go to 'My Grid'.
  • Go to 'Device Manager'.
  • Look for the device that you want to limit, and then click on the selected profile for that device.
  • On the screen that is presented, select 'Custom Profile'.
  • Scroll down to the section that says 'Network Usage' and find the item labeled: Transfer at most: X Mbytes every Y days.

    You can use this to say that you only want World Community Grid to use at most 500MBytes of bandwidth every 7 days (which would then limit you to 2GBytes/month). Or you could put 1024MBytes every 31 days which would limit you to 1GB per month.

    How will World Community Grid software affect people who use a VPN for telecommuting?
    The software will not have any effect. The software communicates without problems with, or without, VPN Client Software. Our server site is an external internet address. The bandwidth usage is minimal and equivalent to visiting a few web pages once a week or every few days on more powerful computers.

    Why does my firewall keep asking me if I want to contact World Community Grid. Isn't it safe?
    Firewalls are not familiar with World Community Grid. Even though World Community Grid is safe, firewalls are designed to ask you to make the decision. Most firewalls will allow you to set your firewall to allow communications with World Community Grid BOINC client. Although firewalls differ, you should be able to click on your firewall icon in your system tray and set permissions to allow communications.

    Also please note, when firewall software is updated by the manufacturer, you may be required to update your permissions for World Community Grid BOINC client communications. The same is true if the World Community Grid software is updated.

    If you have a Zone Labs firewall, just click on "Yes" to continue. You may save yourself some time in the future by optionally check-marking the message "Always allow this program to access the internet" and/or check-marking the message "Remember this answer the next time I use this program."

    If you have Symantec Client Firewall, you can select "Permit Always" if/when an alert comes up so that you won't be prompted again when the World Community Grid BOINC client tries to communicate with the World Community Grid servers.

    Return to Top 

    Does the World Community Grid software work with Zone Labs and how do I configure the Firewall?
    Yes. The software initiates only outgoing connections on ports 80, 443 and 31416 to www.worldcommunitygrid.org and secure.worldcommunitygrid.org. This could be preconfigured as a safe zone. Alternatively, the boinc.exe and boincmgr.exe executables in the BOINC install directory could be configured to be permitted to perform this communication. However, if and when we update the agent software, it could need to be configured again.

    1. Double click on the Zone Labs icon in the system tray at the lower right.
    2. Click on "Firewall" at the left.
    3. Click on the "Zones" folder tab in the upper right area.
    4. Click on "Add >>" in the lower right.
    5. Choose "Host/Site".
    6. Select "Trusted" for the Zone field.
    7. Enter "secure.worldcommunitygrid.org" for the Host Name field.
    8. Enter "World Community Grid Secure" for the Description field.
    9. Click the Lookup button.
    10. Click OK.
    11. Repeat the adding of a "Host/Site" using "www.worldcommunitygrid.org" for the Host Name, and "World Community Grid WWW" for the Description.
    12. Click Apply in the lower right.
    13. Then close the window with the X in the upper right.

    Return to Top 

    Does the World Community Grid software work with Symantec Client Firewall and how do I configure the Firewall?
    Yes. The software initiates only outgoing connections on ports 80, 443 and 31416 to www.worldcommunitygrid.org and secure.worldcommunitygrid.org. This could be preconfigured as a safe zone. Alternatively, the boinc.exe and boincmgr.exe executables in the BOINC install directory could be configured to be permitted to perform this communication. However, if and when we update the agent software, it could need to be configured again.

    Configuring the Symantec Client Firewall:
    1. Double click on the Symantec Client Firewall icon in the system tray at the lower right.
    2. With "Status & Settings" selected, click on "Client Firewall".
    3. Click on the Configure button.
    4. Click on the Programs tab.
    5. Under "Manual Program Control", scroll down to "BOINC client".
    6. Click on the arrow next to whatever is currently displayed under "Internet Access" and select Permit All.
    7. Repeat the previous step, this time for "World Community Grid" under the Programs list.
    8. Click the OK button, and close the Symantec Client Firewall using the X in the upper right.
    If "BOINC Client" or "World Community Grid" are not listed as a Program under "Manual Program Control" you can add it by clicking the Add button, and adding 2 programs. Both programs are in the location where the World Community Grid BOINC client was installed (usually C:\Program Files\BOINC). First select "boinc.exe". Then click Add again and pick "boincmgr.exe".

    How do I determine why I cannot connect to the World Community Grid servers?
    To determine why you are not receiving or sending workunits to World Community Grid, make sure you are using the latest version of the BOINC software and check your client firewall to ensure that the 'BOINC client' software reflects "permit all" or similar verbiage that your firewall software uses to reflect an approved program.

    If you are on the latest version and your firewall is set to allow the BOINC client to communicate, then please double click on the World Community Grid or BOINC icon in your system tray. Select messages and see if you have any entries like the following:

    09/10/2007 14.30.14|World Community Grid|[file_xfer] Started upload of file li349_00025_8_0

    If you do, then you may need to set your proxy. Here is the FAQ that describes how to set your proxy. If you do not know your proxy information here is the FAQ that will help you obtain your proxy information.
    Return to Top 

    How do I find out my proxy information?
    Your proxy settings are available in your Web browser. In Internet Explorer, these are under [Tools][Internet Options...][Connections] then choose either [LAN Settings] or [Settings] for your dial-up options. If "Use Proxy" is checked, click on the [Advanced...] button to see your proxy settings.

    You will need to take these settings and enter into the BOINC version of the World Community Grid software. Instructions for doing this are found in this FAQ
    Return to Top 

    How do I configure the software to use a proxy?
    The software can be configured to use a proxy in the following way:
    • Double click on the World Community Grid or BOINC icon in the system tray
    • When it opens, if you see some text that says select 'Advanced View', then click on it
    • From the options on the top of the screen select 'Advanced' -> 'Options'
    The dialogue that opens has tabs that allow you to enter in your HTTP or SOCKS proxy information.

    Return to Top 

    I entered in my proxy information but I still cannot get work. How do I get it to work?
    If after you enter your proxy information and you still see messages such as those displayed in the FAQ "How do I determine why I cannot connect to the World Community Grid servers?" above, then you will need to take the following additional steps:

    Make sure you are on the latest version of the World Community Grid agent by following the directions in this FAQ.

    If this doesn't resolve the issue, then you will need to determine what type of proxy authentication you are using. To determine your proxy authentication please refer to this FAQ.

    Once you have determined your proxy authentication, open windows explorer and go to C:\Program Files\BOINC . In this directory you will see a file called cc_config.xml . Assuming you are using windows, right mouse click on the this file and select 'Open With' and select 'Notepad'.

    This will open a new window that will be populated with the contents of your cc_config.xml file. It will look something like the following:

    <cc_config>
     <log_flags>
      <file_xfer_debug>1</file_xfer_debug>
      <http_debug>1</http_debug>
      <http_xfer_debug>1</http_xfer_debug>
      <proxy_debug>1</proxy_debug>
     </log_flags>
    </cc_config>

    You want to replace this with additional settings for your 'ntlm' or 'basic' proxy.

    <cc_config>
     <log_flags>
      <file_xfer_debug>1</file_xfer_debug>
      <http_debug>1</http_debug>
      <http_xfer_debug>1</http_xfer_debug>
      <proxy_debug>1</proxy_debug>
     </log_flags>
     <options>
      <force_auth>xxxxx</force_auth>
     </options>
    </cc_config>

    Replace the above 'xxxxx' with either ntlm, basic or gss-negotiate based on what type of authentication you are using and save the file.

    In order to make the software re-read the file do the following:
    • Double click on the World Community Grid icon in the system tray
    • When it opens, if you see some text that says 'Advanced View', then click on it
    • From the options on the top of the screen select 'Advanced' -> 'Read config file'
    Finally, in order to check that you are able to download work, please do the following:
    • Select the 'projects' tab
    • Select World Community Grid from the list
    • Click on the 'Update' button.
    • Go to the messages tab
    If all is working correctly, then you will see that you are downloading work and you will start processing it. If this has not helped you, then you can seek further help in the forums or by contacting us through the contact us feature on our website.

    Return to Top 

    How do I figure out what type of proxy authentication I am using?
    First, make sure you are using the latest version of the software. Instructions on how to do this are available in this FAQ

    Second, there are some types of proxies that need additional settings to work with World Community Grid. The first thing you need to do is to enable some additional logging for the client. You can do this by downloading this file and placing it into your BOINC installation directory (on Windows this is usually C:\Program Files\BOINC). You now need to double click on the World Community Grid icon in your system tray (bottom right hand corner of your computer screen, by the date and time), select "Advanced View", then on the menu across the top of page select "Advanced", and then "Read config". Now more information will be logged.

    In the Advanced View of the agent, go to the 'Projects' tab, click on World Community Grid, and then select 'update'. Next go to the "Messages" tab. You will see messages going by. The critical one to look for is the line that includes "Proxy-Authenticate" like the ones shown below. There will be one or more of these in a row. You are interested in the first one.

    07/04/2008 18:18:09||[http_debug] [ID#0] Received header from server: Proxy-Authenticate: Negotiate
    03/25/2008 12:24:54||[http_debug] [ID#0] Received header from server: Proxy-Authenticate: NTLM
    03/25/2008 12.24.54||[http_debug] [ID#0] Received header from server: Proxy-Authenticate: Basic realm="realmname"

    Take note of the following:
    • If the first line contains "Negotiate" then you are using gss-negotiate authentication
    • If the first line contains "NTLM" then you are using ntlm authentication
    • If the first line contains "Basic" then you are using basic authentication

    Return to Top 

    Do I have to do anything on a daily basis?
    No. Once you have downloaded and installed the agent, there's nothing that you have to do. The agent will run on your device whenever it determines that there is unused processor capacity available. When it finishes with a calculation, it will send the completed work to the grid server and then ask the grid server for more work.
    Return to Top 

    How do I check to see if I have the latest version of the World Community Grid application?
    You may check what version of the World Community Grid - BOINC agent you have by right clicking on the World Community Grid, or BOINC, logo in your system tray and selecting the item that says 'About World Community Grid - BOINC Agent' (in some cases it will say 'About BOINC'). This will display a window. The version you have installed is shown next to the text on the window that says 'Version: '

    You can check which version of the World Community Grid - BOINC Agent that World Community Grid has currently released by visiting this page: https://secure.worldcommunitygrid.org/ms/viewDownloadAgain.do . The version number is displayed below the name of the agent for each operating system. If this number is the same as the version number that you have installed then you have the latest version.
    Return to Top 

    Do I have to leave my device on all the time for this to work? Or always be online?
    The software can run only when your device is on. The software doesn't need to be connected to the Internet to work its task, but once finished, it needs to reconnect to return data and to get a new task to work on. We do not ask our members to change their normal habits and schedule for using the device. The software will adapt to your usage patterns and only utilize the device's processing power when you don't otherwise need it.
    Return to Top 

    Will running the World Community Grid Software affect my regular use of my device?
    No. Configured correctly, the software will never interfere with your ability to use your own device. Most devices never use all of their resources and it is estimated that up to 90% of the processing power of an individual device can go unused. The World Community Grid distributed computing model is based on the ability to utilize this "idle" capacity from individual devices.
    Return to Top 

    How do I make the software recognize the free space on a separate drive/partition?
    The software will only recognize the free space on the partition on which it is installed. If you have a drive/partition with more free space that you want the software to use, you must install the software to that drive/partition.
    Return to Top 

    Why does the software immediately download a large file as soon as it is started?
    The task downloaded by your software is comparing small pieces of data against a larger database. In order to make this task effective and to maximize the potential of your machine, it is necessary to keep some data locally. For the time being, this is a one-time download. Subsequent tasks may or may not have an up-front download depending upon the nature of the computational problem.
    Return to Top 

    My computer seems to be running slow since I installed the World Community Grid agent?
    If your computer seems to run slower when running the agent, then you may have relatively little memory in your system. Using 100% CPU alone will not slow things down because the agent runs at lowest priority so that it yields to any other work. Otherwise, it consumes the unused CPU which makes the total go to 100%. However, if your system has relatively little real memory (usually about 512 meg or less) and you are running other memory hungry applications, then there might be disk paging delays. To solve the problem, you could set your agent to run in screen saver mode only. Then, while you are actively using the machine, the agent will stay out of the way.
    Return to Top 

    How do I set up the software to automatically start on Windows?
    If you find that the software is no longer starting up automatically when you start your computer, then please follow the steps below to set it up to automatically start up again:
    1. Go to C:\Program Files\BOINC using the Windows Explorer
    2. Right mouse click on the file 'boincmgr.exe' and select 'Create Short Cut'
    3. A new file is created called 'Shortcut to boincmgr.exe'. Right mouse click on this file and select 'Cut'
    4. Next go to C:\Documents and Settings\All Users\Start Menu\Programs\Startup
    5. In the folder, right mouse click on some empty space and select 'Paste'. The short cut will appear.

    The next time you restart your computer, the software will be started automatically.

    How do I set up my system so that the windows agent starts for several or all of the users that log in?
    You can place the World Community Grid icon into each of the user's startup folders (in Start Menu->Programs->Startup), which will make the agent start whenever those particular users log on. You can also place it in the startup folder for "All users" which should make it run for everyone. One way to get to these folders is via: My Computer -> Local disk C: -> Documents and Settings -> All Users -> Start Menu -> Programs -> Startup, for example.

    How do I open the windows World Community Grid agent?
    On your windows desktop, typically in the bottom right of your screen, is the system tray. It looks similar to this in Windows XP:


    In the system tray you should have an icon that looks like this:   Double left mouse click on it and you will see the agent.


    Return to Top 

    Can I use Terminal Services with the software?
    Multiple users running the software via Terminal Services is not a supported configuration at this time. Allowing multiple users to run from the same install image can cause problems, whether this is via Terminal Services or running from a shared network directory. The supported configuration is one instance of the software per machine. The software will prevent multiple instances of itself from being launched.

    How do I keep the software from running while my laptop is only using battery power?
    The software is configured so that it will not run while your laptop is on battery power.

    I need to completely stop the agent for a while. How do I do it?
    If you need to stop your agent for a little while, use the snooze icon (moon shape) on the agent. You can change the default on the preferences page (check icon). If you are running a memory intensive application for a longer period of time and notice slight delays, you might want to set the agent to run only as a screen saver. Go to the preferences window (the one with the check icon) and select "Run only as Screen Saver" and then click on "Apply". This will make the agent only run when your pc is in screen saver mode. Finally, you can completely stop the agent by first minimizing its window, right clicking on its icon in the tray at the lower right, and selecting "Exit". This causes the agent to stop until the next reboot. You can also restart it at any time using the Start menu.

    I have a result that the BOINC Manager reports as being "Ready to Report." What does that mean?
    The BOINC client returns a completed work unit to the server in a two-step process. The first step is the uploading of the calculated data (called the result file). The second step is for the BOINC client to contact the server and report that the work unit is complete and to provide additional information, including how long it took to process the work unit. The BOINC Manager will report a work unit’s status as 'Uploading' as soon as the work unit has completed. Once the file has been uploaded, then the BOINC Manager will report the work unit as 'Ready to Report'. More information about work unit status messages may be found here.

    The software keeps writing "Deferring communication with project for W days, X hours, Y minutes, and Z seconds". What does this mean and how do I get it to connect now?
    This message appears when the software has experienced a problem connecting to the server. This may be because of some problem on your local device or because World Community Grid's servers are temporarily unavailable due to maintenance or updates.

    The software will delay the attempt to reconnect because during the time that the servers are unavailable, more and more volunteers' devices will try to connect to the servers. Once the servers became available the servers could become overwhelmed if all of the local devices attempted to contact them at once. This delay mechanism reduces the chances of the servers being overwhelmed.

    Return to Top 

    Will the software run faster if I do not run the screen saver?
    Yes. The screen savers divert your computer resources to motion and graphic processing. This is not just for the World Community Grid's screen savers, but for most screen savers.
    Return to Top 

    How do I shut down or change my screen saver?
    Click on [Start] [Settings] [Control Panel], and then double click on "Display." Click on [Screen Saver]. Use the drop down menu to either change the screen saver or shut it off by selecting "None."
    Return to Top 

    Do I need to use the World Community Grid screen saver in order to contribute to World Community Grid?
    No. You may utilize any screen saver of your choice and still be able to contribute to World Community Grid. World Community Grid runs at the lowest priority and will yield to any other application but will utilize any unused computer cycles available. (Note: World Community Grid screen savers are designed to work with the science applications at lowest priority with resource limitations. This minimizes the impact on your computer's resources. Other screen savers may not be designed to run at lowest priority with resource limitation.)
    Return to Top 

    How can I change the screensaver resource limits on my computer?
    You will need to modify your Device Profile on the website. On your My Grid page, select Device Manager, and then Device Profiles. Under Profile Name, select which Profile you would like to change (Default, School, Home, etc.). Then select the Custom Profile radio button. Under Advanced Options, scroll down to the Graphics section. The defaults are set to 7 frames per second and 5% cpu usage. If you would like the screensavers to refresh quicker, change the frames per second to 30. If the screensavers are taking up too much CPU power, decrease the percentage from 5% down to 2% to keep the screen saver usage to a minimum. Click Save at the bottom of the page to save your changes. The next time your computer communicates with our website, the preferences will be updated.

    I am running SETI@home on my computer? Will I be able to run both SETI@home and World Community Grid?
    Yes and no. Any non-grid.org agent, such as SETI@home, will be able to continue to run on your computer after you download and install the World Community Grid agent. However, while you can run both clients at the same time, SETI@home runs at a higher priority than the World Community Grid agent, so SETI@home will receive all the extra available CPU cycles and will starve the World Community Grid agent. Because of this, you should only run one or the other at any given time.

    What are the advantages of running World Community Grid on a computer's graphics card?
    A few years ago, the graphics card manufacturers realized that graphics cards could perform certain types of computations significantly faster than the central processing unit (CPU) inside a computer. As a result, they extended the capabilities of some graphics cards so that they could run tasks that were written in a specialized development language. As a result, applications that are modified to use this specialized development language and can leverage the graphics cards specialized capability appropriately, can potentially run many times faster on the graphics card than on the CPU. The advantage of running World Community Grid on your computer's graphic card is the fact that you can expect to complete more research then you would be able to complete using just your CPU.

    However, graphics card processing is different than CPU processing in that graphics card processing does not have the same sophisticated operating system capabilities that allow us to make sure that running the research does not interfere with your use of your computer. Many graphics cards can run World Community Grid without any interference, however, some will cause your computer to be slow in responding to you.
