There is a little on the website about Linux. Look at http://www.worldcommunitygrid.org/help/viewTopic.do?shortName=linagent

killall boinc



nohup ./boinc >& /dev/null &


If you stop boinc before running 'run_manager' the manger program can not connect to boinc - nothing to manage. So always start boinc before starting run_manager.

Ok let me take a stab at this. I'm going to repeat some information and probably also answer the question at a lower level becuase others might have the same questions as you.

There are 3 major tools installed when download and install BOINC.

The BOINC Core Client
The first is the BOINC core client (which is the only thing we talk about on the download and install page). Lots of information about it is available at: http://boinc.berkeley.edu/client_unix.php

The BOINC Manager
The second is the BOINC Manager. This is a GUI tool that can make administration of the BOINC core client easier. It also allows you to check the status of your workunits. Lots of information about it is available at: http://boinc.berkeley.edu/manager.php

The BOINC Command Line Tool
The third is the BOINC command line tool. This is a non-gui tool that allows you to check the status of the core client and do most management tasks. More information about it can be found here: http://boinc.berkeley.edu/boinc_cmd.php

Ok - I think you have figured most of the above out but I thought I would point you to the links in case you had more questions about them.

Starting BOINC
Next - you asked how do you start the client and keep it running after you close your shell. As prause said - you need to run the following command:

> nohup ./boinc >& /dev/null &

nohup makes sure that the process is not killed by the operating system after you close your shell.

The & means run the process in the background. This lets you continue to use your shell after starting the command.

How do I know if BOINC is running?
Next - how do you check to see if BOINC is running. What you actually want to check is if the science application running. In this case it is rosetta. One easy way to do it is to run the command

> top

In this display you should see a process named 'rosetta_4.21_i686-pc-linux-gnu' using a large portion of the cpu time (you will see multiple processes if you have more then one processor). If you see this then you know that BOINC is successfully running the World Community Grid Human Protoeme Folding Project.


Stopping BOINC
Finally - how do you stop BOINC? The easiest way that I have found is to run the command:

> pkill boinc

And it exits shortly afterwords.

cd into the directory where you have installed BOINC

then run

./boincmgr

The 'run_manager' script that people have mentioned above simply does these steps for you (just take a look at the file).

Make sure that BOINC is running first (via techniques discussed above)

Obviously, since the manager is a GUI you need to be in an environment capable of displaying it (i.e. not logged in remotely).

Sorry we posted at the same time ... I'm a slow typing.

yes and a slow learner.
