It works fine even if a client has never ran all of the apps.

srbase = Sierpinski / Riesel Base
srbase2 = Riesel Base
srbase3 = Sierpinski Base
srbase4 = Sierpinski / Riesel Base - short

These aren't even long enough run times to need mt setup.

If the app_config from the FAQ isn't working its because of the part in ( ).
<avg_ncpus>4</avg_ncpus> (for WUprop optional)


I'm running the Sierpinski / Riesel Base - long workunits, do you happen to know the name and number of it?

I agree the ones you listed aren't worth assigning multiple cores for.

ps--never mind I guessed and counted down from the top of the app page and it's srbase5. The file is now working running 3 wu's at a time and using 6 cpu cores for each one.

pps--well poop!! Every wu running multi-threaded crashed after running for 5 1/2 days single threaded, I thought that might happen but was getting concerned that they wouldn't finish in time if I left them alone.

Sorry to all my wingmen I was trying to return them in time!!

That's ok,

I'll just run with this.....

<app_config>

<project_max_concurrent>24</project_max_concurrent>

</app_config>

If there is a better way I'm all ears....


That has very little to do with multi-threading, all that does is tell your pc to run a max of 24 workunits at a time.

You need something like this:
<app_config>
<app>
<name>llrSR5</name>
<fraction_done_exact/>
<max_concurrent>1</max_concurrent>
</app>
<app_version>
<app_name>llrSR5</app_name>
<cmdline>-t 6</cmdline>
<avg_ncpus>4</avg_ncpus>
</app_version>
</app_config>

But this one is forPrime Grid and NOT SRBase.
Note that it has a maxconcurrent of one workunit and then is set to use 4 cpu cores for that single workunit.
