Hi,

Can I limit a project (for example Aqua@home) via app_info.xml or any other xml file to use less than maximum number of cpu's available?

I do not desire that aqua@home uses all 48 cores, because most of the time it will make most of the cpu's idle, while waiting for few cores that are still running another project tasks (like primegrid or rosetta, etc.) in "high priority" mode.

At the moment I have to check the status every hour and click on aqua@home suspend and then resume. This will release the idle cpu's to run other tasks.

I've tried to play with max_gfx_cpu_pct in account_aqua.dwavesys.com.xml and sched_reply_aqua.dwavesys.com.xml, but it gets rewritten.

Any ideeas?

Thank you,
Ionel

No, there isn't such an option, since the project's applications are multi-threaded. The applications decide they want to use all the available CPUs, it isn't up to BOINC. So your only option would be not to run AQUA on that computer.

Now, on the other hand, there are a couple of runtime bugs in 6.10 versions of BOINC when it comes to multi-threaded and single threaded applications running side-by-side. These bugs are fixed in the next version of BOINC, so it may also be that you just need to wait for that BOINC.

So you could try running with the Alpha version of 6.12.18. Do upgrade to the recommended version of 6.12 when it is released.

Having written all that, according to one anonymous source, it is possible to do this. This source will be announcing himself in private message to you.
