I run BOINC continuously on several machines and have a thermal challenge on one of them. Room or whole house air conditioning is not available for several reasons, so I must use various strategies to maintain a reasonable inside temperature, however with the California temperatures daily reaching 90+ in the summer, this is a serious challenge.

The problem machine has a pentium dual-core chip.

One solution is to shutdown the machine or suspend BOINC processing during the daily high-heat periods, but this does not advance our mutual goals for running the projects.

A second choice is to change from two processors to one for the duration of the severe heat period. This is an acceptible alternative, but comes at a price.

One must visit each active project website and switch the machine from a two processor profile to one with a one processor limit, return to the client, press UPDATE in each active project, wait for the benchmarks to complete and do the same for the rest of the active projects. Then, when the stress is over, you have to do the same procedure to revert to the original two processor configuration.

A much simpler solution would be to enable such a change at the BOINC client which would then affect all active projects alike.

Thanks,
Jim Wright

In the next version there is a global change that allows you to cut back to say 85% processor usage. This is changable in one project and should be accepted by all projects. So, this may be an easy work around that you want.

That might work. Let's hope it can be made available soon.

I live in Sacramento and have not had a heat problem unless my box's get to many dust bunnies living in my case's lol... Am running 2 840ees with HT enabled and have no problems, of course today it is close to 106F. Running two laptops one is a dual and they run 24/7.

Air is running today.....lol Usually air is not on until it gets over 90 outside, which is about 82 inside...

Jim I would going to talk to you about 'optimised' versions of the Boinc software. I also have a P4D840EE and am doing 4 units, all at once, and only taking about 12,000 seconds to do the work! You are taking about 25,000 seconds to do the same thing! I got the optimised version from http://www.zadra.org/seti_enhanced/index.php?module=Downloads;catd=4 Mine WAS running about 86C! until I swapped in a Zalman fan, that dropped the temp about 5 degrees. Moving the box so the side of the case was closer to the a/c dropped the temp to 70C as we speak. Your RAC was what tipped me off, mine is 803.28 right now! Your is 253.26 and 135.04. You can see my pc here http://setiathome.berkeley.edu/show_host_detail.php?hostid=1417588
I live in Northern Virginia and the heat is into the 90's all week!
