hi from spain,

while running only Boinc in one of my pc\'s i discovered through \"task Manager\" that the cpu usage of the process \"hadam3p_um_6.06_windows_intelx86.exe\" was reaching levels of 80% and more (84, 87 even 99) with continuous picks of activity with that percentages. In the simple view of Boinc manager i specified not to use more than 50 of the processor, and in the advanced view i specified not to use more than 50% of cpu time and use at most 50% of the processors in multiple processors systems. My computing preferences on climateprediction.net specify the same values that i mentioned for advanced view.

Should i use another program rather than task manager to know my cpu usage properly?
it\'s a very strange situation, can anyone tell me if there\'s something i can do? will those percentages of cpu usage affect my cpu?

I\'ve never used those throttling techniques, so I can\'t comment on them. However, as to running a CPU at 100%, no problem if the cooler fins are kept from clogging with dust. Besides, modern CPUs will throttle themselves if they get too hot. I\'ve been running my machines at 100%, including Quads and a laptop, for years without overheat problems. (One exception: a Pentium-D with a cooler issue.)

Here is a link to a very good free Temperature reporting program so you can check occasionally for changes:

Hola Newbe, benvingut al fòrum.

I think BOINC and CPDN are respecting your preferences. The computer has 2 cores. One HadAM model is using one core and the other model is not active. So 50% of the processors/cores are being used. And 50% of the available CPU time is also being used.

In the case of modern multi-core machines, some of us have noticed that one core does not do all the work while the other core is inactive. The computer shares the work between both cores. The reason is to maintain the same temperature in both cores. My Intel Core2Duo also does this.

That\'s a very nice computer. If it was mine I would allow both cores to run models at 100%. I\'m sure Astro would do the same! You could try both cores at 60% CPU time and test the temperature, then if you\'re happy increase the %.
