Hi All,

Just want to know if there is some way of controling the CPU's uasge in running 2 BONIC clients. 1st instance of this is 10% complete and 2nd instance is only 1.5% complete after installing 2nd instance last night. My problem is the CPU is throtttling along at 100%, so how do I turn down (preferably) the 2nd instances usage of the CPU Without interfering with the performance of the 1st instance?


Many thanks in advance.

You only need one BOINC. If the preferences setting is to use 2 CPUs, then you should be running two models. If this setting is to use at most 1 CPU ... then it will only use one at 50% ...

Set your preferences for 1 CPU on the web site.

BOINC WIKI

BOINCing since 2002/12/8

so when i take my A+ class and learn how to make a computer from scratch if i make a tower with say 10 opterons, i can have nine of them running wu's and the last one for me. I could judt use the computer like it was a single processor machine and ignore the other 9.

I think I'd like to see what that motherboard(s) looked like. However in principal set use at most 9 processors in your preferences and this should do what you want. I don't know if the hard disk might be a bit stretched for input/output so the output may not be as good as 9 seperate opteron machines.

Don't forget that with HT it isn't a perfect 50 / 50 split in processing power between the two WU's. The second WU will always be slower to process. Just the way how HT is with the P4 processor.
