Topic 190547

Well. I have managed to sign myself up to this. I have joined Einstein, SETI and Rosetta splitting my CPU 150,50,100 respectively. In my work sheet, I have two tasks from Einstein, one from SETI and one from Rosetta. Only two ever seem to be running at one time. Why is this and is it possible to have all four running?

Thanks for any help of advice

Stuart

Only one project per CPU at one time.

SO does this mean that BOINC

SO does this mean that BOINC thinks my machine (one) has two CPUs and swaps the projects between them after a defined time period

Yes. Look here.

Edit: Try changing your general preferences.

Yes. Stick's comment should read:

"Only one project per (virtual) core at one time."

Michael

PS: Your CPU is an Intel with HT (hyper threading) so you have
one CPU, one real core, two virtual. BOINC makes no difference between
real and virtual, so you will always have two BOINC applications running.

Michael,

I am over my head here - but his computer is listed as: GenuineIntel Intel(R) Pentium(R) 4 CPU 3.00GHz. Does this mean he can go to 4 CPU's?

EDIT: Nevermind, I should have read your post more closely the first time.

Thanks for your replies -

Thanks for your replies - think I understand.

'Your CPU is an Intel with HT (hyper threading) so you have

So even if I edited my preferences it would still only run two at a time.

No. One socket/one real core/two virtual cores, because of HT. So two
is the maximum. Unless this is one of the latest "extreme editions".
They have one socket/two real cores/two virtual cores each, which would
make four. But they come with a price tag of 999€.

Michael,

Your English is fine. It's my reading skills that need improvement - plus, I need to brush up some on my knowledge of hardware.
