As per Seti's suggestion I am running the climate program whilst there are

preference at 50% per project and my machine using 100% of CPU time on
Climate whilst there is no Seti. However, on my multi CPU machines, setting
the preference to 50% just runs 1 thread at 100% usage on 1 CPU and nothing
on the other. Is it possbile to get BOINC to 100% of all CPUs until there
are WUs available and then return to 50 - 50 share once there are?
I have the same issue. I am running linux but I don't think the OS matters.
Looking around on various web forums I saw that climateprediction does
not (at least yet) do more than one CPU.
I am not sure why boinc cannot spawn off a pair of climates like it
does with seti. Neither seti nor climate has an SMP type client
working multiple CPUs on the same data -- but that's OK I think it
would be more work than it would buy in benefit.
You can work around it by opening two accounts and launching two
boincs. This doesn't strike me as all that great.
One of these days Berkeley will start doling out workunits and then
seti can run on one CPU and climate on the other CPU.
Another method is to fire up one instance of the old setiathome.
You might also try looking into the folding project. I haven't bothered
with this yet.
