I've never seen the behaviour George describes here. It only ever
runs P-1 factoring in the hours I set at night. I do set the day time
memory to 8MB, so maybe that explains what I see.
I have recently starting using Quad Core machines too. One thing I've
done is to set the night time for one instance of Prime95 to be 7pm to
midnight and on the other instance from midnight to 8am. This would
solve the problem of having more than one core running P-1 factoring at
the same time on a dual-core machine. However, I would like to give
more flexibility in setting night time so on some cores I could set
night time to say 4am to 8am. That way I could sub-divide the whole
night between all four cores so that they would never be two doing P-1
factoring at the same time. Maybe this is already possible I've not
actually experimented.
Doug.
