I run ECM with a separate copy of Prime95, stored in its own directory.
This ends to reduce complications. I can also run ECM simultaneously
with LL testing this way, and keep separate results files for both kinds
of work.
This brings me to a couple of questions:
1. Is it okay to add a mark to the ECM copy's results.txt file to remind
myself which results entries I have sent to George? I don't want to
change the file manually if the program ever reads it and depends on its
being in a certain format.
2. Is it less efficient to run two copies of Prime95 simultaneously one
a single-processor machine than to run them sequentially? They share
processor time (as reported by WinTop) equally when both are working,
but perhaps something is lost in the need to time-share two
FPU-intensive programs.
[Oddly enough, I have noticed that sometimes when I start the ECM copy
of Prime95, it gets 70% to 75% of CPU time instead of the usual share of
just under 50%. Can anyone explain why this happens?]
