Re: n=40 but load (and threads) seem to imply n=48 being use

Thanks everyone. I have it running two slots now, a 32 and an 8. The load is now hovering at 40.7 with system load percentage about 8.7%. Like toTOW mentioned, it seems that combinations of CPU counts which cannot be properly factored just find the nearest "round" number. I couldn't do two...

Re: n=40 but load (and threads) seem to imply n=48 being use

Well, in 45 minutes, that's only two checkpoints if I use 15 minutes, before it's sent...and this system isn't even using a hard drive. So, I get eight or so checkpoints now over the life of the run. That's pretty small. The top command can show threads if you use the "-H" flag. It's not s...

Re: n=40 but load (and threads) seem to imply n=48 being use

VERY interesting result with n=32. It completes much more quickly, with "system" load now down to 10%. Also notice how equal the time share each of the threads becomes. This one finished in ~45' compared to a consistent ~69' with n=40. Wow. But like I mentioned before, I had turned this do...

Re: n=40 but load (and threads) seem to imply n=48 being use

I had actually turned it down to n=36 the other day but it was still using more CPU than I expected, Bruce. I will try turning it down to 32 and see what that does to the times. Currently, the runs are all finishing in a bit more than an hour (~69'). I also find it, uh, interesting that the system i...

n=40 but load (and threads) seem to imply n=48 being used

I have an E5 server with 40 threads. In the config.xml file, I specify that the number of processors is 40. (And also that the client-type is advanced and the max-packet-size is big, in case that matters.) Usually, I would expect system load to equal 40, but on this system, it is at 48. In fact, if ...
