Benchmarking Help

Might have found the issue. I missed a p from the mpi command.

Should be

mpirun -np 8 fds5_mpi_linux_64 Scale1.fds

Well, I'll be dripped in dogs**t! It's running right now on three cores. Did install OpenMP in the meantime, by the way. I'll send the results and will let it try to run on four cores as well.
(as I suspect that a A6-3500 is actually a A6-3600 with a disabled or defect core. Sometimes BOINC is running four WUs at a time on the A6-3500...not counting GPU or nci tasks)
Triple-core run output sent, now running processes 0,1,2&3 on the 'triple'-core....

Thanks for trying again

Not sure how it worked but it did first time when I tried it. On the i3 server I'm running for the testing (and a server for myself to do some game server testing with), I got noticeably faster speeds running linux than I did on Windows. (61% slower on the single core and 83% on the multi core. That's quite a difference. I now need to do some more investigating because that's a fairly impressive difference.*

I did notice mind that the Windows install of the i3 didn't reach full clock speed during the single core run. The CPU frequency was being kept low.


*One was a Debian CLI server install and the other is Windows 2012.

For those that are interested, I deleted the Google Doc and moved all the data to Github (as I wanted to combine it with some other data on the program).

Details can be found here.
