CPU Utilization: only 13%?

Posted by gregg peacock at March 22. 2010

Cpu Summary: http://pub.netfirst.ca/CpuSummary.txt

OpenWind64 v00.08.00.0381

I'm attempting to generated a wind map as per the instructions. Everything seems to be running OK but I'm maxing out at 13% CPU utilization (on only 1/4 cores) which seems pretty inefficient.

With the standard settings it takes about 4 hours to run this process. Can you give me any advice for speeding this up? I'd like to run an additional iteration with a smaller grid size.

Cheers,

Gregg

Hi Gregg,

Sorry, I know this is inefficient. Unfortunately there is no way that I can see to multi-thread the calculation without doing multiple directions in parallel. This would take many times more memory and so the people still using the 32 bit version would be in danger of crashing.

I will look at changing this in the near future as most people appear to be moving towards 64 bit.
