CPU Utilization: only 13%?

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.

Any news on this?

Hi Daniel,


Thanks for reminding me. Yes, since the middle of last year, the Enterprise version has had multithreaded wind map calculations. I know people want MT in the open-source, but the thing is, if time is money then the Enterprise version is for you. If free is all important then the community version is for you.


The Enterprise version has come a very long way since we last talked. I'd be happy to give you another demo.


Nick
