Wang Yu is still having a problem:
Thanks Jan,
I have just tried some simulations. I use different "-j" and
"--cores"parameters and found that :
When I use "-j 20" the speed is fastest. But whether it's '--cores=20' or
'--cores=10' or whatever number, the computing speed remains mediocre, show
little acceleration.
I want to know why it's different from doc's description, why the speeds are
different with -J and --cores?
Also, as you said, why isn't speed the best when using the maximum
number of threads?I hope you can give me a brief explanation.
Best regards
Wangyu
