hi ZacD. Thanks for your reply. I think i just fixed it. Its working fine now. 30 minutes ago mental ray was using only 8 cores. Other cores cpu usage was like 1 or 2%:P . I dont know why but its working fine now thank you
update
but maya output window says
"initMPS with licenseOption 0
mental ray: got 8 satellite CPUs." what does it mean? When i look task manager all cores using 100%
Its says "8 CPUS" because technically your computer (I am guessing) only has 8 physical cores. Cores and Threads are completely different. If you have HyperThreading on your CPU, then it will appear as if you have 16 'cores'. If you want more information on the difference between cores and threads, I am sure there are millions of articles on it across the internet
Maya2012 has some mental ray bugs, and sometimes struggles with recognizing the hyper threading. Before it probably read that there were 8 cores and was only rendering on the 8 threads, whereas if it read it correctly, you would be rendering across all 16 threads.
