4 years ago The CPU mask is 8-bytes long, so supports up to 64 threads. In your case, if you want to enable, for example, the 31 and 0 threads, use the mask 0x80000001. Does it answer your question?
i have 16 cores(32 threads),and i executed:
procgov64.exe --cpu=0x1 java.exe -jar benchmark.jar=> use the 0 threadprocgov64.exe --cpu=0x2 java.exe -jar benchmark.jar=> use the 1 threadprocgov64.exe --cpu=0x3 java.exe -jar benchmark.jar=> use the 0 and 1 threadsprocgov64.exe --cpu=0x4 java.exe -jar benchmark.jar=> use the 2 threadprocgov64.exe --cpu=0x5 java.exe -jar benchmark.jar=> use the 0 and 2 threadsprocgov64.exe --cpu=0x6 java.exe -jar benchmark.jar=> use the 1 and 2 threadsprocgov64.exe --cpu=0x7 java.exe -jar benchmark.jar=> use the 0 and 1 and 2 threadsprocgov64.exe --cpu=0x8 java.exe -jar benchmark.jar=> use the 3 threadprocgov64.exe --cpu=0x9 java.exe -jar benchmark.jar=> use the 0 and 3 threadsprocgov64.exe --cpu=0xA java.exe -jar benchmark.jar=> use the 1 and 3 threadsprocgov64.exe --cpu=0xB java.exe -jar benchmark.jar=> use the 0 and 1 and 3 threadshow i can easy to assign the thread? or how i calculate the last value(like 0xA)?
