Hi Gabe, Thanks for the suggestion, it worked. I used "se.py" file and submitted workload. It seems that for multithreaded work load, if number of threads is equal to number of cores, things work. I used --debug flag to verify whether both cores are running. But unfortunately, I have ran into another problem. This seem to work for number of cores and threads equal to 2. When I use more than 2, I get an panic error "panic: panic condition !handled occurred: Page table fault when accessing virtual address 0x14".
I have attached the console output for working ( n=2) and non working (n=3) case, do you have any suggestion on where I should look into in solving this problem? I spent lot of time on this with out making any progress.
