Re: [Gems-users] Core mapping

[Venkatanathan Varadarajan <venkatv@xxxxxxxxxxx>]

Hi Hamid,

I think the mapping is done something like this:

ruby_proc_id (within a chip) = simics_proc_no/g_PROCS_PER_CHIP; //(integer division)

simics_proc_no is in [0,7] and
Hence, first four simics-processors map to four proc in first chip and next four simics-processor map to four procs in in the second chip in ruby.

Regards,
Venkat

Hello

Suppose that g_NUM_PROCESSORS is 8 and g_PROCS_PER_CHIP is 4. Therefore, there is 2 chip that eache of them contain 4 physical processors. On the other hand, each physical processor in Simics has a number (Suppose 8 cpus are defined in Simics). Could you tell me how I can determine which processors belong to chip1? On the other words, Which processors are shared one L2 cache?

Best Regards.
