[Gems-users] simulating an architecture

[hamid reza khaleghzadeh <khaleghzadeh@xxxxxxxxx>]

Hi

I want to simulate a multi-core simulator that it's architecture is shown at following:

Core 0     Core 1          Core 2     Core 3
   |--------------|                   |--------------|
         L2                              L2
          |---------------------------------|
                           |
                      Memory

|----------------| is Bus

This processor contains two dual-core processors.

For simulating this architecture I have done:

ruby0.setparam g_NUM_PROCESSORS 4
ruby0.setparam g_PROCS_PER_CHIP 2
ruby0.setparam g_MEMORY_SIZE_BYTES 4294967296
ruby0.setparam NUMBER_OF_VIRTUAL_NETWORKS 5

and Coherency protocol is MOESI-cmp-directory

Could you tell me I have correctly simulated considered architecture?

By the way, I have another question. If possible please answer me. I have created a 4 cores Solaris checkpoint. You know that in Simics, each processor has a number (in this case 0-3). When ruby is initialised, which cores of Simics share on L2 cache? (Is one L2 shared between core0 and core1 and another L2 shared between core2 and core3?)  

Thanks.
