Re: [Gems-users] sequencial benchmark

[Bharat Singh <bharatsingh430@xxxxxxxxx>]

Well I can reply to your second question, the number need not be equal, but suppose if the $num_cpus in simics is 1 and you are setting g_NUM_PROCESSORS: 4, then your benchmark will run only on the 1st core, i.e ruby cycles for the others will be 0, similarly for opal. So, it wont give you error but I dont think it will be useful to make the two different.

Hi all,
 
          I use GEMS + simics to run hello world test program.  like the following
 
          int main()
         {
                  printf("hello world\n");
               
                  return 0;
         }
 
          the ruby configure is
 
          g_NUM_PROCESSORS: 2
          g_NUM_L2_BANKS: 1
          g_NUM_MEMORIES: 1
          g_PROCS_PER_CHIP: 2
          g_MEMORY_SIZE_BYTES: 4294967296
          g_DATA_BLOCK_BYTES: 64
 
          when simulation is finished, I dumped the result.
          There still had two processor  running.
          I passed NodeID  with the argument    m_chip_ptr->getID()*RubyConfig::numberOfProcsPerChip()+m_version
          The NodeID is 0 or 1.
          But I run sequencial code,  why the NodeID had two value?  
          I  use the following command
 
          instruction-fetch-mode instruction-fetch-trace
          istc-disable
          dstc-disable
          cpu-switch-time 1
 
          Another question:    Is  simics  and  GEMS  the number of processor configuration  must the same ?
          Because  if the number is different,  the simics would output error  and  end up simulation.
 
          Above two questions, is there something wrong?
 
          Thanks for your help!
         
Allen
