Re: [Gems-users] memory accesses

[Polina Dudnik <pdudnik@xxxxxxxxx>]

Are these the parameters from .stats file or from the script or from the default configurations?

Are you sure that out of the three conditions

 if (IS_DEV_MEM_OP(mem_trans->s.ini_type) ||
      IS_OTH_MEM_OP(mem_trans->s.ini_type) ||
      mem_trans->s.physical_address > uinteger_t(RubyConfig::memorySizeBytes())

It is the third one that is true? 

The reason I asked you what is inside your transaction is because I though that maybe you had some IO. But it seems like you have a very simple transaction. Are you sure the rest of your setup is right: like you are binding the threads and everything?

Yup, I wrote my own workload. Its really simple, I'm just incrementing
a global variable. It looks like:

-------------------------
for(i = 0 ; i < num_ops ; ++i)
{
  BEGIN_TRANSACTION(0)
  temp = counter;
  temp = temp + 1;
  counter = temp;
  COMMIT_TRANSACTION(0)
}
------------------------
counter is global variable and temp is local.

I'm attaching the ruby parameter list.
