FP_COMP_OPS_EXE on Silvermont?

FP_COMP_OPS_EXE on Silvermont?

Hi,

   Is there an equivalent of the FP_COMP_OPS_EXE family of events (.X87, .SSE_FP_PACKED_DOUBLE, etc.) for Silvermont chips? I am trying to use Linux "perf" to get at performance statistics of a scientific code, but from the non-architectural events listed in Table 19-18 of the Software Developer's Manual (Vol. 3), I don't see anything. If there isn't, does anyone have advice on counting FlOps and integer ops on Silvermont?

Thanks,

 

Chris

For more complete information about compiler optimizations, see our Optimization Notice.

Silvermont Performance Monitoring events do not include a FLOPS event and I believe the closest you are going to get on Silvermont are the events:

1. UOPS_RETIRED.X87

2. UOPS_RETIRED.MUL

3. UOPS_RETIRED.DIV

 

 

Perry,

   Thanks very much, that helps.

Cheers; Chris
