[Gems-users] opal stats qn

[sudrang@xxxxxxxxxxxx]

Hello,
Im confused a bit abt the runtime stats of opal.

[0] *** Runtime statistics:
[0]   Total number of instructions                        641511246
[0]   Total number of cycles                              397438255
[0]   number of continue calls                            641511246
[0]   Instruction per cycle:                             1.61412

usec
[0]   Approximate cycle per sec:                         12607.5
[0]   Approximate instructions per sec:                  20349.9
[0]   This processor's Simics overhead (retire/elapsed):  54.96%

The approximate cycle per sec confuses me. Where did this number come from?
My configuration file models an alpha 21264 at 466Mhz(This is irrelevant
given that we talk in terms of cycles everywhere), my target pc(serengeti)
has a frequency of 75 Mhz and my host pc runs at 3Ghz.
I just need execution time for the benchmark, the total number of cycles
here are for the actual benchmark on the target machine..right(I dont want
the work done by the host machine)?

Thanks,
