[Gems-users] Help with understanding the opal_stats output

[Brian Hing-Kit Tsang <btsang@xxxxxxxxxxxx>]

Hi,

I was wondering if anyone could help me decipher the opal_stats output.

I believe I understand most of the output, but had a few questions.  I am
using the MOESI_CMP_directory protocol on an UltraSparcII target machine.

I want to try to figure out where the majority of the stall are in the
benchmark I ran.  Is there anyway to find the total number of stalls and
the breakdown of what % of those stalls are branch mispredictions, data
dependencies, etc... I basically want a way to determine the bottlenecks
of the system.

Thanks,
