Is there a way of querying a SGI with R10K processor (specifically the
Power Challenge, Origin200, Octane and O2 architectures) for the
configured size of its secondary cache lines?
I have been looking at the list of typical cost (see 'perfex -t') of
each event that may be counted on the Performance Counters. On an Octane
it reports 396 cycles and on Origin200 only 76. Could someone please
briefly explain the reason for this? Or even better; is there an
accessible document that explains it?
Thank you in advance
