Re: [bgl-discuss] PAPI counters

[Alan Gray <alang@xxxxxxxxxxxxx>]

Hi Jeff

At least the following counters are available:

PAPI_L3_TCM  -  Level 3 total cache misses
PAPI_L3_LDM  -  Level 3 load misses
PAPI_L3_STM  -  Level 3 store misses
PAPI_FMA_INS  -  Floating Multiply Add instructions completed
PAPI_TOT_CYC  -  Total cycles
PAPI_L2_DCH  -  L2 data cache hits
PAPI_L2_DCA  -  L2 data cache accesses
PAPI_L3_TCH  -  L3 total cache hits
PAPI_FML_INS  -  Floating Multiply instructions
PAPI_FAD_INS  -  Floating Add instructions

In addition, there are another 5 derived events unique to the BG/L 
architecture:

PAPI_BGL_OED     - FPU Oedipus operations
PAPI_BGL_TS_32B  - 32B torus packets sent in any direction
PAPI_BGL_TS_FULL - UPC cycles any link has no tokens
PAPI_BGL_TR_DPKT - No data packets sent on any tree channel
PAPI_BGL_TR_FULL - UPC cycles any tree receiver is full

Regards,

Alan
