Member Data Documentation

const char * Sacado::FlopCounterPack::FlopCounts::flopCountsNames

Names of individual flops.

{
  "="
  ,"all +-"
  ,"all *"
  ,"all /"
  ,"<,>,=="

unsigned int Sacado::FlopCounterPack::FlopCounts::flopGranularity = 100000000

static

The number of flops to accumulate as an integer before converting to a double.

The default value is 100 000 000 and must be less than UINT_MAX-1. Increasing this value may give somewhat better precision for the flop count when counting very large numbers of flops.

Definition at line 125 of file Sacado_ScalarFlopCounter.hpp.

double Sacado::FlopCounterPack::FlopCounts::flopCounts[NUM_OPS]

Individual flop counts.

Definition at line 128 of file Sacado_ScalarFlopCounter.hpp.

double Sacado::FlopCounterPack::FlopCounts::summaryFlopCounts[NUM_SUMMARY_OPS]

Summary category flop counts.

Definition at line 131 of file Sacado_ScalarFlopCounter.hpp.

double Sacado::FlopCounterPack::FlopCounts::totalFlopCount

Total flop count.

Definition at line 134 of file Sacado_ScalarFlopCounter.hpp.
