The Nehalem has no possibility to measure MFLOPs if mixed precision calculations are done.
|
|
Therefore both single as well as double precision are measured to ensure the correctness
|
|
of the measurements. You can check if your code was vectorized on the number of
|
|
FP_COMP_OPS_EXE_SSE_FP_PACKED versus the FP_COMP_OPS_EXE_SSE_FP_SCALAR.
