Profiling group to measure (double-precisision) FLOP rate. The event might
|
||
|
|
have a higher per-cycle increment than 15, so the MERGE event is required. In
|
||
|
|
contrast to AMD Zen, the Zen2 microarchitecture does not provide events to
|
||
|
|
differentiate between single- and double-precision.
