Motivation
Explicit gemm solvers are on some occasions 500 - 1000s of times slower than the winning solver. We would like to prevent the testing of these mal-performant gemms such that tuning time is not needlessly lengthened
Technical Details
This change add function IsSlow to the gemm solvers to return if the gemm is predicted to have poor performance for the current convolution. And will be skipped if the function returns true.
Test Plan
Rules tested against collected tuning data. The rule sets are scored by selection metrics taking into account True Positives and False Positives as a percentage of the sampled convolutions where each solver was applicable.
