How to optimize convolution using TensorCores.

Work With Tensor Expression and Schedules.

I was expecting much better execution times for tensor-INT8 mode since it’s supposed to have nearly twice the throughput of tensor-FP16 mode. Strangely the execution times of tensor-FP16 mode and tensor-INT8 mode are practically the same. MMA overall ranking retention in 6 years: 24/128 18,75 WMMA overall ranking retention in 6 years: 17/32 53,125 (56 if you include JJ, which i do) That gets us to about 3x less turn over in WMMA. I put together a simple test program (based on the “Programming Tensor Cores” devblogs article) to compare the execution times of INT8 mode vs. Now if we look for the lighter weight classes, the numbers are higher but still much less alarming than in WMMA, 18 out of 80 (22,5). I recently acquired an RTX card and was testing the new INT8 tensor core mode supported by Turing.
