--- Comment #5 from Michael_S <already5chosen at yahoo dot com> --- Hi Thomas Are you in or out? If you are still in, I can use your help on several issues. 1. Torture. See if Invalid Operand exception raised properly now. Also if there are still remaining problems with NaN. 2. Run my correction tests on as many non-AMD64 targets as you can. Preferably, with 100,000,000 iterations, but on weaker HW 10,000,000 will do. 3. Run my speed tests (tests/matmulq/mm_speed_ma) on more diverse set of AMD64 computers than I did. Of special interest are - AMD Zen3 on Linux running on bare metal - Intel Skylake, SkylakeX, Tiger/Rocket Lake and Alder Lake on Linux running on bare metal I realize that doing speed tests is not nearly as simple as correctness tests. We need non-busy (preferably almost idle) machines that have stable CPU clock rate. It's not easy to find machines like that nowadays. But, may be, you can find at least some from the list. 4. Run my speed tests on as many non-obsolete ARM64 computers as you can find. Well, probably a wishful thinking on my part. Also off topic but of interest: postprocessed source of matmul_r16.c
