Hi Konrad, What is the output of 'lscpu'?
For instance, on machine A running on Intel(R) Xeon(R) Gold 5218 CPU @ 2.30GHz, OpenBLAS for commit 87e7faa2ae641d8302efc8b90f1e45f43f67f6da builds. On machine B running Intel(R) Core(TM) i7-10700K CPU @ 3.80GHz, OpenBLAS for the same commit fails. Cheers, simon
