Hi Ole, OpenBLAS recently added IceLake detection: https://github.com/xianyi/OpenBLAS/pull/3233
This has been patched in EasyBuild for OpenBLAS 0.3.12 and 0.3.15: https://github.com/easybuilders/easybuild-easyconfigs/pull/12865 Regards, Simon -----Original Message----- From: easybuild-requ...@lists.ugent.be <easybuild-requ...@lists.ugent.be> On Behalf Of ole.h.niel...@fysik.dtu.dk Sent: 28 May 2021 13:40 To: easybuild@lists.ugent.be Subject: [easybuild] Build fails for OpenBLAS-0.3.12-GCC-10.2.0.eb on Intel Ice Lake processors Hi, I'm building our software stack on a new Intel Ice Lake server (Xeon Gold 6342 CPU @ 2.80GHz 24 cores dual-socket) running AlmaLinux 8.4 (RHEL 8.4 clone).
