Re: [easybuild] imkl/2021.2.0-gompi-2021a fails with 'illegal instruction' on AMD
Hi Loris, I'am not an easybuild expert but based on some experiences, I would say that such an error could appear when used GCC was built on a host with different architecture (with different processor flags) than the current target architecture (AMD EPYC). I would therefore check that the machine on which this GCC was built is indeed an AMD EPYC : normally, this is the GCC coming from gompi-2021a, so installed with EasyBuild, therefore you may have a look at the 1st line of the .log file in the GCC installation, in the "easybuild" directory, to have the hostname (and then you will have the architecture) of the host where GCC was installed. Maybe il will be also interesting to inevestigate if the GCC used in this postprocessing step is really the GCC coming from gompi-2021a. But if everything is good on these sides, then the problem is probably elsewhere.

Re: [easybuild] Which toolchain to use on AMD EPYC 9004 "Genoa"?

There's some work going on to create a toolchain around amd compilers but it's questionable how much you gain as all features these compilers and libs bring eventually end up in upstream llvm and gcc. So for Genoa look for upcoming foss toolchain built around gcc 13. For Rome and Milan existing ones with gcc 11 and 12 are already working fine. -- Jurij Pečar HPC Engineer, IT Operations, IT Services EMBL Heidelberg, Meyerhofstraße 1, 69117, Heidelberg, Germany Room 13-401
[easybuild] Which toolchain to use on AMD EPYC 9004 "Genoa"?
In an upcoming procurement we plan to use a GPAW EasyBuild module for benchmarking. On 4th Gen Intel Xeon Scalable processors we should presumably specify a recent "intel" toolchain because of support for the latest instructions. Question: Which toolchain to use on AMD EPYC 9004 "Genoa"? There are a number of sites out there with AMD clusters, and I wonder which optimal and reliable toolchains people use with AMD Rome and Genoa? We have often used the "foss" toolchain on Intel Xeon because it provides OpenMPI, OpenBLAS, ScaLAPACK, and FFTW modules for the GPAW code. Is "foss" also the preferred toolchain on AMD Rome and Genoa? Looking at the long toolchain list in https://docs.easybuild.io/version-specific/toolchains/ I'm not much wiser :-( None of these toolchains seems to use the AMD AOCC compiler, and I wonder why? Thanks for sharing any advice and experiences! Best regards, Ole -- Ole Holm Nielsen PhD, Senior HPC Officer Department of Physics, Technical University of Denmark
