#1674: Switch to OpenBLAS
by Roland Haas 12 May '23

12 May '23

#1674: Switch to OpenBLAS Reporter: Erik Schnetter Status: wontfix Milestone: Version: development version Type: enhancement Priority: minor Component: Other Changes (by Roland Haas): status: wontfix (was open) OpenBLAS is a BLAS and LAPACK library that is significantly more efficient that the standard ("reference") BLAS. I suggest we switch the ET thorn list to ExternalLibraries/OpenBLAS instead of ExternalLibraries/BLAS and ExternalLibraris/LAPACK. **Keyword:** Comment (by Roland Haas): One more ticket down! -- Ticket URL: https://bitbucket.org/einsteintoolkit/tickets/issues/1674/switch-to-openblas

#1674: Switch to OpenBLAS Reporter: Erik Schnetter Status: open Milestone: Version: development version Type: enhancement Priority: minor Component: Other Comment (by Roland Haas): This ticket has been around for a while. I would still think that since OpenBLAS is x86 specific and even on x86 machines fails to compile if the processor is too new \(or old I guess\), I would not want it to be the default. Instead clusters where indeed we could compile BLAS and LAPACK libs from scratch can use simfactory’s `enabled-thorns` and `disable-thorns` options to enable OpenBLAS. If we do not compile, which is the usual case on clusters, then there is no difference between using BLAS/LAPACK externallibraries and OpenBLAS. That leaves the case of user workstations and unknown clusters. On a user workstation, with automated setup, speed should not matter so I would strongly advocate to use the “compiles everywhere” BLAS and LAPACK even if they are slow. In particular since the ET as a whole doe not depend on those for speed. On clusters, speed does matter, but setting up on a cluster requires some expertise anyway and we should be able to expect that those doing so will be able to set the correct LAPACK\_DIR and BLAS\_DIR variables to point to the system installed good BLAS / LAPACK library. If there are indeed HPC clusters where those libraries are not provide, then those clusters may be best avoided. -- Ticket URL: https://bitbucket.org/einsteintoolkit/tickets/issues/1674/switch-to-openblas

To simplify matters I wrote, couple of days ago, a wiki entry with the steps: [https://docs.einsteintoolkit.org/et-docs/Release\_Process#add\_gallery\_run… ‌ which may help. In principle all can \(and should\) be done by the runners themselves. -- Ticket URL: https://bitbucket.org/einsteintoolkit/tickets/issues/2173/test-poisson-equa…
