[opensuse-science] gnu-hpc packages
by Peter Hill 30 Oct '17

30 Oct '17

Hello, I just noticed the gnu-hpc packages in Tumbleweed recently, and I was wondering if there is an explanation of how they work somewhere? I had a look for some information or discussion, but I've not been able to find anything so far. I gather they are linked somehow to environment modules, but it's not clear to me how exactly. For instance, "petsc-devel" installs a module for PETSc, but "hdf5-devel" does not install one for HDF5. Are there certain packages we're supposed to install to get this functionality? Also, are they supposed to play nice with pkg-config? petsc-devel does install PETSc.pc, but loading the module doesn't update $PKG_CONFIG_PATH to be able to find it.

If you want to build packages against MKL in OBS, it would have to be packaged and available in OBS if you want to build dependent projects. Generally it is possible to package binary blobs, however, I'm not sure if the license would allow this. And even if it did, it is sorta-a frowned upon. I suppose it's possible to add it to the spec file as yet another flavor. To keep things manageable, it would make sense to build this using environment modules. the RPM macros I made for this currently only support building against different flavors of MPI libraries, however. I was briefly contemplating about generalizing this concept so that building against different flavors of Lapack and BLAS could be used as well, however, it was complex enough as it was working against the recursion limit of 16 in the RPM macro parser which required some tricks. Apparently the next version of RPM will have this lifted to 64 (yeah!) so this could be revisited then. Cheers, Egbert. -- Egbert Eich (Res. & Dev.)

[opensuse-science] MKL support
by Todd Rme 27 Oct '17

With the new multibuild approach, I am wondering if it might be time to revisit MKL support in openSUSE. It is not open-source, which may be a deal-killer in general. But it is freely available to open-source projects, and it can improve computational performance considerably at least on intel CPUs. It couldn't serve as a replacement for lapack or openblas, which is part of why support for it was rejected previously, but with multibuild it may be possible to support it alongside existing implementations. -- To unsubscribe, e-mail: opensuse-science+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse-science+owner(a)opensuse.org
