Programs and libraries for graph, mesh and hypergraph partitioning

Edit Package scotch

Programs and libraries for graph, mesh and hypergraph partitioning Its purpose is to apply graph theory, with a divide and conquer approach, to scientific computing problems such as graph and mesh partitioning, static mapping, and sparse matrix ordering, in application domains ranging from structural mechanics to operating systems or bio-chemistry.

The SCOTCH distribution is a set of programs and libraries which implement the static mapping and sparse matrix reordering algorithms developed within the SCOTCH project.

It doesn't seem possible to link in a serial scotch library with any of the SLE_15 variants. Is this an oversight, or are there symbol conflicts with the respective MPI variants?

Would expect something like this around line 360:

# Don't build non-HPC on SLE, but serial is still ok
%if !0%{?is_opensuse} && !0%{?with_hpc:1} && "%{flavor}" != "serial"
ExclusiveArch:  do_not_build
%endif

General note for scotch maintainer(s):

with OpenFOAM we noticed some regressions with scotch-7.0.1 (perhaps other versions too) and are thus currently sticking locally with scotch-6.1.0 - so some caution may be needed if/when update versions here.

In homebrew (for example), they have aggressively enabled -DSCOTCH_PTHREAD_MPI, which means that any program using ptscotch will fail if MPI is not initialized with MPI_THREAD_MULTIPLE (we normally do not use MPI threading for performance reasons). It would be nice to avoid that here.
