SCOTCH has released 7.0.10.
We should include this in the next spack-stack release version. This includes a fix for the intel oneAPI issues we had with version 7.0.4
We announce the release, as libre/free software, of revision 7.0.10 of the
SCOTCH and PT-SCOTCH software package and library for sequential and
parallel graph partitioning, sequential and parallel graph clustering,
sequential mesh/hypergraph partitioning and static mapping, and sequential
and parallel sparse matrix block ordering.
This revision fixes some bugs and provides new features. In particular, the
behavior of Scotch can now be controlled at run time by new environment
variables, SCOTCH_DETERMINISTIC and SCOTCH_RANDOM_FIXED_SEED, which, like
SCOTCH_PTHREAD_NUMBER, play the same role as, and override, the compilation
flags of same names. Also, a multi-threaded genetic graph bipartitioning
algorithm is now available.
Packagers are encouraged to configure SCOTCH so as to make the widest use
of threads, that is: -DCOMMON_PTHREAD -DSCOTCH_PTHREAD -DSCOTCH_PTHREAD_MPI,
and also -DCOMMON_PTHREAD_AFFINITY_LINUX whenever possible. On Windows-like
environments, the -DCOMMON_THREAD_WIN32 flag is available.
The -DSCOTCH_DETERMINISTIC flag may be set or not, depending on former
practice, given that users can now set this behavior at run time.
Please refer to the file INSTALL.txt in the root directory.
