Release 6.0.1 of Scotch is out !

Francois PELLEGRINI - 2014-09-20 20:36 - Scotch

Almost two years after the release of the 6.0.0 branch, revision 6.0.1 has been released. While it is technically a bugfix release, with no apparent new features, much has changed "under the hood". # Algorithms for repartitioning and (re)partitioning with fixed vertices have been improved. # Multithreading issues have been solved. # From now on, there is no separate "*_esmumps" version. The additional libraries for MUMPS can be generated by running "make esmumps" for the sequential libraries and "make ptesmumps" for the parallel libraries.

It also comprises some new features : # The clustering features of Scotch and PT-Scotch are now available through the '-q' option of command line programs dgmap, dgpart, gmap and gpart. # Strategy string building helper routines are also available for clustering in the libScotch library. # Some internal graph handling routines have been exposed in the interface, such as for graph coarsening.
