Summary: Scotch 5.1.10 is out and breaks the "32-bit" barrier
Project: Scotch


Scotch and PT-Scotch are now fully 64-bit. PT-Scotch 5.1.10 has been able to bipartition a graph of more than 2.4 billion vertices, distributed across 2048 processors, on machine Platine of French CCRT computer center, in a bit more than a minute. Weak scalability experiments were carried out up to 8192 processors on machine Hera at LLNL.

PT-Scotch now has improved load balance capabilities, which allow it to enforce almost exact load balance across domains whenever requested.

New command-line and library options allow users to tailor easily their strategies according to their needs: quality, speed, scalability, load
balance, etc.
