Why do you need it?

Useful for depended software. Many updates. This package used in OpenFOAM, one of the biggest open source CFD program. Is this a reason to update from 12 years release?

Main changes since 5.x version:


Version 7.0 of SCOTCH release (codename « Sankara »), fruition of six years of development, brings many major improvements. Notably:

1)    Thread management is now fully dynamic: Scotch automatically adapts its behavior to the number of available cores. An existing thread pool can be imported from a caller software, so as not to create unnecessary threads and to improve computation locality.

2)    Many algorithms have been rewritten to benefit from shared-memory parallelism, including some algorithms of PT-Scotch, which now benefit from a hybrid « MPI+threads » parallelism.

3)    Execution options, such as the fact to select between deterministic algorithms that allow for computational reproducibility or faster, non-deterministic algorithms, can now be selected dynamically and no longer at compile time.

4)    A new class of objects is available: execution contexts. Contexts allow users to encapsulate a thread pool, execution options, and a private pseudo-random generator, so as to execute concurrently (and in a fully reproducible way) any Scotch computation (mapping, partitioning, ordering, etc.) on the same graph or on different graphs.



Version 6.0 of SCOTCH offers many new features:

    sequential graph repartitioning;

    sequential graph partitioning with fixed vertices;

    sequential graph repartitioning with fixed vertices;

    new, fast, direct k-way partitioning and mapping algorithms;

    multi-threaded, shared memory algorithms in the (formerly) sequential part of the library;

    exposure in the API of many distributed graph handling routines;

    embedded pseudo-random generator for improved reproducibility;

    and even more...
