v5.9

• Known Bugs
  • The MPI RMA port still does poorly with older releases of MPI. Currently,
    OpenMPI 5.0.x and MPICH 4.2.x appear to do well.
• Added
  • GA can be initialized from an MPI communicator. This enables instances of GA
    to be created from non-GA programs and run independently on a subset of
    processors
  • An option to use System V memory instead of POSIX shared memory was added to
    the MPI progress ranks runtime. This option was added to get around a memory
    limitation with POSIX shared memory only allows a maximum of about half the
    available memory to used as shared memory. System V memory does not have
    this limit, but this implementation does not appear to be reliable and
    should be avoided if large memory usage is not needed
  • Substantial support for sparse 2D arrays. This includes operations such as
    matrix-vector and matrix-matrix multiplies, sparse-dense conversion and
    operations on the diagonals
• Changed
  • Updated compiler settings in CMake build if Fujitsu compilers are detected.
    Other general improvements have also been made in CMake build.
  • Removed all instances of ga_malloc from GA source code. This frees GA from
    needing to initialize MA before using GA library calls.
  • Modified progress ranks runtime to use hostnames instead of host IDs to
    identify ranks on same SMP node. This is a more robust implementation.
• Fixed
  • Fixed gcc toolchain checks in CMake for clang build
  • Fixed tiled arrays so that they work with restricted arrays and fixed some
    additional bugs in block cyclic distributions
  • Removed several memory leaks
  • Older TCGMSG implementations removed from build and documentation.
    TCGMSG-MPI is still retained
  • A substantial amount of code and documentation for discontinued or
    deprecated systems was removed. Examples include Blue Gene P/L/Q, LAPI,
    PVM, CCA, VIA, Quadrics, Elan-3/4, Myrinet GM, Mellanox, Hitachi, DEC, etc.
  • Number of outstanding non-blocking messages in MPI RMA runtime modified so
    that non-blocking test passes
