Global arrays is a portable non-uniform memory access (numa) shared-memory programming environment for distributed and shared memory computers. it augments the message-passing model by providing a shared-memory like access to distributed dense arrays.

armci provides one-sided remote memory operations used by ga.

comex (communication runtime for extreme scale) provides vector and strided interfaces to optimize performance of remote memory copy operations for non-contiguous data.

dra (disk resident arrays) is a parallel i/o library that maintains dense 2-dim arrays on disk.

sf (shared files) is a parallel i/o library that allows noncollective i/o to a parallel file.

eaf (exclusive access files) is parallel i/o library that supports i/o to private files.

tcgmsg is a simple, efficient, but becoming obsolete message-passing library.

tcgmsg-mpi is a tcgmsg interface implementation on top of mpi and armci.

ma is a dynamic memory allocator/manager for fortran and c programs.

ga++ is a c++ binding for global arrays.

this package contains the static libraries and header files.
