description: "GASNet-EX is a portable, open-source, high-performance communication\
  \ library designed to efficiently support the networking requirements of Partitioned\
  \ Global Address Space (PGAS) runtime systems and other alternative models in future\
  \ exascale machines. The library is an evolution of the popular GASNet communication\
  \ system, building upon over 15 years of lessons learned. \n\nGASNet is a language-independent,\
  \ networking middleware layer that provides network-independent, high-performance\
  \ communication primitives including Remote Memory Access (RMA) and Active Messages\
  \ (AM). It has been used to implement parallel programming models and libraries\
  \ such as UPC, Co-Array Fortran, Titanium, Legion, Chapel, and many others. The\
  \ interface is primarily intended as a compilation target and for use by runtime\
  \ library writers (as opposed to end users), and the primary goals are high performance,\
  \ interface portability, and expressiveness. GASNet stands for \"Global-Address\
  \ Space Networking\". \n"
