"""GASNet 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,
UPC++, Co-Array Fortran, 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.
***NOTICE***: The GASNet library built by this Spack package is ONLY intended for
unit-testing purposes, and is generally UNSUITABLE FOR PRODUCTION USE.
The RECOMMENDED way to build GASNet is as an embedded library as configured
by the higher-level client runtime package (UPC++, Legion, etc), including
system-specific configuration.

# GASNet is as an EMBEDDED library within the build of the client package
# (eg. Berkeley UPC, UPC++, Legion, etc), some of which provide build-time
# selection of the GASNet library sources. This spack package provides
# the GASNet-EX sources, for use by appropriate client packages.
