Projects / GASNet


GASNet (Global-Address Space Networking) is a language-independent low-level networking layer that provides network-independent, high-performance communication primitives tailored for implementing parallel global-address space SPMD languages such as UPC, Titanium, and Co-Array Fortran. 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.
