The Extreme-Scale Scientific Software Stack (E4S)

The Extreme-Scale Scientific Software Stack (E4S) is an open source, open architecture effort to create a US and international collaborative software stack for high performance computing.  Led by the US Exascale Computing Project (ECP), E4S provides a conduit for building, testing, integrating and delivering the open source products developed under ECP.  E4S further provides easy integration of any other, non-ECP products, that are available via Spack source code installation, Spack being a meta-build tool widely used to compile a software product and its dependencies.
