Extreme-scale Scientific Software Stack (E4S)
==============================================

The Extreme-scale Scientific Software Stack (E4S) Project is supported by the US Department of Energy Advanced Scientific Computing Research Office and is a legacy of Exascale Computing Project (ECP). The packages distributed with E4S contain contributions from hundreds of open source community developers. The top-level packages are listed on the E4S :-
