A comprehensive computing initiative for MFE. Revision 1

The authors propose that a national initiative by launched to develop a comprehensive simulation facility for MFE. The facility would consist of physics codes developed by the national MFE community tightly but flexibly coupled through a programmable shell, enabling effectively simultaneous solution of the models in the various codes. The world ``facility`` is chosen to convey the notion that this is where one would go to conduct numerical experiments, using a full set of modules to describe an entire device, a coupled subset to describe particular aspects of a device, or a combination of the facility`s modules plus the user`s own physics
