  In this proceedings we discuss the motivation, implementation details, and
performance of a new physics code base called Grid. It is intended to be more
performant, more general, but similar in spirit to QDP++\cite{QDP}. Our
approach is to engineer the basic type system to be consistently fast, rather
than bolt on a few optimised routines, and we are attempt to write all our
optimised routines directly in the Grid framework. It is hoped this will
deliver best known practice performance across the next generation of
supercomputers, which will provide programming challenges to traditional scalar
codes.
  We illustrate the programming patterns used to implement our goals, and
advances in productivity that have been enabled by using new features in C++11.
