A dialect of FORTRAN which contains extensions that make supercomputing easier. Namely, these extensions (which appear as comments to traditional FORTRAN compilers so that they can still compile HPF code) allow the programmer to explicitly divide Tensors between nodes, but still treat them like a normal, local data structure and, for example, multiply two matrices with a simple command. The compiler takes care of the inter-node communication this requires, using MPI. If the division was done wisely, there hopefully won't be too much of it.
