At SC08, Aggregate.Org/University of Kentucky demonstrated open source technology for running arbitrary MIMD programs directly on GPUs. There are two environments for MOG, a simulator which interprets the MIMD code and a “Meta-State Converter” compilation system which does state space transformation of MIMD code into pure (SIMD) native GPU code. Applying the current version of either, MIMD C code using shared memory communication can do recursion, etc., while running on a CUDA GPU. Support for both C and Fortran, with both shared memory and MPI for communications, and support of both NVIDIA CUDA and ATI CAL targets, is planned. The work is very new, but detailed publications, performance benchmarks, and code releases are expected to start to appear by early next year. (MOG at SC08)
