Storaasli reviews the State-of-the-Art in Heterogeneous Computing

Recent work by ORNL researcher Olaf Storaasli in collaboration with four Oslo colleagues at SINTEF (Norwegian NSF) has resulted in a comprehensive (31 page, 185 references) publication entitled \State-of-the-Art in Heterogeneous Computing\ recently published by the Journal of Scientific Programming, IOS Press. The publication identifies the key advances and trends over the years in computer hardware and software leading up to accelerators (Cell, GPU and FPGA) used in current and future High-Performance Supercomputers. An in-depth description, strengths & weaknesses of today's three accelerator technologies is given including details with examples (software, applications, performance and cost). Projections are made illustrating which accelerator is best suited for which application area, concluding with emerging architecture features and trends defining the hardware and software architecture of future High-Performance Supercomputers.  For more information, see the paper.
