Massive supercomputing coping with heterogeneity of modern accelerators
2008
Proceedings, International Parallel and Distributed Processing Symposium (IPDPS)
Preserved Fulltext
Heterogeneous supercomputers with combined general-purpose and accelerated CPUs promise to be the future major architecture due to their wide-ranging generality and superior performance / power ratio. ...
For this goal, we divide porting of applications into several steps, analyze performance of the kernel computation, create processes that virtualize the underlying processors, tune parameters with preferences ...
Despite the fairly long history in supercomputers with vector acceleration options such as the CM-5 and the Meiko CS-2, and the recent high interest on SIMD-vector programming, there have been little results ...
