The Fast Fourier Transform (FFT) plays a key role in many areas of computational science and engineering. Although most one-dimensional FFT problems canbe entirely solvedentirely ...
HPL is a parallel Linpack benchmark package widely adopted in massive cluster system performance test. On HPL data layout among processors, a law to determine block size NB theoret...
This paper introduces a new highly optimized architecture for remote memory access (RMA). RMA, using put and get operations, is a one-sided communication function which amongst ot...
This paper describes an e cient implementation of MPI on the Memory-Based Communication Facilities; Memory-Based FIFO is used for bu ering by the library, and Remote Write for comm...
On large distributed memory parallel computers the global communication cost of inner products seriously limits the performance of Krylov subspace methods 3]. We consider improved ...
