PCT 04/2014

Parallel Computational Technologies (PCT) 2014 was held on March 31st - April 4th, 2014 in Russia, Rostov-on-Don, Southern Federal University.

V.A. Bakhtin has proposed there a speaker paper:

GPU parallelization of the tests from NAS NPB3.3.1 using Fortran DVMH programming language

The paper presents a number of transformations applyed to the sequential NAS Parallel Benchmarks (NPB) of the 3.3.1 version  (EP, MG, BT, LU, SP) and the parallel execution specifications of these tests by the DVMH directives which are essential for their high performance execution on clusters with GPUs. We explore the impact of different parallelization options on the programs performance. The performance of the tests developed on a high-level language Fortran-DVMH (hereinafter FDVMH) are compared with their implementation on a low-level language OpenCL performed by researchers from Seoul National University.
