This platform can be used to solve efficiently mathematically\nheavy problems. Running programs in parallel computing environment differs from running programs in serial environment. In order to achieve speedup from parallel environment, programmer must use programming methods suitable to parallel environment. In this work we explain some basics of parallel computing and examine how pro-gramming and optimization practices affect programs running in graphics processing unit. We also created our own theoretical parameterized model which is used to estimate performance of our GPU-programs. Our model is used to estimate performance of two different matrix multiplication programs, which are run in parallel environment. In results we compare theoretical performance values, calculated by using our own model, to ones measured in real run environment. Also we present how different parameters affect to gained speedup when using our GPU-programs.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted using Plone Publishing form by Jari Isohanni (jaanisoh) on 2013-11-26 12:31:14.734042.
