Massive Parallel Programing (MPP) of kMC a) with CPU cores (multi-core CPUs, LINUX clusters,…) b) with graphic cards (NVIDIAs Tesla and Fermi card, ATI,…) BEDMOD Workshop, March 26 - 29, 2012, Dresden 22 Member of the Helmholtz Association Karl-Heinz Heinig | Institute Ion-Beam Physics and Materials Research | http://www.hzdr.de
Massive Parallel Programing (MPP) of kMC with CPU cores “Dead borders” concept: Break the simulation cell (periodic BCs) into sub-domains Run kMC simulations of the sub-domains in parallel Avoid “talking” between sub-domains by “dead borders” (small statistical error) After a “short” time, shift the global origin randomly other dead borders 2D example simulation cell BEDMOD Workshop, March 26 - 29, 2012, Dresden sub-domain dead border global origin 23 other dead borders new sub-domains new global origin Member of the Helmholtz Association Karl-Heinz Heinig | Institute Ion-Beam Physics and Materials Research | http://www.hzdr.de
