8. 25 September 2007eSDO and the VO, ADAss 2007Elizabeth Auden MPI NLFFF on NGS NLFFF calculations involve some nasty triple integrals; great speed gains to be had from parallelization. The eSDO NLFFF algorithm can be run on a single CPU (8 hours for a 64 3 pixel vector magnetogram) or on parallel machines using MPI-CH2 implementation. 2007 time trials of eSDO NLFFF algorithm on NGS servers (using MPI- CH optimized for NGS) show similar performance to OpenMPI implementation OpenMPI version likely to be used in SDO processing pipeline (closed access); MPI version can be used by any UK academic with an e- Science certificate. Cheat sheet: MPI: Message Passing Interface – standard used to create parallel applications NLFFF: Non-linear force-free field – method of extrapolating magnetic fields NGS: National Grid Service – high performance computational facilities for UK researchers
