r1d207bb r5f42c27 1 1 2 FLEXPART VERSION 9.2.0(MPI)2 FLEXPART VERSION 10.0 beta (MPI) 3 3 4 4 Description … … 62 62 'numpart' are complemented by variables 'maxpart_mpi' and 'numpart_mpi' 63 63 which are the run-time determined number of particles per process, i.e, 64 maxpart_mpi = maxpart/ [number of processes]. The variable 'numpart'64 maxpart_mpi = maxpart/np, where np are the number of processes. The variable 'numpart' 65 65 is still used in the code, but redefined to mean 'number of particles 66 66 per MPI process' … … 79 79 But it is also possible that the 80 80 program will run even faster if the 4th process is participating in 81 the calculation of particle trajectories . This will largely depend on81 the calculation of particle trajectories instead. This will largely depend on 82 82 the problem size (total number of particles in the simulation, resolution 83 83 of grids etc) and hardware being used (disk speed/buffering, memory … … 120 120 FLEXPART-MPI is run with no (or just a few) particles, no performance 121 121 improvement is possible. In this case, most processing time is spent 122 in the 'getfields'-routine (ECMWF).122 in the 'getfields'-routine. 123 123 124 124 A) Running without dedicated reader process … … 173 173 * Nested wind fields 174 174 175 -The following will probably/possibly not work (untested/under developement):175 -The following will most probably not work (untested/under developement): 176 176 177 177 * Backward runs
