MACS2

MARSIS coherent surface clutter simulator

SET-UP:

To use OpenMP set #define OMP 1 in setParallel.h To use MPI set #define MPI 1 in setParallel.h

OpenMP and MPI can be used simultaneously.

To compile for big endian machines set #define BIG_ENDIAN_COMP 1 in marsislib.h line 65

Select the complex variable error function algorithm by setting #define MARSIS_erf_alg in marsislib.h line 54

COMPILATION:

Example using gcc:

Serial

gcc main.c marsislib.c faddeewa_w.c -lm -O3 -o macs

OpenMP:

gcc main.c marsislib.c faddeewa_w.c -lm -O3 -fopenmp -o macs

MPI:

mpicc main.c marsislib.c faddeewa_w.c -lm -O3 -o macs

MPI+OpenMP

mpicc main.c marsislib.c faddeewa_w.c -lm -O3 -fopenmp -o macs

RUN:

macs -m <path_to_MOLA_dir> -i <path_to_intput_file> -o <output_file>

Number of used nodes, number of OpenMP threads etc. defined by the scheduler job configuration file.
