NAME¶

ffindex_apply_mpi: - apply a program to each FFindex entry (mpi enhanced)

DESCRIPTION¶

ERROR Not enough arguments.

USAGE: ffindex_apply_mpi [-m] [-q] [-l LOG_FILE] -d DATA_FILENAME_OUT -i INDEX_FILENAME_OUT DATA_FILENAME INDEX_FILENAME -- PROGRAM [PROGRAM_ARGS]*

-l

LOG_FILE like an FFindex file but with the return value of apply added. This file can be processed and used as FFindex file. E.g. grep " 1$" foo.log | cut -f 1-3 > foo-special.ffindex. where maybe the ffindex_apply_mpi ran with -- perl -e 'return 1 if(/^SPECIAL/)'

-m

Do not merge the FFindex parts generated by the different MPI processes This is useful for large MPI Jobs where merge time might be accounted.

-d

FFDATA output file, stdout of program will be captured

-i

FFINDEX output file, entries get the same name as input entry
