Another question, is it possible to, in a for-loop incrementing until it reaches a certain number, to have it loop again without incrementing? Just have it drop what it is doing when it reaches this command and start again at the same number it was at? I know I could make a while loop and just... (0 Replies)

Hello,
I've written a script to automate encoding of all the MP4 files in a directory (incl. subdirectories). But unfortunately it's running for the first MP4 file only.

mpi_group_compare
MPI_Group_compare(3OpenMPI)MPI_Group_compare(3OpenMPI)NAME
MPI_Group_compare - Compares two groups.
SYNTAX C Syntax
#include <mpi.h>
int MPI_Group_compare(MPI_Group group1, MPI_Group group2,
int *result)
Fortran Syntax
INCLUDE 'mpif.h'
MPI_GROUP_COMPARE(GROUP1, GROUP2, RESULT, IERROR)
INTEGER GROUP1, GROUP2, RESULT, IERROR
C++ Syntax
#include <mpi.h>
static int Group::Compare(const Group& group1, const Group& group2)
INPUT PARAMETERS
group1 First group (handle).
group2 Second group (handle).
OUTPUT PARAMETERS
result Integer which is MPI_IDENT if the order and members of the two groups are the same, MPI_SIMILAR if only the members are the same,
and MPI_UNEQUAL otherwise.
IERROR Fortran only: Error status (integer).
DESCRIPTION
MPI_IDENT results if the group members and group order is exactly the same in both groups. This happens for instance if group1 and group2
are the same handle. MPI_SIMILAR results if the group members are the same but the order is different. MPI_UNEQUAL results otherwise.
ERRORS
Almost all MPI routines return an error value; C routines as the value of the function and Fortran routines in the last argument. C++ func-
tions do not return errors. If the default error handler is set to MPI::ERRORS_THROW_EXCEPTIONS, then on error the C++ exception mechanism
will be used to throw an MPI:Exception object.
Before the error value is returned, the current MPI error handler is called. By default, this error handler aborts the MPI job, except for
I/O function errors. The error handler may be changed with MPI_Comm_set_errhandler; the predefined error handler MPI_ERRORS_RETURN may be
used to cause error values to be returned. Note that MPI does not guarantee that an MPI program can continue past an error.
