NAME

MPI_Pcontrol - Hook for profilers

SYNOPSIS

#include <mpi.h> 
int MPI_Pcontrol(const int level , ...); 
#include <pmpi.h> 
int PMPI_MPI_Pcontrol(const int level , ...); 

INPUT PARAMETER

level - profiling level (integer)

DESCRIPTION

The MPI_Pcontrol() function is designed to be used as a convenient hook for user code to control a profiler. The profiler should override this function. The interpretation of level and any other parameters is left up to the profiling library code.

PMPI_Pcontrol() is the profiling version of this function.

ERRORS

All MPI routines except for MPI_Wtime and MPI_Wtick return an error value. The the current MPI error handler is invoked if this return value is not MPI_SUCCESS. The default error handler aborts, but this may be changed with by using the MPI_Errhandler_set() function. The predefined error handler MPI_ERRORS_RETURN may be used to cause error values to be returned instead. Note that MPI does not guarentee that an MPI program can continue past an error. In this implementation, all errors except MPI_ERR_INTERN or MPI_ERR_OTHER should always be recoverable.

MPI_SUCCESS - No error.
