41 | .SH DESCRIPTION |
---|
42 | .ft R |
---|
43 | Since Open MPI is MPI 2.0 compliant, this function will return a version value of 2 and a subversion value of 0 for this release. |
---|

---|
45 | .SH NOTE |
---|
46 | .ft R |
---|
47 | MPI_Get_version is one of the few functions that can be called before MPI_Init and after MPI_Finalize. |
---|
48 | |
---|
49 | .SH ERRORS |
---|
50 | Almost all MPI routines return an error value; C routines as the value of the function and Fortran routines in the last argument. C++ functions 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. |
---|
51 | .sp |
---|
52 | Before the error value is returned, the current MPI error handler is |
---|
53 | 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. |
