I am missing something.
By default bash sources a file .bashrc if one exists in the current working for each "new" bash invocation. The same is true for ~.kshrc. Each "new" invocation of ksh sources the .kshrc file in the current working directory if it exists.
Per the man pages for each shell.
An example new: executing a script that has a shebang: #!/bin/bash, same for ksh
So why write a script which does exactly what default behavior of your shell already does for you? Good shell coding practice is to place a shebang on the first line, so it is clear what envoronment the shell requires. If bash is not in the PATH then #!/bin/bash will fail which is what you want.

mpi_type_set_attr
MPI_Type_set_attr(3OpenMPI) MPI_Type_set_attr(3OpenMPI)
NAME
MPI_Type_set_attr - Sets a key value/attribute pair to a data type.
SYNTAX
C Syntax
#include <mpi.h>
int MPI_Type_set_attr(MPI_Datatype type, int type_keyval,
void *attribute_val)
Fortran Syntax (see FORTRAN 77 NOTES)
INCLUDE 'mpif.h'
MPI_TYPE_SET_ATTR(TYPE, TYPE_KEYVAL, ATTRIBUTE_VAL, IERROR)
INTEGER TYPE, TYPE_KEYVAL, IERROR
INTEGER(KIND=MPI_ADDRESS_KIND) ATTRIBUTE_VAL
C++ Syntax
#include <mpi.h>
void MPI::Datatype::Set_attr(int type_keyval, const void* attribute_val)
INPUT
/OUTPUT PARAMETER
type Data type to which attribute will be attached (handle).
INPUT PARAMETERS
type_keyval
Key value (integer).
attribute_val
Attribute value.
OUTPUT PARAMETER
IERROR Fortran only: Error status (integer).
DESCRIPTION
For the given data type, MPI_Type_set_attr sets the key value to the value of the specified attribute.
FORTRAN 77 NOTES
The MPI standard prescribes portable Fortran syntax for the ATTRIBUTE_VAL argument only for Fortran 90. FORTRAN 77 users may use the non-
portable syntax
INTEGER*MPI_ADDRESS_KIND ATTRIBUTE_VAL
where MPI_ADDRESS_KIND is a constant defined in mpif.h and gives the length of the declared integer in bytes.
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.
