## Release the Process Grid

After the desired computation on a process grid has been completed, it is advisable to release the process grid via a call to BLACS_GRIDEXIT . When all computations have been completed, the program is exited with a call to BLACS_EXIT.

A typical code fragment to accomplish these steps would be

          CALL BLACS_GRIDEXIT( ICTXT )
          CALL BLACS_EXIT( 0 )

A detailed explanation of the BLACS calling sequences can be found in Appendix D and [54].
