For a detailed description of MPI Requirements see “Using ScaLAPACK Enhanced Routines” in the Introduction of this manual. |
This routine exits ScaLAPACK mode for the IMSL Library routines. All processors in the BLACS context call the routine.
Required Arguments
ICTXT — The BLACS context ID to which the processor grid is associated. (Input)
FORTRAN 90 Interface
Generic: CALL ScaLAPACK_EXIT (ICTXT)
Description
Subroutine ScaLAPACK_EXIT exits ScaLAPACK mode for the IMSL Library routines. The following actions occur when this routine is called:
BLACS_GRIDEXIT is called with the input BLACS context ID.The pointer to the grid ID, MP_PIGRID is nullified.If the grid, MP_IGRID, has been allocated, it is deallocated.MP_ICTXT is reset to its default value, HUGE(1).Published date: 03/19/2020
