shmem_cache(3)

NAME
     shmem_clear_cache_inv, shmem_set_cache_inv, shmem_set_cache_line_inv,
     shmem_udcflush, shmem_udcflush_line - Controls data cache utilities

SYNOPSIS
     C or C++:

        #include <mpp/shmem.h>

        void shmem_clear_cache_inv(void);

        void shmem_set_cache_inv(void);

        void shmem_set_cache_line_inv(void *target);

        void shmem_udcflush(void);

        void shmem_udcflush_line(void *target);

     Fortran:

        INCLUDE "mpp/shmem.fh"

        CALL SHMEM_CLEAR_CACHE_INV

        CALL SHMEM_SET_CACHE_INV

        CALL SHMEM_SET_CACHE_LINE_INV(target)

        CALL SHMEM_UDCFLUSH

        CALL SHMEM_UDCFLUSH_LINE(target)

DESCRIPTION
     The following argument is passed to the cache line control routines:

     target    A data object that is local to the processing element (PE).
               target can be of any noncharacter type.  If you are using
               Fortran, it can be of any kind.

     shmem_set_cache_inv enables automatic cache coherency mode.

     shmem_set_cache_line_inv enables automatic cache coherency mode for
     the cache line associated with the address of target only.

     shmem_clear_cache_inv disables automatic cache coherency mode
     previously enabled by shmem_set_cache_inv or shmem_set_cache_line_inv.

     shmem_udcflush makes the entire user data cache coherent.

     shmem_udcflush_line makes coherent the cache line that corresponds
     with the address specified by target.
