CALL SHMEM_SET_CACHE_LINE_INV(dest)
CALL SHMEM_UDCFLUSH
CALL SHMEM_UDCFLUSH_LINE(dest)

Arguments

dest        A data object that is local to the PE.  dest can be of any
            noncharacter type. When using Fortran, it can be of any kind.

Description

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 dest 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 dest.

Return Values

None.

Notes

These routines have been retained for improved backward compatibility with
legacy architectures.  They are not required to be supported by implementing
them as no-ops and where used, they may have no effect on cache line
states.

Examples

None.
