shmem_clear_cache_inv(3), shmem_set_cache_inv(3), shmem_set_cache_line_inv(3),
shmem_udcflush(3), shmem_udcflush_line(3) - Controls data cache utilities
C or C++:
#include <mpp/shmem.h>
void shmem_clear_cache_inv(void);
void shmem_clear_cache_line_inv(void *target);
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_CLEAR_CACHE_LINE_INV(target)
CALL SHMEM_SET_CACHE_INV
CALL SHMEM_SET_CACHE_LINE_INV(target)
CALL SHMEM_UDCFLUSH
CALL SHMEM_UDCFLUSH_LINE(target)
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_clear_cache_inv disables automatic cache coherency
mode previously enabled by shmem_set_cache_inv or shmem_set_cache_line_inv.
shmem_clear_cache_line_inv disables automatic cache coherency mode for
the cache line associated with the address of target only.
shmem_set_cache_inv
enables the OpenSHMEM API to automatically decide the best strategy for
cache coherency.
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.
These routines have been retained
for improved backward compatability with legacy architectures.
