SHMEM_CACHE(3)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.
NOTES
These routines have been retained for improved backward compatability
with legacy architectures. They are not required on IRIX or Altix
systems, nor do they have any effect on cacheline states.
