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_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.
NOTES
These routines have been retained for improved backward compatability with legacy architectures.
