       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 compatibility with legacy architectures.
