.SH DESCRIPTION
|
|
|
|
The following argument is passed to the cache line control routines:
|
|
.TP
|
|
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.
|
|
.PP
|
|
\fBshmem_clear_cache_inv\fP
|
|
disables automatic cache coherency mode previously
|
|
enabled by shmem_set_cache_inv or shmem_set_cache_line_inv.
|
|
.PP
|
|
\fBshmem_clear_cache_line_inv\fP
|
|
disables automatic cache coherency mode for the
|
|
cache line associated with the address of \fBtarget\fP
|
|
only.
|
|
.PP
|
|
\fBshmem_set_cache_inv\fP
|
|
enables the OpenSHMEM API to automatically decide the
|
|
best strategy for cache coherency.
|
|
.PP
|
|
\fBshmem_set_cache_line_inv\fP
|
|
enables automatic cache coherency mode for the
|
|
cache line associated with the address of \fBtarget\fP
|
|
only.
|
|
.PP
|
|
\fBshmem_clear_cache_inv\fP
|
|
disables automatic cache coherency mode previously
|
|
enabled by shmem_set_cache_inv or shmem_set_cache_line_inv.
|
|
.PP
|
|
\fBshmem_udcflush\fP
|
|
makes the entire user data cache coherent.
|
|
.PP
|
|
\fBshmem_udcflush_line\fP
|
|
makes coherent the cache line that corresponds with
|
|
the address specified by target.

.SH NOTES
|
|
|
|
These routines have been retained for improved backward compatability with legacy

|
architectures.
