blacsexit {pbdBASE} | R Documentation |
Shuts down all BLACS communicators.
base.blacsexit(CONT = TRUE) blacsexit(CONT = TRUE)
CONT |
logical; determines whether or not to shut down all MPI communicators |
If the user wishes to shut down BLACS communicators but still have access to
MPI, then call this function with CONT=TRUE
. Calling
blacsexit(CONT=FALSE)
will shut down all MPI communicators,
equivalent to calling
> blacsexit(CONT=TRUE)
> finalize(mpi.finalize=TRUE)
This function is automatically invoked if BLACS communicators are running
and finalize()
is called.
Has an invisible return of 0 when successful.
