wait {pbdMPI} | R Documentation |
The functions call MPI wait functions.
wait(request = .pbd_env$SPMD.CT$request, status = .pbd_env$SPMD.CT$status) waitany(count, status = .pbd_env$SPMD.CT$status) waitsome(count) waitall(count)
request |
a request number. |
status |
a status number. |
count |
a count number. |
These functions are for internal uses. Potentially, they wait after some nonblocking MPI calls.
An invisible state of MPI call is returned.
