mpi.comm.maxsize
, mpi.request.maxsize
, and
mpi.status.maxsize
find the lengthes of comm, request, and status
arrayes respectively.
mpi.realloc.comm
, mpi.realloc.request
and
mpi.realloc.status
increase the lengthes of comm, request and
status arrayes to newmaxsize
respectively if newmaxsize
is
bigger than the original maximum size.
mpi.realloc.comm(newmaxsize)
mpi.realloc.request(newmaxsize)
mpi.realloc.status(newmaxsize)
mpi.comm.maxsize()
mpi.request.maxsize()
mpi.status.maxsize()
an integer.

When Rmpi is loaded, Rmpi allocs comm array with size 10, request
array with 10,000 and status array with 5,000. They should be enough in
most cases. They use less than 150KB system memory. In rare case, one can
use mpi.realloc.comm
, mpi.realloc.request
and
mpi.realloc.status
to increase them to bigger arrays.
