im really desperate now... ok now its running, but somehow it doesnt
wait for the input but instead the ring example keeps looping a very
big number (but it seens like the 0 node doesnt send anything)... can
you help me out a lil more?
also, is there a way to send an array? or at least part of it?
one last doubt: if i send two msgs to a node with mpi_isend (async),
will it stack on a queue? or will it return an error code?
