Hi all,

A problem with MPI_Isend. After I post an MPI_Isend request to a receiving
node, may I use MPI_Isend to post another one to the same node before it has
been ensured that the receiver has received the previous message? In the
parameters of MPI_Isend, I used different sending buffers. But it seems that
the first message has not been received by the first one sometimes. I checked
the MPI tutorial but still unclear about it.

Thank you,
Guanhua
