<div style="direction: ltr;font-family: Tahoma;color: #333399;font-size: 10pt;">Hi,<br>
<br>
In my program I have a loop of this form:<br>
<br>
loop {<br>
MPI_Send(small message)<br>
MPI_Isend(big message)<br>
}<br>
do_some_computation()<br>
MPI_Waitall<br>
<br>
The sends and isends all have the same target rank.<br>
<br>
Is there a risk that an MPI_Send forces a previously posted MPI_Isend to complete before it can complete itself (in which case I would loose the benefit of using non-blocking sends)?<br>
<br>
Thanks,<br>
<br>
Matthieu<br>
