<div>
<div>Hi,</div>
<div><br>
</div>
<div>I am trying to parse the command line global options for mpirun in the main section of my C program. For example, when I run:</div>
<div><br>
</div>
<div>mpirun -np 2 -machinefile hostfile ./myprogram 100</div>
<div><br>
</div>
<div>I would like to parse the seven arguments instead of these two only: "./myprogram" and "100". </div>
<div><br>
</div>
<div>I tried to parse the arguments before the MPI_Init call but at this point I already got only two arguments, I guess the mpirun executable "eats" the MPI specific arguments. I can't find the way to do that.</div>
<div><br>
</div>
<div>Thank you in advance,</div>
