<DIV><FONT face=Arial size=2>Hi all,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>When using mpich1 with mpirun I used to put some
getchar() in my code for debug purpose.</FONT></DIV>
<DIV><FONT face=Arial size=2>Then during computation I had to hit "enter" Nproc
times.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I wonder why when using mpiexec (I use mpich2
1.0.4), if I do the same my code freeze and I can't go on.</FONT></DIV>
<DIV><FONT face=Arial size=2>To obtain the same behaviour I write now:
</FONT></DIV>
<DIV><FONT face=Arial size=2>If (mytid ==0)
getchar();MPI_Barrier(MPI_COMM_WORLD);</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Thanks,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Regards,</FONT></DIV>
