<tt>Hi Matthew,<br>
<br>
Launching manualy ex19 shows only one process consuming cpu time,
after 952mn I've killed the job this morning.<br>

[begou@kareline tutorials]$ mpiexec -n 2 ./ex19 -snes_monitor<br>

top command shows:<br>

looks like the first process waiting for something that never
occur in MPI communication....<br>

<div>All make is doing is running ex19, which you can do
by hand. What do you get for</div>
