Hi Allan,<br>
I don't know if I understand your statement correctly. Are you saying
that you got Swift to be able to run MPI jobs on the BG/P? If yes, with
what provider? Coaster? Falkon? I don't think it was Falkon, as Falkon
doesn't have support for allocating jobs with N-processors. Does
Coaster support this kind of allocation, of multiple processors at the
same time? If yes, I'd like to hear more about this, and how you got
MPI to run on the BG/P through Swift.<br>
<br>
Thanks,<br>

echo $jobid
stat=`getstatus`

sleep 1
done

<pre wrap=""><!---->type file;
app (file out) hello() {
hello;

file output<"stdout.file">;
output = hello();
obviously we can't do stderr=@filename(x) and stuff, but we can still
get progress and restartability features of the output files we are
expecting. we would also need separate commandline processing for
"wrapper" args to real program args.
enjoy! :)
