Subject: Re: [OMPI users] MPi Abort verbosity

I've successfully installed openMPI on other PC. But when I tried to install it
on my laptop and typed 'mpicc' , the response was:
 
The program 'mpicc' can be found in the following packages:
 * lam4-dev
 * libmpich-mpd1.0-dev
 * libmpich-shmem1.0-dev
 * libmpich1.0-dev
 * libopenmpi-dev
 * mpich2
Try: sudo apt-get install <selected package>
mpicc: command not found
chao_at_ubuntu:~$ sudo apt-get install libopenmpi-dev
[sudo] password for chao:
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Couldn't find package liopenmpi-dev

Of course I'm connected to the internet. Please help..

Don't know if this would work, but why not doing what follows:
1. set a signal handler in your application. This where you would do
your cleanup.
2. call your application with an mpi_abort_delay set to a value > 0 (0
is the default value). This should delay the actual procs abort.
3. During that delay, and after you see the message about process going
to abort, send the signal that should be caught in #1.

But may be I'm wrong, as I told you I've never tested that...

Nadia
