The firewall should already be solved. Basically, you have to define a
set of ports in your firewall that will let TCP messages pass through,
and then tell OMPI to use those ports for both the TCP BTL and the OOB.
"ompi_info --params btl tcp" - will tell you the right param to set
for the TCP BTL
"ompi_info --params oob tcp" will do the same for the OOB
Of course, that -does- leave a hole in your firewall that any TCP
message can exploit. :-/ You could look at more secure alternative
ways.
I'm not sure how to solve the NAT problem as it boils down to how to
specify the names/IP addresses of the nodes behind the NAT. Someone
who understands NATs better can help you there - I know there is a way
to do it, but I've never played with it.

Thank you Ralph and Samuel.
Sorry for the complete newbie question.
The reason that i wanted to study openMPI is because i wanted to
make open MPI support nodes that are behind NAT or firewall. If you
guys could give me some pointers on how to go about doing this i
would appreciate alot. I am considering this for my thesis project.
Sincerely,
LEO

openMPI (make "CFLAGS=-pg -g")
If you do a "./configure --help" you will get a complete list of the
configure options. You may want to turn on more things than just
enable-debug, though that is the critical first step.

Hi,
Let me begin by stating that I'm at most an Open MPI novice - but
you may want to try the addition of the --enable-debug configure
option. That is, for example:
./configure --enable-debug; make
Hope this helps.

Hi everyone,
I am trying to understand the openMPI code so was trying to enable
debug and profiling by issusing
$ make "CFLAGS=-pg -g"
But i am getting this error.

Is there any other way of enabling debugging and profilling in
open MPI.
