Hello Terry,
I have installed 1.2.7 and I obtain the same result.
I will explain you what I have done.
1. On my computer edu@10.1.10.240 I have added a new user called sofia. This
way I have sofia@10.1.10.208 and sofia@10.1.10.240.
2. I have downloaded the openmpi 1.2.7 from the openmpi website on both
computers in /home/sofia/Desktop.
3. I have installed everything using "sudo ./configure", "sudo make" and
"sudo make install".
4. To make ssh not ask me for a password. I have typed in sofia@10.1.10.208
"ssh-keygen -t dsa", "cd $HOME/.ssh" and "cp id_dsa.pub authorized_keys". I
have copied the directory "/home/sofia/.ssh" from sofia@10.1.10.208 to
/home/sofia/.ssh in sofia@10.1.10.240. The ssh command without password
works on computer sofia@10.1.10.208 but computer sofia@10.1.10.208 ask me
for a passphrase and for the password. Is it normal?
5. I have created a directory "/home/sofia/programasparalelos" on both
computers and I have given permissions to the directory with "chmod 777".
6. I have copied on both computers in "/home/sofia/programasparalelos" the
program "PruebaSumaParalela.c" (I have changed a little bit the program, I
enclose you the new program) and I have compiled using "mpicc
PruebaSumaParalela.c -o PruebaSumaParalela.out".
7. Now I run the program on both computersusing the command:
mpirun -np2 --host 10.1.10.208,10.1.10.240 --prefix /usr/local
./PruebaSumaParalela.out
When I run the program I obtain 3 PIDs executing on every computer, 2 of
"./PruebaSumaParalela.out" and 1 of "mpirun -np2 --host
10.1.10.208,10.1.10.240 --prefix /usr/local ./PruebaSumaParalela.out". I
enclose you the results obtained on every computer for every
"./PruebaSumaParalela.out".
Thank you very much.
Sofia

Turns out you debugged the mpirun I was actually wanting you to attach to
your program, PruebaSumaParalela.out, on both nodes and dump each of their
stacks.
Is there a reason why you are using 1.2.2 instead of 1.2.7 or something
from the 1.3 branch? I am wondering if maybe there is some sort of bug in
the tcp BTL that is preventing it from matching your two interfaces.
Another thing to try is to specifically list out the interfaces you want
to have used. I do not think this is going to help but it can't hurt
either. I would do something like:
mpirun -np 2 --host 10.4.5.123,edu@10.4.5.126 --mca mpi_preconnect_all
1 --prefix /usr/local -mca btl self,tcp -mca btl_tcp_if_include eth1
./PruebaSumaParalela.out
--td

Hello Terry,
Finally, I have installed dbx. I enclose a file with the result that I get
when I type "dbx - PID of mpirun..." and then "where" on computer
10.4.5.123 .
Do you have any idea what could be the problem?
Thanks a lot!!
Sofia
