Hi Reuti,
I have done what you suggested and it WORKS with the wireless off
lcebaman@mac~/$ mpiexec -iface lo0 -n 4 ./hello Hello world from process 0 of 4 Hello world from process 3 of 4 Hello world from process 1 of 4 Hello world from process 2 of 4
What is the problem here then?

I have also noticed that working without any internet connection does not work either.
Just for curiosity:
$ mpiexec -iface lo0 -n 4 ./foo

Hi there,
I’ve got more news. The last IP that I showed in my last email it turns out that works OKAY, however now that I am back to the office and working on the wireless, it does not work. And that is the result of nslookup:
lcebaman@mac~/Projects/SPRINT$ nslookup localhost Server: 129.215.205.191 Address: 129.215.205.191#53
Name: localhost.ed.ac.uk Address: 127.0.0.1
lcebaman@mac~/Projects/SPRINT$ nslookup mac Server: 129.215.205.191 Address: 129.215.205.191#53
** server can't find mac: NXDOMAIN
Any thoughts?
Cheers, Luis

Here it is the output of those commands:
lcebaman@mac~/$ nslookup localhost Server: 192.168.1.1 Address: 192.168.1.1#53
Name: localhost Address: 127.0.0.1
lcebaman@mac~/$ nslookup mac Server: 192.168.1.1 Address: 192.168.1.1#53
Name: mac Address: 192.168.1.127
Is this a fixed address you get everytime? You could add it to /etc/hosts.
Interesting that MPICH throws an error about resolving "mac", although DNS is working.

Hi Pavan,
Yes, that is the output:
$ cat /etc/hosts ## # Host Database # # localhost is used to configure the loopback interface # when the system is booting. Do not change this entry. ## 127.0.0.1 localhost 255.255.255.255 broadcasthost ::1 localhost fe80::1%lo0 localhost
What is the output of:
$ nslookup localhost $ nslookup mac $ hostname
AFAICS your machine has no domainname, otherwise it would show up in the MPICH error message after "mac".
