Well yes, the job runs on host2 locally, but parallel execution does the same thing like on host1. Someone here said that if all the computers have the same ip direction it won't work.. Well, every node has 127.0.1.1 As ip, and all of them had same host name till I changed the two of them. Hydra is the default launcher. I also forgot to mencione that ping host2 and same, ping host1 works fine... Sent from my BlackBerry 10 smartphone.

Hi. I'm not sure how it's done on that version of mpich, but you need to be sure that the mpd daemon is running on both hosts (mpdboot or maybe mpiexec starts it ).
No. The `mpdboot` is gone for some time - nowadays Hydra is used (since MPICH2 v1.3). -- Reuti
Does cpi runs in hosts 2 locally?

Hey there, I am trying to set up a parallel invironment with 14 machines, running Linux XUbuntu, connected via ethernet. They all have same IP's and same hostnames. Well I started installing mpich-3.0.4 on a single machine, I run the cpi example on localhost by giving mpiexec -host localhost -n 4 ./examples/cpi and everything worked fine! So I continued changing the hostnames of 2 pc's for a start, and setting up the ssh in these two, also I installed the mpich-3.0.4 on the other machine too. By giving the ssh <othermachine> date commant , I get the date of the other host without giving a password, so I think I passed that step too. Next step was to check if the mpich-3.0.4 runs parallel, so I created a machine file (I made a text file giving the hostnames of the two computers , host1 and host2), and save it in my mpich-3.0.4 build directory. Though when I am trying to parallel run the cpi code by giving mpiexec -n 4 -f machinefile ./examples/cpi on my working directory, I get NO errors but neither parallel job... All processes still running on host1 which is my work station. What am I doing wrong? Thanks
