disabled the firewall and using admin account so security isnt the issue here. like I said this problem only occurs when using a hostfile,  if I actually specify the hostname on the commandfline it works fine

Hi,

What's the firewall setting on the remote node? Could you try to add an exception for the application, or turn off the firewall completely?

When I specify the hosts separately on the commandline, as follows, the process completes as expected.

mpirun -np 8 -host remotehost,localhost myapp

Output appears for the localhost and a textfile is created on the remotehost

However when I use a hostfile the remote processes never complete. I can see the output from the local processes and by remote login I can see that that processes are being started on the remote machine but never complete.

The is a simple reduce example using boost.mpi (v1.43) I'm using windows 7 x64 pro on both machines and openmpi 1.4.2 the hostfile and athe app are in the same locaion on both machines.

Any idea why this is happening?
