The most common reason for this problem is that the ompi_info command can't be found in your path. This is complicated because not only are your paths on the local and remote systems usually different, but Eclipse obtains its paths from different places depending on how it is launched. Here are some things you can do:
1. Run the command "ssh remote_host ompi_info -a --parseable". If this works, then your shell paths are correct. If not, then you probably need to change your path on the remote system.
2. If you're having problems using Open MPI installed on the local machine, start Eclipse from a shell so that it picks up the correct paths. If this works and you want to launch Eclipse from the window system, you need to find out how to change the path. This is usually NOT the same as setting the PATH variable in your bash_profile.
3. If you're still having problems, on the Open MPI tool configuration page of the resource manager configuration wizard, uncheck "Use default location" and enter the path of the directory containing ompi_info (e.g. /usr/local/bin).
Hope this helps,
