Reuti, yes, if I ask which hydra_pmi_proxy, they all three point to the same location (accessible via nfs mounted drives). Cheers, Ron On 1/03/2014 21:29, Reuti wrote:

Gus and others, many thanks for your comments and suggestions. I am unsure whether I need fortran included as I am not in control of the software to be run on this linux cluster. I have asked but not yet got a reply...

However, I did a yum search gfortran and installed the gcc-gfortran.x86_64 (I hope that was the one you referred to). I followed up with the ./configure ... as per your suggestion. That did not work. I then tried with only ./configure --prefix=/my/bin/folder. That worked so I also did make and make install.

I have a machinefile with three linux computers, all sharing the same mpi binaries. Running hostname on all 20 cores works, so I guess I should conclude that mpi works, right? Are they using the same binaries /my/bin/folder for a non-interactive startup too, i.e.:

$ ssh sargeant which hydra_pmi_proxy

returns the same as on the master (maybe ~/.bashrc needs to set the $PATH)?
