Hello,
I am Computer Engineering student and I trying to assemble a cluster that running with TELEMAC. However I'm having difficult to compile TELEMAC and the cluster together.
In this cluster, I use network shared by nfs on ubuntu 12:04. I created a Hostfile file in / opt / hostfile with node names, but can not run.
In attached is my .cfg.
Someone can help me, please?

thank you.

Hello,

A couple of comments:
- if you can, although not essential, I would try using mpiexec rather than mpirun
- mpi_hosts should include a list of host names, space delimited. It does does not have to match the number of processor used -- the setup will loop through the list of host to associate hosts, even if you have one (automatically duplicating the same host name for all processes). Therefor you should have something like -machinefile <hostfile> in your runmpi command. However, since you set the hostfile in the runmpi command (without reference to <hostfile>) it does not matter in your case. What you did is just as valid.
- You need hpc_cmdexec to run the command qsub < <hpc_stdin> where <hpc_stdin> is replace by the content of hpc_stdin. Please uncomment this. As you can see in your case, the mpirun command is launched but not the HPC queue command.

Hope this helps,
Sébastien.

Dear Sébastian,
Thank you for your answer. I've tried what you suggested,but occur this error "qsub not found". For this reason, I commented this line. After your observation I remember that it do the process line. I'm sending my .cfg with alteration. I hope you can help me.
Regards,
Daniel
