Juergen,

I see that your Matterhorn Cluster uses AMD Opteron dual processors. This is fine (we use the same processor in our cluster, along with Athlons and newer Xeons).

However, I do not see which OS is used in your cluster. Freesurfer supports most of the Linux OS's, and so I do not foresee any insurmountable problems for running Freesurfer on your cluster.

Per another mailing list thread, Freesurfer does not currently run in a fine-grained parallel manner (that is, it is not multi-threaded). But clusters are regularly used to process one subject per node, thus a group of subjects can be processed 'in parallel'.

Dear Freesurfer user

because Freesurfer is so processor and memory intensive, we intented to run Freesurfer parallely on a supercomputer (called Matterhorn Cluster http://www.id.unizh.ch/dl/wissrechnen/HPC-Supercomputing-Main.html).

Does Freesurfer is able to run on such a machine without modifying it? What are potential problems that could occur?

Thanks in advance Best regards Juergen
