The head node will not.
The compute nodes will have the Myri-10G cards. The disks on the compute nodes will make up a PVFS2 file system. The compute nodes will also be PVFS2 clients. Data on this file system will consist of raw output from calculations. The data files will not be immediately deleted but they will not be backed up either. Users are expected to save post-processing files in the home directory on the head node. The head node does not have a Myri-10G card. I would like to be able to mount the PVFS2 file system on the head node via Ethernet (Gb) if that is possible. I guess what I am not sure about is if I can use the MX bmi for the I/O servers and clients on the compute nodes and TCP for the client on the head node. > You want a PVFS2 filesystem for storage for this cluster.
