Beowulf list readers: I have a Beowulf cluster (12 diskless nodes, 1 fileserver/master) with 26 processors (total) that is configured to run computational simulations in both parallel and serial (pretty standard for this list). I am interested in utilizing my cluster to run a series of serial g98 calculations on each node. These calcualtions (as many of you know) require a "scratch" space. How can this scratch space be provided to a diskless node? Here are a few options that I have identified. 1). Mount a LARGE ram drive? (1GB in size if possible??) 2). Install hard disk drives in each of the slave nodes? (unattractive) 3). Use a drive mounted via NFS/PVNFS? (large amount of communication) Has anyone encountered this? If so...what was the workaround that was implemented? I am open to any suggestions and comments. :) Thanks, Mathew Lee Research Assistant Mechanical and Aerospace Engineering Oklahoma State University
