There is a diskless OSCAR sub-project. I'm not directly involved with the project, so I can't comment on its status; perhaps someone involved with the effort can. >This of course would increase load on the head node, and add more >traffic to the network, but would it be worthwhile as an option to add >to oscar? Or is it a horrible idea for clusters in general? Of course, the answer is "It Depends." More specifically, it depends on the application you're running, the network and inter-node traffic, the non-scratch disk activities, and other factors. Some applications run quite well on diskless clusters, others run horribly. While maintenance of a diskless cluster is generally easier than its diskful cousin, you should always be mindful of the fact that the computations being performed on the cluster should be the significant design factor, not the ease of administration. So, only you, or someone who has carefully studied the same workflow and application usage as you will be running, can accurately answer this question. -- David N.
