I have an HPC including a server and about 20 diskless computing nodes. The server has a swap partition. I wonder if I could use this swap partition over network (ie. using NFS) to be used by computing nodes. I know this would cause serious speed reduction, but as nodes need small amount of swap for just some seconds, it worth to use this strange type of swapping.
P.S: nodes don't have HDD and they have the maximum supported memory(RAM).
