You might want to take this question over to the Beowulf list -- they talk a lot more about cluster configurations than we do -- and/or the mm4 and wein2k support lists (since they know the details of those applications -- if you're going to have a cluster for a specific set of applications, it can be best to get input from the developers who know the applications best, and what their communication characteristics are).
