So you can get 16 cores in a 2U box with up to 128GB RAM - that's 8GB per core, not huge but is plenty for most apps. Comes with Solaris 10 installed but also will run Linux or Windows. You may not need a cluster if this config suffices, maybe just two of these boxes to manage instead of 5 or 10 of some others. (Obviously two 16-core systems is not equivalent to eight 4-core systems - which is "better" depends on how you'd use them.) The academic discounted price is fairly cheap if ordered minimally configured and then load it up with less expensive RAM - probably under $50K for two such systems. Anyway, it's another option to consider, which is what I'm doing. We currently have an Xserve (PowerPC) cluster and have been happy enough with it that we just bought another 9 Apple Xserves (8GB RAM each, 2 Intel Xeon dual-core processors in each 1U box so 36 cores total) and got a great price... a little over $50K, including extras like extended warranty, faster disks, etc. Although with Xserve you pretty much have to run OS X, which is fine unless some app you need doesn't come in an OS X binary and you can't get source to compile yourself. -- Lee Watkins, Jr. Director of Bioinformatics Center for Inherited Disease Research (CIDR) Institute of Genetic Medicine Johns Hopkins Bayview Research Campus 333 Cassell Drive, Triad Bldg.
