I suspect (with little supporting evidence) that this is partly due to the different ways people are using clusters in diverse applications. For instance, a lot of the academic work is directed at microdecomposition via message passing, distributed shared memory or what have you. We on the other hand are currently doing some environmental modelling work characterised by large numbers of 30hr runs of a fat nasty FORTRAN program on assorted datasets. Clusters are appropriate in both cases, but different infrastructures are appropriate. One indicator I don't much like is that there doesn't seem to be much cluster-related software among the thousands of ports in the ports collection. -- Bob Bishop +44 (0)118 977 4017 rb@gid.co.uk fax +44 (0)118 989 4254 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-cluster" in the body of the message
