Message-ID: <20000302092927.A73201@symbion.srrc.usda.gov> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii X-Mailer: Mutt 1.0.1i Sender: owner-freebsd-cluster@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG I am currently using FreeBSD-3.4 with clusterit-1.3 on a small 4 node cluster. I have mpich and pvm installed for parallel programs. I need to expand the capabilities of this cluster and add another 12 nodes to it. I do not think that the current tools I have (clusterit and GNQS) can meet the needs I have. The parallel part of the cluster is not a problem but I need to set it up for High Throughput Computing as the majority of the jobs are single processor jobs, but there are a lot of them. The availability of the cluster will also be widened to include other users at my facility besides myself. This means that a cluster that presents itself to the user as a single machine would be beneficial. Also, there will be some nodes on the cluster that will be in and out of the cluster as they are called upon for other needs periodically so the ability to move jobs between nodes is important. In my Internet search on this topic I have concluded that I need something like MOSIX or Condor or a fairly sophisticated batch queuing system like PBS or maybe DQS. My preference would be MOSIX but of course it is only available for Linux, as is Condor. I looked into Treadmarks but I do not think that would be the best tool. I came across some references to something that Sarnoff had done but all of the links to it are stale and therefore I could not really get any useful information on that. Can anyone provide any information on what is possible with FreeBSD as related to High Throughput Computing with good cluster management software? I would be willing to sacrifice some "ease of use" features in the cluster management software if it meant that I would not have to switch to Linux.
