The very first time I booted the nodes, they were not accessible from the master, and after activating the requested nodes I had to reboot them physically. Some of the scripts (which most of them are invoked through the main command perceus) have some minor imperfections with the access rights for non-root users to the perceus databases.

We built a cluster in the Fall 08<br /> semester using perceus and the students had a great<br /> experience...as did I. We experimented with running<br /> both control and data networks to the compute nodes<br /> and that worked fine with some changes to the<br /> ipadrr module. Students were able to write programs<br /> using openmpi. As a system to let students build<br /> and program a cluster, perceus is excellent.<br /> We started the semester with one version and midway<br /> through the semester we did an upgrade. I want to<br /> thank Greg Kurtzer and his team for developing<br /> a cluster management system that works so well. I<br /> also commend Jeff Layton on his articles on perceus.<br /> The article in mid-2008 brought perceus to my<br /> attention and after working with it during the <br /> summer or 2008 I decided to use it in my cluster<br /> class in the fall 08 semester.
