Benoit des Ligneris, Ph.D, is a postdoctoral fellow at the polytechnique school of Montreal and a researcher in the Scientific Computing Center of the Universite de Sherbrooke. He is a core-member of the OSCAR (oscar.openclustergroup.org) and the chair of the thin-OSCAR workgroup dedicated to high performance diskless computing.
While OSCAR (Open Source Cluster Application Resource) has been conceived for
clusters with disks since its very first version, diskless and systemless
support was a feature that a lot of people expected. The Center for
Scientific Computing has built several clusters without disks; we tested
OSCAR and were easily convinced of its quality, especially when compared to
our own homemade scripts. We decided to use OSCAR for our diskless cluster
and then transfer our diskless expertise to the OSCAR project. The thin-OSCAR
workgroup was created specifically to analyze and solve problems that arise
while adding this diskless cluster support.
This article first defines essential notions for a diskless cluster. The
actual implementation of thin-OSCAR is explored, along with a road... (more)
