Hi.i'm a user of the Ubuntu Linux OS, and also a packager for this OS.As you may know , packaging can be take a lot of time, mainly during building process.I would create a public cluster for help packagers. All Ubuntu users can accept we use their computers on the cluster. But the cluster system M
Hi Bruce,
Do you have any idea what the performance impact from enabling scrubbing
is on your systems? did you do any before/after benchmarking?
Thanks,

Hi,
Sure. We have a head node which acts as an NFS server for the diskless
compute nodes in the cluster. On the head node, I had to use the
following BIOS settings to ensure the OS could see the full 4GB of

We, at LFC, have some specific requests, and our cluster is not large (much less powerfull than yours, a bunch of old PIII), so we use debian stable as OS, MPICH 1.2.7 as Message Passing Libraries, Portland Group Compilers and Intel Compilers, and netlib lapack and scalapack. We also use ACML with
