Hi all
We are designing a new HPC system for our lab. We are shifting ideas
around (our budget is of 30K euro).
We do CFD and mainly run two types of stuff:
- Finite volume, with neighbour (hallo cell) comunication (so,
communication with neighbours only)
- Direct Numerical Simulation
I manage a small cluster with a central image for the execution hosts
(fully decoupled from the master/ login nodes). To deal with direct
access to nodes:
- Every user has an "*" on the password field of the /etc/shadow file
in the execution hosts images
- Access through ssh to the exec hosts is

Greetings,
I'm using gridengine (6.2u4, open source ver.) and I would like to use
the Modules software. Modules uses a shell function that must be
exported (bash: "export -f func_name" in order to set environment
variables), but gridengine has a bug related with bash exported
functions[1].

The cluster is a Debian based beowulf-like cluster (we have supplied

Greetings,
I relatively new to cluster environments and I was given a small
(7nodes+1head) cluster to admin. So far I only had to maintain what
was already installed so few problems to solve (and to think on). But
new (diferent: amd opteron vs intel xeon) machines came and I have to
