[Beowulf] kernel tunning for HPC

Hi Richard:

   What type of workloads are running on the cluster, and more 
importantly, why do are you tuning it?  That is, what specific issue 
have you run into (poor performance or similar issues) that make you 
wish to tune?

   Additionally, what is the design of your system?  Single head node 
acting as a file server ?  Some other design?  What is your network 
architecture?  What is the type and nature of the loads and runs placed 
on the system?

   These would need to be answered before any reasonable tuning effort 
were undertaken.
