[Beowulf] kernel tunning for HPC

[Richard Miguel San Martín]

Hi all, 

I have a Red hat EL v3 system that i use as head node of a cluster, I want to 
do tunning of kernel for HPC. The question is how and what values i must 
change for to do it.

I was trying of change sysctl values but im not sure if that is ok. Where i 
can obtain information about that?.

Thanks in advance
