The Sun Compute Cluster currently uses SLES10 as the OS of choice for the compute nodes. Working on the software stack for the solution, I'm currently looking for more information on tuning the performance of SLES10. Of course the first step is to turn off the unnecessary services that a typical compute node will not require. I took a look at a freshly installed server with the default installation settings and found these services that are running which I think can be safely turned off:
I would also change the default runlevel to 3 to prevent starting up of X. If anyone has other suggestions or tuning guide, please do let me know!
