2 – InfiniPath Cluster Administration Performance and Management Tips

Q

nodes. Since these are presumed to be specialized computing appliances, they do not need many of the service daemons normally running on a general Linux computer.

Following are several groups constituting a minimal necessary set of services. These are all services controlled by chkconfig. To see the list of services that are enabled, use the command:

$ /sbin/chkconfig --list grep -w on

Basic network services:

network ntpd syslog xinetd sshd

For system housekeeping:

anacron atd crond

If you are using NFS or yp passwords:

rpcidmapd ypbind portmap nfs nfslock autofs

To watch for disk problems:

smartd readahead

The service comprising the InfiniPath driver and SMA:

infinipath

Other services may be required by your batch queuing system or user community.

Disable Powersaving Features

If you are running benchmarks or large numbers of short jobs, it is beneficial to disable the powersaving features of the Opteron. The reason is that these features may be slow to respond to changes in system load.

For rhel4, fc3 and fc4, run this command as root:

# /sbin/chkconfig --level 12345 cpuspeed off
