How to check performance of your HPC cluster?

Hello Everybody,

I have few queries :

Do you have any idea how to check the performance of HPC cluster having mpich on top of centos 6.2?
Are there any standard programs (like FFT, graphics rendering etc) to check the performance of mpi cluster with single node and multiple nodes?
Can we check the performance of single core and dual core?
Can we benchmark small cluster of 4 nodes or is benchmarking softwares are only for big clusters?

Thanks..

cmhaltcl

cmhaltcl(1m)															      cmhaltcl(1m)

NAME

       cmhaltcl - halt a high availability cluster

SYNOPSIS

       cmhaltcl [-f] [-v]

DESCRIPTION

       cmhaltcl  causes  all  nodes  in a configured cluster to stop their cluster daemons, optionally halting all packages or applications in the
       process.

       To stop a cluster, a user must either be superuser(UID=0), or have an access policy of FULL_ADMIN  allowed  in  the  cluster  configuration
       file. See access policy in cmquerycl(1).

       This  command  will  halt  all  the  daemons on all currently running systems.  If the user only wants to shutdown a subset of daemons, the
       cmhaltnode command should be used instead.

   Options
       cmhaltcl supports the following options:

	      -f   Force the cluster to shutdown even if packages or group members are currently running.  This will cause the packages and  group
		   members to be halted.  If a package halt fails, the cluster halt will also fail.

	      -v   Verbose output will be displayed.

RETURN VALUE

       cmhaltcl returns the following value:

	       0   Successful completion.
	       1   Command failed.

EXAMPLES

       Halt the cluster daemons:

	      cmhaltcl
