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..

clinfo

clinfo(1M)						  System Administration Commands						clinfo(1M)

NAME

       clinfo - display cluster information

SYNOPSIS

       clinfo [-nh]

DESCRIPTION

       The clinfo command displays cluster configuration information about the node from which the command is executed.

       Without	arguments, clinfo returns an exit status of 0 if the node is configured and booted as part of a cluster. Otherwise, clinfo returns
       an exit status of 1.

OPTIONS

       The following options are supported:

       -h	Displays the highest node number allowed to be configured. This is different from the maximum number of nodes supported in a given
		cluster. The current highest configured node number can change immediately after the command returns since new nodes can be dynam-
		ically added to a running cluster.

		For example, clinfo -h might return 64, meaning that the highest number you can use to identify a node is 64. See the Sun  Cluster
		3.0 System Administration Guide for a description of utilities you can use to determine the number of nodes in a cluster.

       -n	Prints the number of the node from which clinfo is executed.

EXIT STATUS

       The following exit values are returned:

       0	Successful completion.

       1	An error occurred.

		This is usually because the node is not configured or booted as part of a cluster.
