Ask about rhel cluster with many cores.

Hi everyone!
I plan to build a cluster. Anyone help me some problem:
1. How many node can rhel support in a cluster system?
2. How many processor or core can rhel support in single node?
3. How many processor or core in a node and system give the maximum benefit.
Sorry if my question is silly.
Thank in advance

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.
