Some of your questions are so vague that it is hard to make any informed suggestions. How would you respond if you got a request from someone to tell them how to choose the best vehicle? (Who is going to be driving it? How many passengers do you need to carry? How much weight do you need to be able to tow? How much secured cargo space do you need? What are the weather conditions where it will be driven? What type of terrain does it need to traverse? ...)

I know very little about about ME and nothing about Ansys CFD. Are you trying to build a cluster to support hundreds of users submitting thousands of jobs? Are you trying to build a cluster than can break a single huge job into thousands of threads and run all of those threads simultaneously? Do you have any experience writing thread-safe code?

Can you use only open-source software? Of course you can! You can write all of the code you need and make it available for everyone to use as they see fit.

Does open-source software already exist for all of the code you want to run? How can we guess at that from what you've told us? We have no idea what all of the code you want to run needs to do.

If you don't know the difference between a heterogeneous cluster and a homogeneous cluster, you probably don't have the background needed to design the cluster you want. Please consider hiring an architect with experience setting up and running an HPC data center who you can sit down with and discuss budget, capabilities, computing projects to be run, users to be supported, software to be run, software to be written, etc., etc., etc. Setting up an HPC data center is a very complex, expensive undertaking.

scsetup

scsetup(1M)						  System Administration Commands					       scsetup(1M)

NAME

       scsetup - interactive cluster configuration tool

SYNOPSIS

       scsetup [-f logfile]

DESCRIPTION

       Note -

	 Beginning  with  the Sun Cluster 3.2 release, Sun Cluster software includes an object-oriented command set. Although Sun Cluster software
	 still supports the original command set, Sun Cluster procedural documentation uses only the object-oriented command set. For more  infor-
	 mation about the object-oriented command set, see the Intro(1CL) man page.

       The  scsetup  command  provides the following configuration capabilities, depending on what state the cluster is in when you issue the com-
       mand:

	   o	  When you run the scsetup command at post-installation time, the command performs initial setup tasks, such as configuring quorum
		  devices  and resetting the installmode property. If you did not use automatic quorum configuration when you created the cluster,
		  run the scsetup command immediately after the cluster is installed. Ensure that all nodes have joined the cluster before you run
		  the scsetup command and reset the installmode property.

		  If  you used automatic quorum configuration when you created the cluster, you do not need to run the scsetup command after clus-
		  ter installation. The automatic quorum configuration feature also resets the installmode property of the cluster.

	   o	  When you run the command during normal cluster operation, the scsetup command provides a menu-driven utility. You can  use  this
		  utility to perform most ongoing cluster-administration tasks.

	   o	  When you issue the command from a node that is in noncluster mode, the scsetup utility provides a menu-driven utility for chang-
		  ing and displaying the private IP address range. You must reboot all nodes into noncluster mode before you start  this  form	of
		  the scsetup utility.

       You can issue the scsetup command from any node in the cluster.

       You can use this command only in the global zone.

OPTIONS

       The following options are supported:

       -f logfile	   Specifies  the  name  of a log file to which commands can be logged. If you specify this option, most command sets that
			   the scsetup utility generates are run and logged, or only logged, depending on user responses.
