Building Linux cluster for mechanical engineering software

Hello everybody,

I'm new here in the forum and first i will greet everybody.

Also I'm new with the issue of HPC, but I have to inform my urgently.

My issue:
I'm a mechanical engineer, specialised on simulation like fluid dynamics (CFD) and FEM. Especially I'm programming software for this case.

Everyone who knows CFD, knows already which resources such a simulation needs. In the past I worked on a workstation (Dual-Core Xeon E5), but now I have to build a cluster, especially which can manage the jobs in different queues.

My requirements:
- It should be a linux cluster
- I want to build a cluster with some (for the beginning two) dual-core xeon servers, more machines will follow soon.
- For the special software tools (Ansys CFD) a clone of rhel 6.3 (scientific linux 6.5 is already working) is necesarry.
- For the user GUIs (meshing for CFD or monitor the simulation) a X-Server, which is available by rdp or/and NX, is needed
- For the software I build on my own, I will take experience with GPGPU- and MPI - Programming (not so important, this issue can wait)

I think that are the important values for the Cluster. For that issue I had searched a long time, but I don't found many information about hpc-cluster building and I don't found good literature therefor.

Because of that my questions:
- Are there a good HowTo to build those cluster ?
- Which (special) hardware do I need ?
- Which software do I need for all that (user administration, parallel filesystem, batch system to manage the jobs, cluster-monitoring, MPI, ...) ?
- Can I use only open-source software ?
- Should I use a VM with another linux as base?

I know these are many questions, but I don't find another way and the time is running out.

I'm very happy about every helpful answer. I want to thank you in advance!!

mkqdisk

mkqdisk(8)						      Quorum Disk Management							mkqdisk(8)

NAME

       mkqdisk - Cluster Quorum Disk Utility

WARNING

       Use of this command can cause the cluster to malfunction.

SYNOPSIS

       mkqdisk [-?|-h] | [-L] | [-f label] [-c device  -l label] [-d [-d ...]]

DESCRIPTION

       The mkqdisk command is used to create a new quorum disk or display existing quorum disks accessible from a given cluster node.

OPTIONS

       -c device -l label
	      Initialize  a new cluster quorum disk.  This will destroy all data on the given device.  If a cluster is currently using that device
	      as a quorum disk, the entire cluster will malfunction.  Do not run this on an active cluster  when  qdiskd  is  running.	 Only  one
	      device  on  the  SAN should ever have the given label; using multiple different devices is currently not supported (it is expected a
	      RAID array is used for quorum disk redundancy).  The label can be any textual string up to 127 characters - and is therefore  enough
	      space to hold a UUID created with uuidgen(1).

       -f label
	      Find the cluster quorum disk with the given label and display information about it.

       -L     Display information on all accessible cluster quorum disks.

       -d     Increase debugging level.  Specify multiple times for more information.  Currently, specifying more than twice has no effect.
