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!!

DESCRIPTION

       crm_report - Create a tarball containing everything needed when reporting cluster problems

OPTIONS

       -V     increase verbosity

       -v,--version
	      software version

       --features
	      software features

       -f, --from time
	      time to start from: "YYYY-M-D H:M:S"  (do not forget the quotes)

       -t, --to time
	      time to finish at (default: now)

       -T, --cts test
	      CTS test or set of tests to extract

       --cts-log
	      CTS master logfile

       -n, --nodes nodes
	      node names for this cluster only needed if the cluster is not active on the current machine accepts both -n "a b" and -n a -n b

       -l, --logfile file
	      log file to collect, normally this will be determined automatically

       -p patt
	      additional regular expression to match variables to be removed (default: "passw.*")

       -M     collect only the logs specified by -l

       -S, --single-node
	      single node operation; don't try to start report collectors on other nodes

       -c, --cluster type
	      force the cluster type (corosync,openais,heartbeat,logmaster)

       -A, --openais
	      force the cluster type to be OpenAIS

       -C, --corosync
	      force the cluster type to be CoroSync

       -H, --heartbeat
	      force the cluster type to be Heartbeat

       -u, --user user
	      ssh username for cluster nodes (default: root)

       --dest a custom destination directory/file
