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!!

ccs_config_validate

CCS_CONFIG_VALIDATE(8)					      System Manager's Manual					    CCS_CONFIG_VALIDATE(8)

NAME

       ccs_config_validate

DESCRIPTION

       Usage:

       ccs_config_validate [options]

OPTIONS

       -h     Print this help, then exit

       -V     Print program version information, then exit

       -v     Produce verbose output

   Validating XML configuraton files:
       -f configfile
	      Validate an alternate config file without preloading it with default values.

       -l configfile
	      Validate an alternate config file with preloading of default values (recommended option).

   Advanced options:
       -r     Force validation of runtime config

       -C config_loader Override config plugin loader

       -t tempfile
	      Force temporay file to tempfile

       -n     Do not remove temporary file

       -o     Overwrite temporary file (dangerous)

DEFAULT

       Default operation for ccs_config_validate is to load the currently configured environment and verify the outcoming configuration.

       Example 1: current environment uses a configuration file (/etc/cluster/cluster.conf).
	      The  user  modifies  cluser.conf and executes ccs_config_validate without options.  The tool will validate the modified cluster.conf
	      after including default values.

       Example 2: current environment is set to load the configuration from LDAP. Users
	      modifies LDAP databse and before pushing the change to the nodes, she/he can issue ccs_config_validate to verify the contents o  the
	      LDAP database automatically (as long as the correct LDAP environment is set in the cman/cluster sysconfig/defaults files).
