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!!

cmdeleteconf(1m)														  cmdeleteconf(1m)

NAME
cmdeleteconf - Delete either the cluster or the package configuration SYNOPSIS
cmdeleteconf [-f] [-v] [-c cluster_name] [[-p package_name]...] DESCRIPTION
cmdeleteconf deletes either the entire cluster configuration, including all its packages, or only the specified package configuration. If neither cluster_name nor package_name is specified, cmdeleteconf will delete the local cluster's configuration and all its packages. If the local node's cluster configuration is outdated, cmdeleteconf without any argument will only delete the local node's configuration. If only the package_name is specified, the configuration of package_name in the local cluster is deleted. If both cluster_name and pack- age_name are specified, the package must be configured in the cluster_name, and only the package package_name will be deleted. cmdelete- conf with only cluster_name specified will delete the entire cluster configuration on all the nodes in the cluster, regardless of the con- figuration version. The local cluster is the cluster that the node running the cmdeleteconf command belongs to. Only a superuser, whose effective user ID is zero (see id(1) and su(1)), can delete the configuration. To delete the cluster configuration, halt the cluster first. To delete a package configuration you must halt the package first, but you do not need to halt the cluster (it may remain up or be brought down). To delete the package VxVM-CVM-pkg (HP-UX only), you must first delete all packages with STORAGE_GROUP defined. While deleting the cluster, if any of the cluster nodes are powered down, the user can choose to continue deleting the configuration. In this case, the cluster configuration on the down node will remain in place and, therefore, be out of sync with the rest of the cluster. If the powered-down node ever comes up, the user should execute the cmdeleteconf command with no argument on that node to clean up the config- uration before doing any other Serviceguard command. Options cmdeleteconf supports the following options: -f Force the deletion of either the cluster configuration or the package configuration. -v Verbose output will be displayed. -c cluster_name Name of the cluster to delete. The cluster must be halted already, if intending to delete the cluster. -p package_name Name of an existing package to delete from the cluster. The package must be halted already. There should not be any packages in the cluster with STORAGE_GROUP defined before having a package_name of VxVM-CVM-pkg (HP-UX only). RETURN VALUE
Upon completion, cmdeleteconf returns one of the following values: 0 Successful completion. 1 Command failed. EXAMPLES
The high availability environment contains the cluster, clusterA , and a package, pkg1. To delete package pkg1 in clusterA, do the following: cmdeleteconf -f -c clusterA -p pkg1 To delete the cluster clusterA and all its packages, do the following: cmdeleteconf -f -c clusterA AUTHOR
