Microsoft Windows HPC Server 2008 Cluster Configuration
Thanks to sponsorship provided by the Microsoft DPE team, Caedium can perform RANS Flow CFD simulations in parallel on a cluster running Microsoft Windows HPC Server 2008. When configured correctly a parallel simulation running on a cluster will perform significantly faster (potentially many times faster) than the equivalent simulation performed in serial (i.e., non-parallel). Here we describe how to configure Caedium to perform parallel simulations on a cluster running Windows HPC Server 2008.
- You have access to a cluster running Microsoft Windows HPC Server 2008.
- You have saved your user ID and password with the Microsoft HPC Cluster Manager. If not then:
- Launch the HPC Pack Cluster Manager
- Select Node Management
- In the Nodes list select the HeadNode Template
- In the Node Actions click Run Command...
- In the Run a Command dialog enter dir in the Command line text entry
- Click Run
- Enter your user ID and password, check the option Remember my password and click OK
- You have downloaded, installed and activated Caedium RANS Flow or Caedium Professional on the head-node of the cluster, e.g., CRAY01. Note do not install Microsoft MPI - it should already be available on the cluster.
- You are familiar with Caedium essentials.
You only need to set the following Caedium preferences once - they will persist across all subsequent Caedium simulations.
- Set up the Caedium temporary directory by creating a new directory on the node where Caedium is installed, e.g., C:\caediumtemp and share the directory, e.g., as \\CRAY01\caediumtemp
- The OpenFOAM distribution (executables and libraries) must be available to all nodes in the cluster, so on the node where Caedium is installed share the default OpenFOAM location, e.g., share C:\Program Files\Caedium\openflow as \\CRAY01\openflow
- In Caedium select the File Toolbar and click the Preferences button . In the Properties Panel set the Application->Temp Directory preference to the shared Caedium temporary directory, e.g., \\CRAY01\caediumtemp
- Set the Physics->OpenFOAM preference to the shared OpenFOAM directory, e.g., \\CRAY01\openflow
- Set the Physics->OpenFOAM->Parallel preference to Cluster, then expand the preference and set Processes to the maximum number of processes available to Caedium to perform parallel simulations, e.g., 50
