Compute Resource Reference

Compute resources define connections to local or remote computing resources including clusters. By default, a Direct compute resource named Default Direct is defined. The following new compute resources can be added to the Design Manager Project by right-clicking the Tools > Compute Resources node and select New Resource:

Direct

Runs the design study using direct execution, such as a local machine or workstation. This option has the following property:

Command Line Options

Specifies additional simulation command line options to pass to the design simulations—such as License Options or other Simcenter STAR-CCM+ options, see Command-Line Reference.

This property is useful for general simulation command line options that you want to save within your Design Manager project.

Examples:

Power Session licensing: -power
Parallel I/O and Power Licensing: -pio -power
Intel MPI: -mpi intel
Power Session licensing and Intel MPI: -power -mpi intel

Alternatively, you can pass simulation options from the command line, see Design Manager Options, which is useful for machine-specific or user-specific options.

As Design Manager controls the resource management for the design simulations, you must not pass resource management options to the design simulations. Therefore, the following resource specification options are not supported:

-batchsystem
-bs
-hostregexpr
-machinefile
-np
-on

Linux Cluster

Runs the design study on a Linux cluster using a generic scheduler.

This option activates the Linux Cluster child node, where you specify the following properties:

Command Line Options: Same as the property of a Direct source.
Job Submit Command: Command that is used to submit each design simulation on the cluster.; The default value qsub -l nodes=1:ppn=8 is set up for a cluster running OpenPBS where each design simulation is submitted on one node running eight cores per node.; To avoid underloading or overloading of compute resources, set Compute Processes to 1. This value disables the Compute Processes property.
Name Identifier: Specifies the flag for the name identifier of a design simulation being submitted to the queue.; The default value -N is set up for a cluster running OpenPBS.
Prefix: Specifies the value for the name identifier that is passed on to the job scheduler. The default value is dm_study_design.
Script File: Allows you to use a submission script that contains the Simcenter STAR-CCM+ execution command and common command line options.; You specify the absolute path and the full name of the script file, which must be available on the cluster drive.; Make sure that the script file has execute permission.

Windows HPC Cluster

Runs the design study on a Windows HPC cluster using the HPC Job Scheduler.

This option activates the Windows HPC Cluster child node, where you specify the following properties:

Command Line Options: Same as the property of a Direct source.
Job Submit Command: Command that is used to submit each design simulation on the cluster.; The default value job submit /numcores:8 is set up for a cluster running the HPC Job Scheduler, where each design simulation is submitted on eight cores. The scheduler allocates the requested cores from the available nodes.; To avoid underloading or overloading of compute resources, set Compute Processes to 1. This value disables the Compute Processes property.
Name Identifier: Specifies the flag for the name identifier of a design simulation being submitted to the queue.; The default value /jobname is set up for a cluster running the HPC Job Scheduler.
Prefix: Specifies the value for the name identifier that is passed on to the job scheduler. The default value is dm_study_design.
Script File: Allows you to use a submission script that contains the Simcenter STAR-CCM+ execution command and common command line options.; You specify the full UNC path and the full name of the script file, which must be available on the cluster drive.; Make sure that the script file has execute permission.
