Distributed Analysis
Distributed analysis allows users to split certain types of analyses and solve each portion of an analysis simultaneously on multiple machines. Simulation times can be greatly decreased by using this feature.
- Distributing rows of a parametric table, either as a regular DSO or as Large Scale DSO performed through command line.
- Distributing array solves.
- Distributing domain solves.
- Distributing single or discrete interpolating sweeps.
Communication between machines in remote analysis and distributed analysis can drastically affect performance. Use of a high-speed network system, like Gigabit or Infiniband, is recommended for optimal performance.
All types of distribution use MPI, except when only distributing rows of a parametric table, either as a regular DSO or as Large Scale DSO performed through command line. MPI may also be used if Auto mode is specified, and rows of a parametric table are distributed. MPI must be correctly configured if the distributed analysis uses MPI. See Setting HPC and Analysis Options for setting MPI Licensing and the Ansys Electronics Desktop Installation Guide for details on installing MPI.
Beta Feature: Parallel Component Mesh Adapt for 3D Component Array
If you enable the Beta Feature for Parallel Component Mesh Adapt, you can have parallel mesh adaption for 3D Component arrays. This feature works only with Use Automatic Settings enabled on the active Analysis Configuration.
When running a suitable design with this feature enabled, the Solution Profile will show multiple frequencies being adapted at the same time.
Configure a Distributed Analysis
To configure a distributed analysis, you must select a distributed machine configuration containing a list of machines to use for a simulation, based on memory and CPU considerations (See: Selecting an Optimal Configuration for Distributed Analysis). To create an new distributed machine configuration or to edit an existing one, see Editing Distributed Machine Configurations.
Before you can select a configuration, it must be active. See: Setting HPC and Analysis Options.
To select an existing, active configuration:
- From the Simulation tab, use the Active drop-down menu to select a configuration.
