Ansys, Inc. offers the following high performance computing license options:
| Ansys HPC - These physics-neutral licenses can be used to run a single analysis across multiple cores . |
| Ansys HPC Packs - These physics-neutral licenses share the same characteristics of the Ansys HPC licenses but are combined into predefined packs to give you greater value and scalability. |
For detailed information on these HPC license options, see HPC Licensing in the Ansys, Inc. Licensing Guide.
The order in which HPC licenses are used is specified by your user license preferences setting. See Specify Product Order in the Ansys, Inc. License Management Guide for more information on setting user license product order.
You can choose a particular HPC license by using the Preferred Parallel Feature
command line option. The format is ansys242 -ppf
<license feature name>, where <license
feature name> is the name of the HPC license option that you want
to use. This option forces Mechanical APDL to use the specified license feature for the
requested number of parallel cores or GPUs. If the license feature is entered
incorrectly or the license feature is not available, a license failure occurs.
All types of parallel processing (DMP, SMP, and hybrid) allow you to use four CPU cores without using any HPC licenses. Ansys HPC licenses add cores to this base functionality, while the Ansys HPC Pack licenses function independently of the four included cores.
In a similar way, you can use up to four CPU cores and GPUs combined without any HPC licensing (for example, one CPU and three GPUs). The combined number of CPU cores and GPUs used cannot exceed the task limit allowed by your specific license configuration.
