ANSYS HPC Packs
Enablers of high fidelity, ANSYS HPC Packs allow scalability in use of high-performance computing to whatever level a simulation requires. A group of ANSYS HPC Packs can be used to enable entry-level parallel processing for multiple simulations or can be combined to offer highly scaled parallel for the most challenging projects.
Whatever the simulation need, ANSYS HPC provides the parallel processing capability required to accelerate time-to-solution and solve the highest fidelity problems. The portfolio of ANSYS mechanical and fluid solvers — including ANSYS Mechanical, ANSYS Autodyn, ANSYS Fluent, ANSYS CFX, ANSYS Icepak, and ANSYS Polyflow software — all use the same ANSYS HPC licenses to execute in parallel. Buy once, deploy once and use parallel processing when and where it is needed. HPC capabilities are available for ANSYS electromagnetics products as well.
ANSYS HPC Packs are a flexible way to license parallel processing capability. For single users who want the ability to run simulations on a workstation, a single ANSYS HPC Pack provides great value with increased throughput of up to 8 times. For users with access to larger HPC resources, multiple HPC Packs can be combined to enable parallel processing on hundreds or even thousands of processing cores. ANSYS HPC Packs offer virtually unlimited parallel processing for the biggest jobs, combined with the ability to run multiple jobs using everyday parallel capacity.
ANSYS HPC Packs enable acceleration using graphical processing units (GPUs) when used in conjunction with ANSYS applications that support GPU computing. ANSYS Mechanical offers GPU acceleration for direct sparse and PCG/JCG iterative solvers in both shared- and distributed-memory modes.
The latest version of ANSYS software extends this to support for multiple GPUs per machine, resulting in an increase in scalable performance versus use of a single GPU. In addition, large models that exceeded the memory capacity of a single GPU (and disallowed its use) fit with multi-GPU memory and benefit from acceleration.
ANSYS Mechanical customers can interchangeably use CPU cores and multiple GPUs — on a workstation or on a GPU-enabled server — to accelerate most simulation workloads.
With ANSYS Fluent, view factors and ray-tracing (radiation) on GPUs are fully supported features, leading to dramatic reduction in computational time for these steps in the simulation. Users can write UDFs to take advantage of GPUs.
