New at R18.0

- Built-in HPC for New CFD Products

• Premium and Enterprise (solver) license has 4 built-in HPC tasks enabling to run up to 4 parallel cores without requiring additional HPC licenses

• Note:

– In order to go beyond 4 parallel cores for a single simulation, these built-in HPC tasks can be combined with HPC tasks enabled by either ANSYS HPC licenses or an ANSYS HPC Workgroup license

– AIM uses 2 cores and does not use additional HPC

Option 1 – ANSYS HPC

• Basic option for low-level HPC (e.g. 3-4 cores)

• Each core in a parallel run consumes 1x HPC task

• Mechanical licences include 2x free cores

• Becomes expensive if used for large number of cores – hence other options are available!

Key Benefits• Ability to automatically and simultaneously

execute design points while consuming just one set of application licenses

• Scalable because number of simultaneous design points enabled increases quickly with added packs

• Amplifies complete workflow because design points can include execution of multiple applications (pre, meshing, solve, HPC, post)

ANSYS HPC and ANSYS HPC Workgroup give full, flexible use of a pool of licenses.

ANSYS HPC Pack gives “quick” scale-up but is more restrictive in how users can use it.

The ability to be more flexible is why the HPC Workgroup options cost more than the HPC Packs.

Which Type of Licensing is Right For Me?

19 © 2016 ANSYS, Inc. March 12, 2017

ANSYS HPC Pack

- Scalable Pricing for Capability Computing

Example:Running on 2,000 cores instead of 20 cores

at 1.5X cost premium – and not 100X

20 © 2016 ANSYS, Inc. March 12, 2017

ANSYS HPC Workgroup

- Volume Pricing for Capacity Computing

Example:Filling up a 1024- instead of 128-core cluster

with 32-core jobs will cut the price per job in half!

21 © 2016 ANSYS, Inc. March 12, 2017

ANSYS HPC Parametric Pack

- Capacity Computing For Design Exploration

Example:Enabling 64 instead of 4 simultaneous design points

at ~3X cost premium – and not 16X

22 © 2016 ANSYS, Inc. March 12, 2017

Multiple Licensing options to fit different requirements.

HPC Packs for quick scale-up

HPC Workgroup for Flexibility.

GPU’s treated the same as cores in terms of licensing.

As you scale-up License cost decreases per core.

Per core pricing becomes less of an issue.
