TIPS FOR WORKSTATION PERFORM ANSYS 12.1 AND 13.0

CPU MEMORY I/1. Fast processor

2. More Cores for Parallel

execution

3. Large CPU Cache

4. Performance BIOSsettings. Disable HT

1. RAM size is critical

Application data must reside in core

Memory buffered I/O

2. Fill all memory channels

TIPS FOR WORKSTATION PERFORM ANSYS 12.1 AND 13.0

OPERATING SYSTEM PROFESSIONAL GRA1. Genuine Windows® 7 Professional 64-bit 1

2. High performance power plan

1. AMD FirePro and NVIDIA Q

2. Certified OpenGL graphics

3. GPU is used to accelerate

of an ANSYS 13.0 SMP sim

mainly the equation solvers –

Footnotes:1. Systems may require upgraded and/or separately purchased hardware and/or a DVD

drive to install the Windows 7 software and take full advantage of Windows 7functionality. See http://www.microsoft.com/windows/windows-7/ for details.

2. Review the ANSYS Mechanical APDL Performance Guide

3. Review the ANSYS Advanced Analysis Techniques Guide Ch. 16 for GPU AcceleratorCapability

ANSYS BENCHMARKSITERATIVE LANCZOS-BASED DIRECT (SPARv13cg-1 Gas-Struct

• Transient, linear, thermal analysis with 8 load steps

• Iterative JCG Solver, symmetric matrix, 1.1M DOFs,

• Small sized job, good test of memory bandwidth

• GPU accelerator capable

v13cg-2 Engine Block

• Static, linear, structural analysis with 1 load step

• Iterative PCG Solver, symmetric matrix, 6.2M DOFs

• Medium sized job, needs 8GB of memory or more to run well,

good test of memory bandwidth

v13cg-3 Wing Model

• Static, linear, structural analysis with 1 load step

• Iterative PCG Solver, symmetric matrix, 10.7M DOFs

• Large sized job, only needs 4GB of memory to run well due

to MSAVE usage, good test of processor flop speed and

memory bandwidth
