Scaling Up Engineering Analysis using Windows HPC Server 2008 Todd Wedge Platform Strategy Advisor, HPC Microsoft

High Productivity for HPC HPC for ANSYS Benchmarks & Case Studies Discussion Agenda

Why Clusters? Clusters enable bigger simulations (more accuracy) – Typical FEA models require 4-8 GB RAM Today’s more demanding models might consume 100 GB – Typical CFD models require 2-10 GB RAM Today’s more demanding models might consume GB Clusters deliver turnaround time – Clusters can yield nearly linear scaling A typical simulation might run for 8 hours on a single CPU → Becomes (ideal case) 1 hour on an eight-core cluster Clusters can scale up with demand – More simulations (more design options) Optimization studies might require simulations

Simplified parallel development High Productivity Computing HPC and IT data centers merge, streamlined cluster management Users with broad access to multiple cores and servers

“ Provide the platform, tools and broad ecosystem to reduce the complexity of HPC by making parallelism more accessible to address future computational needs.” Microsoft’s Vision for HPC Ease deployment for larger scale clusters Simplify management for clusters of all scale Integrate with existing infrastructure Address needs of traditional supercomputing Address emerging cross-industry computation trends Enable non-technical users to harness the power of HPC Increase number of parallel applications and codes Offer choice of parallel development tools, languages and libraries Drive larger universe of end-users, developers, and system administrators

Windows HPC Server

Complete, integrated platform for HPC Clustering Built on top Windows Server bit Operating System Addresses the needs of traditional and emerging HPC Windows Server 2008 HPC Edition Secure, Reliable, Tested Support for high performance hardware (x64, high-speed interconnects) Microsoft HPC Pack 2008 Job Scheduler Resource Manager Cluster Management Message Passing Interface Microsoft Windows HPC Server 2008 Integrated Solution out-of-the-box Leverages investment in Windows administration and tools Makes cluster operation easy and secure as a single system Windows HPC Server 2008

High Performance Computing Drivers Bigger Simulations – More geometric detail – More complex physics More Simulations – On time insight – Multiple design options – Automated optimization Memory (lots) Capacity (more) Speed (more) Data Management (lots)

Microsoft – ANSYS Joint Value To increase compute capacity so that engineers, product designers, and performance evaluators can generate high- fidelity simulation results faster and more economically To help IT groups leverage in- house skills, existing technologies, and familiar admin/management interfaces by integrating HPC with their Windows infrastructures

Customer Success: Spraying Systems Co. Deployed Windows HPC with FLUENT complex simulation of industrial spray systems. Achieved shorter run times for simulations which had been tying up engineering workstations Achieved 12X increase in computation speed Sample run time reduced from 192 hours to 16 hours Enabled more detailed, accurate simulations Freed up workstations for setup Leveraged existing Windows infrastructure and expertise “Using a dual or quad core workstation is fine for smaller simulations, but for complex, extensive simulations event multi-core workstations couldn’t complete the computations in a reasonable timeframe.” - Rudolf Schick, Vice President, Spray Analysis & Research Services

Deployed Windows HPC with ANSYS CFX and FLUENT for upstream and downstream applications. Engineers running 5-10 simultaneous simulations using 8-30 core per job. – Improved productivity time for research team – Simpler, more centralized support of clusters “With Windows HPC, setup time has decreased from several hours – or even days for some clusters – to just a few minutes, regardless of cluster size.” IT Manager, Petrobras CENPES Customer Success: Petrobras

Windows HPC Server 2008 Support ANSYS 12.0 supports Windows HPC Server 2008 – ANSYS Mechanical, ANSYS FLUENT, ANSYS CFX, HFSS 12.0 Builds on success with ANSYS R11 and Windows CCS – Full support for job scheduler and MS-MPI – Improved control: Map processes to nodes, sockets, and cores – More performance: Greatly improved parallel scaling based on network direct MPI

Job Scheduler Support – ANSYS Workbench Allocates the necessary resources to the simulations Tracks the processors associated with the job Deallocates the resources when the simulation finishes

Performance Gain – ANSYS Mechanical ANSYS R11 on WCCS vs. ANSYS R12 on Windows HPC Server 2008

ANSYS FLUENT Public Benchmarks Conclusions: For ANSYS FLUENT 12.0, Windows HPC Server 2008 is delivering the same or faster performance than Linux on the same hardware (HP BL2x220 3GHz with 16GB memory per node and InfiniBand interconnect). Reference: Dataset is External Flow over a Truck Body, 14M cells, public benchmark. ANSYS FLUENT 12.0 data posted at Windows HPC data run with pre-release ANSYS FLUENT Results run by HP and submitted/approved by ANSYS.
