ANSYS Software Offers 64-Bit Support for Microsoft Windows Compute Cluster Server 2003

Solution Improves Engineering Simulation Speed and Accuracy

SOUTHPOINTE, Pa., Sept. 19 /PRNewswire-FirstCall/ -- ANSYS, Inc. (Nasdaq: ANSS), a global innovator of simulation software and technologies designed to optimize product development processes, today announced that the upcoming releases of its multiphysics simulation software - ANSYS(R) 11.0 and FLUENT(R) 6.3 - will include support for Microsoft Windows Compute Cluster Server 2003. Enabling high-performance computing (HPC) on the Microsoft Windows platform, the new solution helps customers deploy computer-aided engineering (CAE) at a higher level than in the past, decreasing the time required for simulations and increasing the accuracy of results.

ANSYS 11.0 and FLUENT 6.3 take advantage of the Microsoft Message Passing Interface (MPI) software layer in Windows Compute Cluster Server 2003 for data communication between processors on the cluster. The new releases also use the Microsoft Job Scheduler in Windows Compute Cluster Server 2003, providing an off-the-shelf solution for launching and controlling jobs on the cluster.

"Windows Compute Cluster Server 2003 represents a breakthrough in bringing high-performance computing into the mainstream of CAE," said Ferit Boysan, vice president and general manager at ANSYS, Inc. "Many customers are already using Microsoft Windows, and an easily deployed cluster solution that integrates with their current environment and skill-set allows them to increase the value they derive from simulation. We see great scaling on clusters using Windows Compute Cluster Server 2003, so customers can dramatically reduce the time spent waiting for engineering insight."

Using Windows Compute Cluster Server 2003 on an HP ProLiant cluster, ANSYS, Inc. recently solved a 100 million-degree-of-freedom structural analysis problem to validate its commercial robustness. "Before 64-bit- enabled Windows Compute Cluster Server 2003, our customers would need a shared memory machine or Linux cluster to solve 100 million-degree-of-freedom models and beyond. It's very exciting to deliver this type of performance with Microsoft Job Scheduler integrated with ANSYS(R) Workbench(TM) to our customers," said Mike Wheeler, vice president and general manager at ANSYS, Inc.

"We believe cost and complexity shouldn't be barriers to innovation and discovery," said Kyril Faenov, director of high-performance computing at Microsoft Corp. "We are pleased to be working with ANSYS to offer HPC solutions that are easier to deploy, operate and integrate with existing infrastructure and tools."
