Fluent Inc., the world leader in computational fluid dynamics (CFD) software and services, today announces that the recently released beta version of its flagship flow simulation software, FLUENT 6.3, includes significant performance improvements on the Linux operating system (OS), stemming from the adoption of Intel® C++ Compiler 9.0 for Linux. Using the Intel C++ Compiler, FLUENT 6.3 beta has been compared to nine typical CFD examples and shows performance improvements ranging from a few percent up to as much as 50%. The compiler has been applied mainly to the Intel® Xeon® processor, but, it is also showing significant performance gains with the Intel® Itanium® processor. FLUENT is the most popular CFD software in the world by far, and is used extensively on Linux OS.

"Fluent has moved to the Intel Compiler for our upcoming release because it provided the best performance and robustness of the many compilers that we tested,' notes Paul Bemis, VP Marketing at Fluent. "Many of our customers are using Linux-based systems and this FLUENT 6.3 performance gain will help reduce the turnaround time on CFD computations. Intel has worked closely with us in order to tune and improve our software's performance and we are very happy with the outcome of the collaboration."

"Intel understands that software development products are a critical part of the overall ecosystem required for high-performance computing," notes James Reinders, director of marketing and business for the Intel Software Products Division. "Fluent chose Intel C++ Compiler for Linux to help customers achieve optimal performance for supercomputing applications such as simulations, visualization and scientific analysis."
