MAXIMUM PERFORMANCE AND COMPATIBILITY

The QLogic PathScale™ Compiler Suite represents the highest-perform-ance 64-bit C, C++ and Fortran compilers for Linux-based environments. This advanced compiler suite takes advantage of the unique high-per-formance 64-bit features of both the Advanced Micro Devices AMD64 and the Intel® Xeon™ EM64T architectures.

The PathScale compiler includes a world-class“Every Known Optimization”framework purpose built for inserting new optimization techniques to improve performance. At PathScale, poor compiler optimization is considered a bug and a challenge to our development team.


DERIVED FROM PROVEN FOUNDATIONS

Noted for its mature FORTRAN and excellent Optimizer, the PathScale compiler suite is derived from the SGI® /Cray® compiler. PathScale mod-ernized this compiler with OpenMP 2.5 and a gnu C/C++ front-end, and enhanced the code generator to support AMD64 and Intel EM64T proces-sors. The result across all languages, is the world's highest performance 64-bit Linux compiler with complete GNU tool chain compatibility.

In real-world application testing, HPC end-users have experienced up to 40% performance gain over alternative compiler products. This makes the QLogic PathScale Compiler Suite the clear choice for 64-bit computing clusters focused on maximum performance.

OPTIMIZED FOR AMD OPTERON AND INTEL EM64T SYSTEM

The QLogic PathScale Compiler Suite maximizes the performance of appli-cation code when compiled for AMD Opteron systems. With AMD Opteron advantages like complex addressing modes, large register sets, more effi-cient parameter passing and SSE2/3DNow!™ support, 64-bit code will simply perform better on this processor. In addition, inline AMD64 assembly code can be issued.


FLEXIBLE PURCHASING OPTIONS

The Qlogic PathScale Compiler Suite is sold as a subscription service, which includes all major and minor product enhancements, bug fixes, performance improvements, and access to customer support. The subscription is sold on a per developer basis. Perpetual license options are also available.


WORLD CLASS SUPPORT

QLogic provides advanced technical support by some of the best compiler engineering talent in the industry. QLogic treats performance problems as bugs, and provides excellent assistance in application porting and tuning.
