Speeding Up Applications For Intel-Based Systems

New Compilers Speed Up Applications For Intel-Based Systems

Intel Compilers Pave the Way for Intel's Hyper-Threading Technology

Intel Corporation today introduced updated tools to help software developers optimise applications for Intel’s expanding family of architectures with key innovations such as Intel’s Hyper Threading Technology.

Version 7.0 of Intel® C++ and Intel® Fortran compilers for Windows* and Linux* can improve the performance of applications for Intel® Itanium® 2, Intel® Xeon™ and Intel® Pentium® 4 processor-based systems up to 40 percent when compared to compilers currently available from other vendors.**

Software developers use compilers to translate a programming language, such as C++ or Fortran, into the machine language understood by the processor. A more efficient compiler results in better application performance. Intel’s compilers are designed to help software developers deliver improved performance for their applications running on Intel-based computing and communication systems. “Intel compilers enable software developers to make their applications more competitive with improved performance,” said Peter Kerney, Senior Solution Architect, Intel Australia/New Zealand.

“Intel’s high-performance tools are also compatible with leading development environments for Windows and Linux.”

Because of Intel’s expertise in processor architecture, its compilers have been highly optimised for the Intel Itanium 2, Intel Pentium 4 and the Intel Xeon processors, resulting in a better compiled application for faster operations.

Types of applications that will achieve enhanced performance when built using Intel compilers include commercial, transaction-oriented computing, computationally intensive financial, engineering and scientific applications, digital media, gaming and special effects. The new compilers support many features of Compaq* Visual Fortran, including command line compatibility and include extensive integration into Microsoft* Visual Studio.

The Linux version provides GNU compatibility to C++ with the adoption of the C++ application binary interface. These compatibility features make it easier for application developers to start using Intel compilers to see how their applications might perform better on the Intel Architecture.

Intel’s compilers also help developers produce multi-threaded applications and take advantage of Intel’s Hyper-Threading technology. Threading is a software development technique that identifies tasks that can be done simultaneously.

Intel’s Hyper-Threading technology enables a single physical processor to create a simulated logical processor to run multiple tasks at the same time. The new version 7.0 Intel Compilers include an auto-parallelization option that automatically looks for opportunities in applications to create multiple execution threads and enhancements to OpenMP* support.

OpenMP is the industry standard that enables the use of high-level directives that simplify the creation and management of multi-threaded application software. “Our application is heavily used in very large and time consuming data mining applications, so it is of great importance to get the best performance possible,” said Dr. Fons Rademakers, senior scientist at CERN. “We ported 800,000 lines of C++ and 90,000 lines of C source code to the Intel compiler in one afternoon, an activity that previously took us about a week.”

Version 7.0 of the Intel C++ Compilers for Windows and Linux are now available for the suggested list prices of $US399 each. Version 7.0 of the Intel Fortran Compilers for Windows and Linux are now available for the suggested list prices of $US499 and $US699 respectively. The compilers are available today from Intel and resellers worldwide for download and will be available on CDROMs by the end of the month.
