IBM and Intel Corporation have developed a proposal to enhance PCI Express technology to address the performance requirements of new usage models, such as visualisation and Extensible Markup Language (XML). The proposal, codenamed 'Geneseo,' outlines enhancements that aims to enable faster connectivity between the processor and application accelerators, improving the range of design options for hardware developers.

Applications that will benefit include visualisation, such as complex weather modelling; math and physics, such as data intensive financial applications; and content processing, such as the encryption and decryption of communications infrastructure data.

“IBM is co-founding a new open standard for attaching accelerators and co-processors to server platforms,” said Dr. Tom Bradicich, IBM fellow and chief technology officer, System x and BladeCenter Servers. “Like PCI-X, InfiniBand and PCI Express, this new architecture defines a standards-based approach for general purpose server accessibility within new and emerging application areas, such as encryption, visualisation, XML and complex mathematical modelling.”

“Five years ago Intel, along with IBM and other industry leaders, laid out a ten-year vision for an open, standards-based interface for the entire computer industry,” said Pat Gelsinger, senior vice president, general manager, Intel’s Digital Enterprise Group. “In 2004, PCI Express was the first step and today is the choice for desktop, mobile and server systems. Geneseo is the next step in this vision and aims to address new requirements and opportunities that come with platforms.”

Technology companies including Adaptec, AGEIA Technologies, Altera Corporation, Broadcom Corporation, Celoxica, Cisco Systems, ClearSpeed Technology, Dell, EMC Corporation, Emulex Corporation, HP, INTEGRATED DEVICE TECHNOLOGY, LECROY CORPORATION, Linux Networx, LSI Logic, Mellanox Technologies, Myricom, NetEffect, Novell, NVIDIA, PLX Technology, PMC-Sierra, QLogic, Sun Microsystems, Synopsys, Tektronix, Xambala Inc., Xilinx and Xtreme Data support Geneseo.

PCI Express technology was first delivered in client and server computing platforms in 2004. Its introduction signaled the transition of computing platform I/O from the parallel bus model that had existed since the PC industry’s inception to a high-speed, serial I/O standard.
