The HyperTransport™ Technology Consortium, a non-profit industry organization that manages and promotes low latency HyperTransport technology, today announced a white paper entitled “The Future of High-Performance Computing: Direct Low-Latency Peripheral-to-CPU Connections.”

The white paper focuses on HTX – a new expansion interconnect that brings ultra-low latency and high performance to the input/output (I/O) slot, enabling direct communication with high-performance processors. The HTX expansion connector specification leverages industry-standard HyperTransport technology. It gives system and subsystem manufacturers a standard way to direct connect HyperTransport-enabled high-performance peripherals to HyperTransport-enabled processors, like AMD’s OpteronTM. The high-bandwidth, low-latency HyperTransport link is an integral part of many 64-bit motherboards and a key interprocessor link for multiprocessing systems. The paper addresses some of the challenges related to developing low-cost, high-performance computing solutions and introduces the business and technical advantages of HTX connectivity.

“This white paper illustrates the ability of HTX to deliver leading-edge performance at affordable prices using industry standard, off-the-shelf components,” said Mario Cavalli, general manager of the HyperTransport Consortium. “HTX connectivity is ideal for high-performance peripheral subsystem applications that demand the lowest possible latency such as server clustering, transactional systems and scientific modeling.

According to the paper, HTX provides system and peripheral card manufacturers numerous business benefits such as:

  •     State-of-the-art performance potential
  •     Extremely cost effective
  •     Easy integration
  •     Market and platform universality
  •     Increased market share
  •     Accelerated technology adoption
  •     No need for dedicated systems designs
  •     Multi-core, multi-processor support
  •     High-performance, low cost clusters
  •     Product leadership
  •     Complements general-purpose interconnects

About HyperTransport Technology

HyperTransport is the industry's lowest latency, highest-performance, fully scalable, packet-based interconnect technology serving a wide range of industry segments. It is based on two 2-line to 32-line, asymmetric Low Voltage Differential Signaling (LVDS) links delivering up to 22.4 Gigabytes/second of aggregate CPU to CPU, CPU to I/O bandwidth in a highly efficient point-to-point, daisy-chain topology that replaces complex multi-level, multi-line buses. By enabling system designers to link peripheral subsystems or processors directly to the CPU or to multiple symmetric CPUs, the HyperTransport HTX™ connector makes compute intensive, leading edge CPU-to-I/O and board-to-board designs a reality for server clustering and high performance peripheral applications. HyperTransport technology is embedded in multiple CPU families from AMD, Broadcom, IBM, PMC-Sierra, Raza Microelectronics and Transmeta and in a variety of semiconductors and IP cores. It is fully software-compatible with legacy Peripheral Component Interconnect (PCI), PCI-X and PCI Express technologies.

HyperTransport technology has been deployed in tens of millions of devices used in market leading products such as the Microsoft Xbox, Cisco routers, Apple, HP & Sun workstations, Apple, IBM, HP & Sun servers, HP blade PCs, HP & Sharp notebooks, Cray & IBM supercomputers, and all PCs, servers & cluster workstations based on the AMD Athlon™ 64, the AMD Opteron™ and Transmeta Efficeon processors. 2004 industry estimates from market analyst firm InStat project HyperTransport-based system product shipments to have reached nearly 26 million units in 2004 and to exceed 60 million units in 2006.
