Integrated Device Technology, Inc. ( IDT ®) (NASDAQ: IDTI), the Analog and Digital Company™ delivering essential mixed-signal semiconductor solutions, today announced that the IDT CPS-1848 and CPS-1616 Gen 2 Serial RapidIO ® switches provide the key system interconnect for the low-power BrownDwarf Supercomputer developed by nCore HPC and Prodrive. IDT's RapidIO switches offer 20 Gbps throughput per port with the lowest latency and the highest performance-per-watt compared to other interconnects, enabling nCore and Prodrive to use Texas Instruments’ (TI) RapidIO-equipped processors and leapfrog supercomputing incumbents.
The BrownDwarf supercomputer leverages TI's Keystone-II, which integrates multiple ARM ® Cortex™-A15 MPCore™ processors, and TMS320C66x digital signal processors (DSPs) that feature embedded RapidIO Gen2 endpoints developed by IDT. BrownDwarf's three-shelf ATCA-based system delivers 70 teraflops of performance with 144 AMC-based nodes and 4032 processing cores. Taking into account the entire system power consumption, including processing, interconnect, and infrastructure, this equates to a very impressive 6.4 gigaflops per watt. In addition, the supercomputer is designed to easily scale using open standard RapidIO-based inter-cabinet switching, creating large multi-cabinet systems with up to 64K computing nodes.
nCore HPC and Prodrive selected IDT’s RapidIO switches for key benefits in throughput, latency, reliability and overall system power utilization that could not be achieved with Infiniband- or Ethernet-based approaches. IDT's RapidIO switches offer 20 Gbps of bandwidth per port, 100 ns cut through latency, 300 mW per 10 Gbps of data, up to 240 Gbps of non-blocking switch performance, and built-in reliable transmission. These performance, power, and reliability advantages are essential for supercomputer applications that leverage the power-efficient BrownDwarf platform.
“Our goal was to bring to market the most energy-efficient supercomputer,” said Ian Lintault, Managing Director of nCore. “We leveraged IDT’s RapidIO Gen 2 switches and TI’s RapidIO-equipped Keystone-II devices to create the highest-performance, lowest-power, non-NIC-based network fabric – an achievement that would not have been possible with InfiniBand ® or Ethernet systems used by traditional supercomputing vendors. The BrownDwarf is expected to be in the top tier of the Green 500 world’s most energy-efficient supercomputers.”“We have successfully deployed IDT’s RapidIO Gen2 switches for many customers across various embedded markets,” said Pieter Janssen, CEO at Prodrive. “Our past successes allowed us to quickly leverage the ATCA-based infrastructure for the BrownDwarf platform, going from concept to product launch in fewer than 6 months. RapidIO Gen2 is a key element of our computing solutions strategy and provides a graceful path to upgrade with RapidIO 10xN at 40 Gbps per port.”
