SAN JOSE, Calif., Oct. 26 — Integrated Device Technology, Inc. (IDT), the Analog and Digital Company delivering essential mixed-signal semiconductor solutions, today announced the introduction of the industry’s first low-power DDR3 memory buffer capable of operating with transfer speeds up to 1866 megatransfers per second (MT/s). The new device affirms IDT’s leadership in memory interface solutions by advancing the top data transfer rates of DDR3 load-reduced dual-inline memory modules (LRDIMMs) and allowing system makers to benefit from increased memory capacity at higher speeds. IDT’s memory buffer is a critical component for advanced memory subsystems in servers, workstations, and storage applications.
The MB3518 is a low-power DDR3 memory buffer capable of operating speeds up to 1866 MT/s with 2 LRDIMMs in a channel. Assuming quad-rank LRDIMMs at 32 GB density, this equates to 512 GB of capacity at 1866 MT/s in a typical server, which can be doubled to over 1 TB using eight-rank 64 GB LRDIMMs, expected to launch in 2013. This represents a fourfold improvement in relative density at the highest speed grades over standard registered dual-inline memory modules (RDIMMs), enabling computing systems to support more memory and improve application performance. The memory buffer can operate at 1.5 V or 1.35 V, offering the industry’s lowest power consumption without sacrificing performance. This translates directly into huge operational cost savings for the end user in power and cooling.
“As the leader of memory interface solutions, IDT is raising the limits of LRDIMM performance,” said Mario Montana, vice president and general manager of the Enterprise Computing Division at IDT. “With a focus on low power and high performance, IDT’s customers can realize the benefit of increased speeds while still developing energy-efficient solutions that will lower datacenter operation costs and reduce carbon footprints. From a system perspective, IDT’s rich portfolio of interface and interconnect products offers a compelling value proposition for a wide range of customers looking to build the most advanced enterprise server and storage equipment on the market.”
“Micron is focused on delivering LRDIMM solutions that drive performance while lowering power to meet the demands of our customers in the high-performance computing (HPC), data center, and cloud computing segments. We are pleased to be working closely with IDT to enable the next generation of LRDIMM products,” said Robert Feurle, vice president DRAM Marketing at Micron Technology, Inc.
IDT memory buffers offer proprietary debug and validation features including per-pin, on-die oscilloscope capability and built-in logic analyzer capture to expedite the development, validation, and test of fully-buffered DIMM topologies. These features are especially important for the memory-buffer-to-DRAM interface on the LRDIMM module, since it is completely isolated from the host controller and automated tester. The IDT memory buffers meet the stringent specifications set forth by the Joint Electronic Device Engineering Council (JEDEC).

During a conversation this week with Cray CEO, Peter Ungaro, we learned that the company has managed to extend its reach into the enterprise HPC market quite dramatically--at least in supercomputing business terms. With steady growth into these markets, however, the focus on hardware versus the software side of certain problems for such users is....

The world's largest supercomputers, like Tianhe-2, are great at traditional, compute-intensive HPC workloads, such as simulating atomic decay or modeling tornados. But data-intensive applications--such as mining big data sets for connections--is a different sort of workload, and runs best on a different sort of computer.

The advent of low-power mobile processors and cloud delivery models is changing the economics of computing. But just as an economy car is good at different things than a full size truck, an HPC workload still has certain computing demands that neither the fastest smartphone nor the most elastic cloud cluster can fulfill.

For all the progress we've made in IT over the last 50 years, there's one area of life that has steadfastly eluded the grasp of computers: understanding human language. Now, researchers at the Texas Advanced Computing Center (TACC) are utilizing a Hadoop cluster on its Longhorn supercomputer to move the state of the art of language processing a little bit further.
