Semtech Corporation, a high-performance semiconductor, IoT systems and Cloud connectivity service provider, announced the successful demonstration of a 200G per lane (200G/lane) optical transmission link enabled by Semtech's latest FiberEdge 200G PAM4 PMDs and Broadcom's latest generation DSP PHY.
In collaboration with Keysight Technologies Inc., Semtech and Broadcom will be conducting a live demonstration based on Semtech's state-of-the-art FiberEdge 200G PAM4 EML Driver and TIA and Broadcom's leading-edge 5nm 112GBd PAM4 DSP platform in Semtech's booth #1901 and Broadcom's booth #6425 at the Optical Fiber Communication (OFC) 2023 exhibition in San Diego, California from March 7 to 9.
Hot Chips
Scientific Computing World, February 27th, 2023
The server and HPC processor market has been in a period of change. Repeated delays from Intel and strong positioning from AMD have led to a shift from the long-established dominance that Intel has had in this market.
However, the latest news on Intel's upcoming Intel Xeon scalable processors (code-named Sapphire Rapids) suggests that this increased competition is good for scientists and researchers looking for the best price/performance from their hardware investment.
Researchers using HPC now have a wider choice of viable high-performance computing (HPC) hardware to use in their next generation of supercomputers. In November 2022, AMD announced its latest processor in the Epyc Server lineup of CPU chips. As with other Epyc chips, this is primarily designed for cloud providers, enterprises, and organisations using HPC.
Ayar Labs, founded in 2015, is pursuing optics as a means of driving higher interconnect speeds and efficiencies in computing. Now, the company is announcing that it plans to demonstrate a staggering 4Tbps optical solution at the Optical Fiber Communication Conference (OFC) i
In an interview with HPCwire, Ayar Labs CEO Charlie Wuischpard called the solution 'the full realization of 'Ayar Labs'' commercial-grade product' and discussed the future of the company and its products.
But first, some technical details. The optical solution that Ayar Labs will be demoing consists of two key components: a SuperNova laser light source and a TeraPHY optical I/O chiplet. According to Ayar Labs, each SuperNova powers eight fiber links, each of which, in turn, is capable of 256Gbps. That gets you 2.048Tbps in each direction, or 4.096Tbps bidirectional.
AMD CEO sheds some light on what the company plans to do reduce data transfer energy
AMD wants to reduce the cost of communication and is on a crusade to bring down the cost of transferring bits between memory and compute significantly by putting RAM on top of the CPU/GPU.
Company CEO Dr. Lisa Su recently delivered a high level presentation at the International Solid-State Circuits Conference (ISSCC) 2023, speaking extensively about the need to cut down on the amount of energy (expressed in Joules) per computation operations (FLOPS).
