The New CXL Standard


Gary Ruggles, senior staff product marketing manager at Synopsys, digs into the new Compute Express Link standard, why it’s important for high bandwidth in AI/ML applications, where it came from, and how to apply it in current and future designs. » read more

HBM2E: The E Stands for Evolutionary


Samsung introduced the first memory products in March that conform to JEDEC’s HBM2E specification, but so far nothing has come to market—a reflection of just how difficult it is to manufacture this memory in volume. Samsung’s new HBM2E (sold under the Flashbolt brand name, versus the older Aquabolt and Flarebolt brands), offers 33% better performance over HBM2 thanks to doubling the de... » read more

Open Source Processors: Fact Or Fiction?


Open source processors are rapidly gaining mindshare, fueled in part by early successes of RISC-V, but that interest frequently is accompanied by misinformation based on wishful thinking and a lack of understanding about what exactly open source entails. Nearly every recent conference has some mention of RISC-V in particular, and open source processors in general, whether that includes keyno... » read more

System Bits: June 25


Supercomputers around the world At last week’s International Supercomputing Conference in Frankfurt, Germany, the 53rd biannual list of the Top500 of the most powerful computing systems in the world was released. Broken out by countries of installation, China has 219 of the world’s 500 fastest supercomputers, compared with 116 in the United States. Ranking by percent of list flops, the ... » read more

System Bits: May 14


Faster U.S. supercomputers on the way The U.S. Department of Energy awarded a contract for more than $600 million to Cray for an exascale supercomputer to be installed at the Oak Ridge National Laboratory during 2021. Cray will provide its Shasta architecture and Slingshot interconnect for what is dubbed the Frontier supercomputer. Advanced Micro Devices will have a key role in building the... » read more

System Bits: April 8


Computers trained to design materials Researchers in the University of Missouri’s College of Engineering are applying deep learning technology to educate high-performance computers in the field of materials science, with the goal of having those computers design billions of potential materials. “You can train a computer to do what it would take many years for people to otherwise do,” ... » read more

The Building Blocks Of Future Compute


Eric Hennenhoefer, vice president of research at Arm, sat down with Semiconductor Engineering to talk about privacy, security, high-performance computing, accelerators, and Arm’s research. What follows are excerpts of that conversation. SE: Privacy, cybersecurity, silicon photonics, quantum computing are all hot topics today. What do you find really interesting with these emerging areas? ... » read more

PCIe In High-Performance FPGAs


In today's world, when the entire computing industry is talking about high-performance and high-speed applications using FPGAs, what are the factors that can assure such performance and speed? The value and success of today’s high performance computing applications in the areas of DNA Sequencing, High Frequency Trading (HFT) and Encryption/Decryption are predicated upon how fast data can be t... » read more

Fabs Meet Machine Learning


Aki Fujimura, chief executive of D2S, sat down with Semiconductor Engineering to discuss Moore’s Law and photomask technology. Fujimura also explained how artificial intelligence and machine learning are impacting the IC industry. What follows are excerpts of that conversation. SE: For some time, you’ve said we need more compute power. So we need faster chips at advanced nodes, but cost... » read more

Bugs With Long Tails Can Be Costly Pests


I don’t think Van Gogh was considering high performance computing or server architecture, but he made a lot of sense when he said "great things are done by a series of small things brought together." A series of very small things can, and do, create big things: that’s the fundamental premise of long-tail marketing: Amazon, for one has built a strong business from selling millions of niche i... » read more
