Enabling New Server Architectures With The CXL Interconnect


The ever-growing demand for higher performance compute is motivating the exploration of new compute offload architectures for the data center. Artificial intelligence and machine learning (AI/ML) are just one example of the increasingly complex and demanding workloads that are pushing data centers to move away from the classic server computing architecture. These more demanding workloads can be... » read more

How The Doubling Of Interconnect Bandwidth With PCI Express 6.0 Impacts IP Electrical Validation


As a result of the innovations taking place in CPUs, GPUs, accelerators, and switches, the interface in hyperscale datacenters now requires faster data transfers both between compute and memory and onto the network. PCI Express (PCIe®) provides the backbone for these interconnects and is used to build protocols such as Computer Express Link (CXL™) and Universal Chiplet Interconnec... » read more

CXL-Based Memory Pooling System Meets Cloud Performance Goals And Significantly Reduces DRAM Cost


A technical paper titled "Pond: CXL-Based Memory Pooling Systems for Cloud Platforms" was published by researchers at Virginia Tech, Intel, Microsoft Azure, Google, and Stone Co. Abstract "Public cloud providers seek to meet stringent performance requirements and low hardware cost. A key driver of performance and cost is main memory. Memory pooling promises to improve DRAM utilization and t... » read more

Efficiently Process Large RM Datasets In Underlying Memory Pool, Disaggregated Over CXL (KAIST)


A technical paper titled "Failure Tolerant Training with Persistent Memory Disaggregation over CXL" was published (preprint) by researchers at KAIST and Panmnesia. "TRAININGCXL can efficiently process large-scale recommendation datasets in the pool of disaggregated memory while making training fault tolerant with low overhead," states the paper. Find the technical paper here. or here (IEE... » read more

CXL Picks Up Steam In Data Centers


CXL is gaining traction inside large data centers as a way of boosting utilization of different compute elements, such as memories and accelerators, while minimizing the need for additional racks of servers. But the standard is being extended and modified so quickly that it is difficult to keep up with all the changes, each of which needs to be verified and validated across a growing swath of h... » read more

What Does 2023 Have In Store For Chip Design?


Predictions seem to be easier to make during times of stability, but they are no more correct than at any other period. During more turbulent times, fewer people are courageous enough to allow their opinions to be heard. And yet it is often those views that are more well thought through, and even if they turn out not to be true, they often contain some very enlightening ideas. 2022 saw some ... » read more

Adapting To Broad Shifts Essential In 2022


Change creates opportunity, but not every company is able to respond quickly enough to take advantage of those opportunities. Others may respond too quickly, before they properly understand the implications. At the start of a typical year, optimism is in plentiful supply. Any positive trend is seen as continuing, and any negative is seen as turning around. Normally the later in the year that... » read more

Is UCIe Really Universal?


Chiplets are rapidly becoming the means to overcome the slowing of Moore's Law, but whether one interface is capable of joining them all together isn't clear yet. The Universal Chiplet Interconnect Express (UCIe) believes it will work, but some in the industry remain unconvinced. At least part of the problem is that interconnect standards are never truly finished. Even today, the protocols tha... » read more

CXL 3.0: From Expansion To Scaling


At the Flash Memory Summit in August, the CXL Consortium released the latest, and highly anticipated, version 3.0 of the Compute Express Link (CXL) specification. This new version of the specification builds on previous generations and introduces several compelling new features that promise to increase data center performance and scalability, while reducing the total cost of ownership (TCO). ... » read more

How Memory Design Optimizes System Performance


Exponential increases in data and demand for improved performance to process that data has spawned a variety of new approaches to processor design and packaging, but it also is driving big changes on the memory side. While the underlying technology still looks very familiar, the real shift is in the way those memories are connected to processing elements and various components within a syste... » read more
