Flipping Processor Design On Its Head


AI is changing processor design in fundamental ways, combining customized processing elements for specific AI workloads with more traditional processors for other tasks. But the tradeoffs are increasingly confusing, complex, and challenging to manage. For example, workloads can change faster than the time it takes to churn out customized designs. In addition, the AI-specific processes may ex... » read more

AI Drives Need For Optical Interconnects In Data Centers


An explosion of data, driven by more sensors everywhere and the inclusion of AI/ML in just about everything, is ratcheting up the pressure on data centers to leverage optical interconnects to speed up data throughput and reduce latency. Optical communication has been in use for several decades, starting with long-haul communications, and evolving from there to connect external storage to ser... » read more

Finding the Scope of CXL-Enabled Tiered Memory System in Production


This new technical paper titled "TPP: Transparent Page Placement for CXL-Enabled Tiered Memory" is presented by researchers at University of Michigan and Meta Inc. Abstract (partial) "We propose a novel OS-level application-transparent page placement mechanism (TPP) for efficient memory management. TPP employs a lightweight mechanism to identify and place hot and cold pages to appropriate... » read more
