GPU Rowhammer Attacks Beyond Data Corruption (U. of Toronto)


A new technical paper, "GPUBreach: Privilege Escalation Attacks via GPU Rowhammer," was published by researchers at University of Toronto. Summary "GPUBreach shows that GPU Rowhammer attacks can move beyond data corruption to real privilege escalation. By corrupting GPU page tables, an unprivileged CUDA kernel can gain arbitrary GPU memory read/write, and then chain that capability into CPU... » read more

All AI Data Center Interconnects Will Be Optical Within 5 Years


I spent several days at OFC (Optical Fiber Communications Conference) 2026 in LA. The crowds were huge and the enthusiasm intense. Long-time attendees noted the shift from telecom to data center AI in just a few years. Nvidia GTC 2026 took place simultaneously in San Jose. OFC and GTC are entangled because data center AI needs optical interconnect to keep compute fed. Optical interconnect... » read more

Chip Industry Week In Review


Deals IBM and Arm are collaborating on a new dual‑architecture hardware aimed at enterprise AI and data-intensive workloads, using virtualization to boost reliability, security, scalability, and software compatibility. The goal, according to an IBM spokesperson, is to deliver side-by-side deployments of S390x-Linux and Arm-Linux virtual machines in a single kernel-based hypervisor. Nv... » read more

Chip Industry Week In Review


Arm uncorked its first internally developed CPU chip this week, aimed squarely at the agentic AI data center market. Arm CEO Rene Haas (pictured) emphasized the CPU's power efficiency and performance/watt compared to other AI processor architectures. "We are obsessed with efficiency, and if you think about one of the biggest appeals that Arm has had over the years, it is power profile," he ... » read more

Chip Industry Week In Review


War impacts The Iran War's toll on the chip industry is widening. Over 95% of Taiwan's energy is imported, causing the country to secure alternative sources. Korea is also heavily dependent on energy imports from the Middle East. Shortages of key materials are cropping up everywhere. Helium from Qatar, the second largest producer behind the U.S., is constrained by hostilities in the Per... » read more

Advanced Packaging Limits Come Into Focus


Key Takeaways: Packaging is now a performance variable. Substrate, bonding, and process sequence determine what can be built at scale. Warpage underlies most advanced packaging failures and gets harder to control as package sizes grow. Every proposed solution, such as glass, panel processing, and backside power, solves one problem while creating another. Moore's Law has shif... » read more

Replay‑based Validation as a Scalable Methodology for Chiplet‑based Systems (Intel, Synopsys)


A new technical paper, "ODIN-Based CPU-GPU Architecture with Replay-Driven Simulation and Emulation," was published by researchers at Intel, Nvidia and Synopsys. Abstract "Integration of CPU and GPU technologies is a key enabler for modern AI and graphics workloads, combining control-oriented processing with massive parallel compute capability. As systems evolve toward chiplet-based archite... » read more

Chip Industry Week In Review


Disruptions caused by the Iran conflict have taken about one third of the global helium supply off the market, an essential gas for semiconductor manufacturing, reports the World Economic Forum. Other potential impacts for the chip industry include bromine and other chemical shortages, logistical disruptions, and higher energy prices incurred by fabs in Asia. Top Deals IBM and Lam R... » read more
