• Cerebras Wafer-Scale Deep Dive — A Whole Model on a Single Chip

  A close look at the design of the Cerebras WSE-3, a single chip carved from an entire wafer. We cover the on-chip SRAM-centric structure that routes around the memory wall, the fault-tolerant design, real-time inference

• The Memory Wall and HBM — The Real Bottleneck That Divides AI Performance

  In an era where compute is cheap and data movement is expensive, the real bottleneck of AI performance is memory. From the memory-wall concept to HBM generations, the roofline model and arithmetic intensity, the KV cache

• In-Memory Computing Principles — Computing Inside the Memory

  A deep look at the principles of compute-in-memory (CIM): computing directly inside memory instead of moving data to a compute unit. We cover solving a matrix multiply in one shot with a crossbar array, the difference be
