  Processing-in-Memory: UPMEM, Samsung HBM-PIM, and the Near-Data Computing Paradigm

  2025-02-10

  How moving compute to where the bits live rewrites the rules of memory-bound computation, from UPMEM's DRAM-scale PIM to Samsung's HBM-PIM and the programming model that still keeps us up at night.
