title: "Intel VCA 2: making an end-of-life accelerator useful again"
abstract: >-
  Reverse-engineering notes, measurements and working code for the Intel
  Visual Compute Accelerator 2 (VCA1585LMV), a discontinued PCIe card with
  three Xeon E3-1585L v5 nodes and three Iris Pro P580 GPUs. Covers a tuned
  OpenCL GEMM (1.36 TFLOP/s per card), the undocumented PLX DMA engine
  (144x faster node reads, 4.4 GB/s CPU-free node-to-node), a reproducible
  Ubuntu 22.04 node image on Intel's 4.14 kernel, thermal and power
  characterisation with printable fan shrouds, and applications built on
  the card: a local agent-memory service and a video render farm.
