    That was brilliant, and answers the questions in my mind before even asking (about using multiple accelerators). Thank you guys

    What I would like to know is if this standard could help multiple GPUs share a workload in a scalable and low latency way that would improve on what is possible with SLI or Crossfire.

    Nice short tutorial ! I used to work few cubes from Gary at G*, he always explains simplified at any level. Thanks Gary.

    Have some queries:
    1. How does CXL achieve low latency? Is it by introducing the device biases and multiplexing three different sub protocols?
    2. What do you mean by dis-aggregation? How does CXL solve this problem?

      1. Low latency: In comparison to the existing cache/mem protocols PCIe link is much faster
      2. Dis-aggregation of the workload from CPU to accelerators

      There is nothing special for low latency in the protocol, it's just the way you access data.
      For a DMA operation, instead of reading the DDR, you read the cache that has a lower read latency.
      It's a fake low latency characteristic.

    we can achieve Gen1 --> Gen3 speed without going to Gen5 in CXL ?

      @sumankumarpatra7115 4 ปีที่แล้ว

      Yes...But it will, in application, defeat the purpose of high bandwidth

      Yes. Gen3 and above
