DescriptionThe Open Coherent Accelerator Processor Interface (OpenCAPI) is an industry standard architecture targeted for emerging accelerator solutions and workloads. OpenCAPI enables the development of host-agnostic devices which can coherently connect to any CPU which supports the OpenCAPI standard, providing the device with the capability to coherently cache host memory to facilitate faster accelerator execution. OpenCAPI utilizes high-frequency differential signaling technology while providing high bandwidth in addition to low latency needed by advanced accelerators. OpenCAPI encapsulates the serializing cache access and address translation constructs in high speed host silicon technology to minimize SW path length and design complexity in attached acceleration silicon such as FPGAs and foundry ASICs. OpenCAPI architecturally ties together Transaction Layer, Data Link Layer, and Physical Layer attributes to enable high bandwidth, highly parallel exploitation of attached silicon. Finally, this session will also cover all the OpenCAPI enabled servers as well as the ecosystem that surrounds OpenCAPI.
