How PCIe 5 and its Smart Friends Will Change Solution Acceleration

Nice article by Scott Schweitzer, Xilinx

Keynotes:

🥦PCI-E Gen5 offers not only throughput bandwidth doubling, but also Compute Express Link (CXL) and a Cache Coherent Interconnect for Accelerators (CCIX) promise to create efficient communication between CPUs and accelerators like SmartNIC or co-processors.

🕸 CCIX configurations include direct attached, switched topologies, and hybrid daisy chain.  it can take memory from different devices, each with varying performance characteristics, pool it together, and map it into a single non-uniform memory access (NUMA) architecture. Then it establishes a Virtual Address space, enabling all of the devices in this pool access to the full range of NUMA memory

🥥 SmartSSDs, also known as computational storage, place a computing device, often an FPGA accelerator, alongside the storage controller within a solid-state drive. This enables the computing device in the SmartSSD to operate on data as it enters and exits the drive, potentially redefining both how data is accessed and stored.

👩‍🔬 SmartNICs, are a special class of accelerators that sit at the nexus between the PCIe bus and the external network. While SmartSSDs place computing close to data, SmartNICs place computing close to the network

👩‍👩‍👧‍👧 SmartNICs and DPUs (data processing units) that leverage PCIe 5 and CXL or CCIX will offer us richly interconnected accelerators that will enable the development of complex and highly performant solutions
