  • Despite the Pandemic, IBM POWER10 Is on the Near Horizon By
    Feb. 9, 2021 Despite the Pandemic, IBM POWER10 is on the Near Horizon By Jean S. Bozman Even in the teeth of the pandemic, IBM is expected to deliver its POWER10 processors in calendar 2021, continuing its drive to place a new generation of POWER microprocessor engines in the world’s cloud data centers. Cloud migrations, accelerated by the pandemic’s impact on business worldwide, are making it possible to deploy many types of CPUs and GPUs in the cloud infrastructure, which is dominated by servers based on Intel x86 processors. POWER10 processors are aimed at running in the hybrid cloud, supporting AI/ML analytics applied to enterprise applications and scalable enterprise workloads (e.g., SAP, SAS). That strongly aligns the POWER10 processors with IBM’s strategic marketing priorities for hybrid cloud and AI/ML. The POWER10’s life in the extended hybrid cloud, coexisting with other types of processors from Intel and AMD, will be possible because cloud infrastructure supports mixed hardware types in a scale-out hyperscale world where clusters are the cloud’s go-to resources for running specific workloads. POWER10 is positioned for use in highly scalable (scale-up) systems – and in optimized scale-out cloud-native workloads. So, it is intended for supporting workloads that are migrating from the enterprise data center into the hybrid cloud. The emphasis is on faster processing of enterprise applications; support for accelerated AI analytics; support for multi-PB (petabyte) memory clusters, embedded math acceleration and extremely high security. How Will POWER10 Fit Into Hybrid Clouds? POWER10’s presence in the cloud is significant, because IBM’s stated corporate strategy focuses on hybrid clouds and AI.

    OpenCAPI and its Roadmap Myron Slota, President OpenCAPISpeaker name, Consortium Title Company/Organization Name Join the Conversation #OpenPOWERSummit Industry Collaboration and Innovation OpenCAPI and its Roadmap Topics . Industry Background and its influence on IBM’s IO and microprocessor roadmap . Limitations of CAPI running over PCIe . Creation of the OpenCAPI architecture and its benefits . OpenCAPI Consortium . Potential solutions based on coherent attached accelerators Industry Background that Defined OpenCAPI . Emerging workloads driving computational demand (e.g., AI, cognitive computing) . Moore’s Law not being supported by traditional silicon scaling Computation Data Access . Driving increased dependence on Hardware Acceleration for performance to continue on Moore’s Law • Hyperscale Datacenters and HPC • Require much higher network bandwidth (100 Gb/s -> 200 Gb/s -> 400Gb/s are emerging) • HPC and Artificial Intelligence (deep learning, inferencing) • Need more bandwidth between accelerators and memory • Emerging memory/storage technologies • Driving need for bandwidth with low latency 4 Industry Background that Defined OpenCAPI . Hardware accelerators are defining the attributes required of a high performance bus • Offload the computational demand on the microprocessor – if you are going to use accelerators, the bus needs to handle large amounts of data quickly • Growing demand for network performance and offload Computation Data Access • Introduction of device coherency requirements • Emergence of complex storage and memory
