  12. 12. ENGINEERS AND DEVICES WORKING TOGETHER HPC - Why Linaro? ● HPC has a large (and growing) open source component ● Some customers require multiple tools chains: proprietary and/or open source ● Library optimisations that benefit all micro-architectures ● A place to co-develop ● Root the foundations to make choice easier SoCs System Integrators System Vendors Commercial Users Research Users Govt Projects ODMs Distros Hyperscaler s Collaborate Linaro
  13. 13. ENGINEERS AND DEVICES WORKING TOGETHER Collaborative project building on the work of the Linaro Enterprise Group (LEG) Leverage the Linaro Developer Cloud and other services to develop cost-effective Cloud-based HPC development frameworks and generate reference implementations to accelerate Lower deployment & management barriers Machine learning and Deep learning are both critical to the future of HPC. Specifically as the path toward exascale computing. Driving engineering in HPDA and Machine learning algorithms will aid the success of organizations to fully capitalize on these technologies. Enable the data-driven economy HPC Special Interest Group Identify and adopt standards in to make HPC deployment on Arm a commercial imperative. Develop real-world use cases that reap the benefits of Arm while ensuring interoperability, modularization, orchestration. Driving enterprise-class, open-source HPC development on Arm Members determine work completed by engineering resources while advisory board provides subject matter expertise on HPC requirements and guidance and feedback on ongoing HPC SIG strategic direction and roadmap Member-driven with Advisory Board HPC
