The system is a new design by Rackspace and its OCP partners that combines the OpenPOWER, POWER8, and Open Compute design principles, targeted to run OpenStack services.

37 IBM Memory Technology Innovation Utilizing Altera FPGAs Collaborators: IBM, Altera IBM is working with partners across the industry to innovate on the Power memory bus. Utilizing an Altera FPGA, the Con Tutto card enables in-system experimentation with new memory technologies as well as combinations of Flash and DRAM. Additionally, acceleration prototyping on the POWER memory bus is explored.

39 Le développement du POWER9 a démarré Each [Summit] node will contain multiple IBM POWER9 CPUs and Nvidia Volta GPUs all connected together with NVIDIA s high-speed NVLink. Each node will have over half a terabyte of coherent memory (high bandwidth memory plus DDR4) addressable by all CPUs and GPUs, plus 800GB of non-volatile RAM that can be used as a burst buffer or as extended memory. To provide a high rate of I/O throughput, the nodes will be connected in a non-blocking fat-tree using a dual-rail Mellanox EDR InfiniBand interconnect.
