HPE on Tuesday introduced the world's largest single-memory computer as part of The Machine, its research project into memory-driven computing. The computer has 160 T-bytes of memory, and HPE expects the architecture to allow memory to scale up to 4.096 yottabytes. The memory is spread across 40 physical nodes that are interconnected using a high-performance fabric protocol. The computer runs on an optimized Linux-based operating system running ThunderX2, Cavium's flagship second-generation dual socket-capable ARMv8-A workload optimized SoC.
