Computing Performance 2021: What's On the Horizon
Please log in to watch this conference skillscast.
The pursuit of faster performance in computing is the driving reason for many new technologies and updates. This talk discusses performance improvements now underway that you will likely be adopting soon, for processors (including 3D stacking and cloud vendor CPUs), memory (including DDR5 and high-bandwidth memory [HBM]), disks (including 3D Xpoint as a 3D NAND accelerator), networking (including QUIC and eXpress Data Path [XDP]), runtimes, hypervisors, and more. The future of performance is increasingly cloud-based, with hardware hypervisors and custom processors, meaningful observability of everything down to cycle stalls (even as cloud guests), and high-speed syscall-avoiding applications that use eBPF, FPGAs, and io_uring. The talk also discusses where future performance improvements might be expected, with predictions for new technologies.
