How to Partition Resources and Eliminate (Most) OS Abstractions for Fast I/O
- 👤 Speaker: Pekka Enberg (University of Helsinki)

Abstract
Abstract:
I/O is getting faster in servers that have fast programmable NICs and non-volatile main memory operating close to the speed of DRAM , but single-threaded CPU speeds have stagnated. Applications cannot take advantage of modern hardware capabilities when using interfaces built around abstractions that assume I/O to be slow. In this talk, we present the parakernel model, which aims to move the OS out of the way, to allow applications to take advantage of today’s fast I/O devices.
Bio: Pekka Enberg is a PhD student at the University of Helsinki, working on operating systems and application architecture to take advantage of fast I/O devices. He has previously worked on the Linux kernel, the OSv unikernel, and is now working on ScyllaDB and Seastar.
Series This talk is part of the Computer Laboratory Systems Research Group Seminar series.
