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.
