The Morning Paper

DECEMBER 8, 2019

At the start of November I was privileged to attend HPTS (the High Performance Transaction Systems) conference in Asilomar. On the last morning of the conference Daniel Bittman presented some of the work being done in the context of the Twizzler OS project to explore new programming models for NVM.

It is much more difficult to publish truly risky, revolutionary research due to implicit filters in what gets funded and what makes it past a program committee. Virtualization, for instance, was being addressed by IBM in the 1960s. At other times, the PC’s response is to push the paper to another conference.

bpftrace uses BPF (Berkeley Packet Filter), an in-kernel execution engine that processes a virtual instruction set. BPF has been extended (aka eBPF) in recent years for providing a safe way to extend kernel functionality, and has become a hot topic in systems engineering, with at least 24 talks on BPF at the last Linux Plumber's conference.

This blog post gives a glimpse of the computer systems research papers presented at the USENIX Annual Technical Conference (ATC) 2019, with an emphasis on systems that use new hardware architectures. GAIA proposed to expand the OS page cache into accelerator memory. ATC ’19 was refreshingly different. Programmable I/O Devices.
