AWS Graviton2); for memory with the arrival of DDR5 and High Bandwidth Memory (HBM) on-processor; for storage including new uses for 3D Xpoint as a 3D NAND accelerator; for networking with the rise of QUIC and eXpress Data Path (XDP); and so on. In case you are interested, at the same conference I also gave a talk on [BPF Internals].

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.

The success of our early results with the Dynamo database encouraged us to write Amazon's Dynamo whitepaper and share it at the 2007 ACM Symposium on Operating Systems Principles (SOSP conference), so that others in the industry could benefit.

I don’t need more bandwidth for video conferences or movies, but I would like to be able to download operating system updates and other large items in seconds rather than minutes. But that’s also a problem that 5G vendors could solve; virtual LANs ( VLANs ) are hardly a new concept. I do regular backups, but I know I’m the exception.

The Morning Paper

MAY 27, 2019

Last week we saw the benefits of rethinking memory and pointer models at the hardware level when it came to object storage and compression ( Zippads ). The work includes changes to the CHERI ISA, the C compiler, the C language runtime, the virtual memory APIs, and the CheriBSD kernel. ASPLOS’19.

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. USENIX ATC is a top-tier venue with a broad range of systems research papers from both industry and academia. Heterogeneous ISA. Final words.

Our team also produced The Guide to High Availability by storage expert Jeannie Johnstone Kobert, Sun Cluster Environment by Enrique Vargas, Solaris PC Netlink by Don Devitt (we had a great team outing near Boston on his sailboat), and several other books. Nothing went wrong, I got to see some events, and got very cold at times.

I've suggested adding a command to docker to make listing at least the top-level PIDs in containers easier. ## Virtual Machines The two main technologies on Linux are Xen and KVM (and there's Bhyve for BSD). What happens if processes really do try to populate all that virtual memory?
