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 protections are hardware implemented and cannot be forged in software. And this all has to work for whole-system executions, not just the C-language portion of user processes.

This talk originated from my updates to Systems Performance 2nd Edition , and this was the first time I've given this talk in person! CXL in a way allows a custom memory controller to be added to a system, to increase memory capacity, bandwidth, and overall performance. Or even on a plane. It was a great privilege.

Eric asked me to give one of the keynotes at the end of the first day, and invited local Denver people to join the conference for an AI focused meetup that included the final three keynotes, the drinks and snacks reception and some additional talks in the evening. There are already a few hundred AI authored books that have been published.

CLI tools The Cassandra systems were EC2 virtual machine (Xen) instances. Was there some other program consuming CPU, like a misbehaving Ubuntu service that wasn't in CentOS? As a Xen guest, this profile was gathered using perf(1) and the kernel's software cpu-clock soft interrupts, not the hardware NMI.

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. The probe is BEGIN , a special probe that runs at the beginning of the program (like awk). system(".")

Photo by Adrian I spent six years at Cambridge Consultants, building some interesting systems, managing our Sun workstations and learning a lot, but by then Sun had opened a sales office across the street, and I wanted to find out what they were going to release next, before everyone else. as a result there were product and messaging changes.

In such scenarios, scalability or scaling is widely used to indicate the ability of hardware and software to deliver greater computational power when the amount of resources is increased. Consider a program that takes 20 hours to run using a single processor core. communication and load-balancing in MPI-parallelized programs).

As you may recall, back in SQL Server 2016 SP1, they opened up all of the programming surface features to all editions, and many (but certainly not all) of the performance and availability features. I also feel like Enterprise customers tend to already have more and better hardware to throw at the problem than smaller shops can afford.
