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. At hardware reset the boot code is granted maximally permissive architectural capabilities.

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.

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).

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. Hardware engineers design and implement solutions in RTL, while software engineers attempt to solve the problem either at the OS or application level. Discounting the Past.

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). was just released.

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.
