It's an exciting time for developments in computer performance, not just for the BPF technology (which I often [write about]) but also for processors with 3D stacking and cloud vendor CPUs (e.g., This was a chance to talk about other things I've been working on, such as the present and future of hardware performance.

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. What about security?

People have a myriad of biases that influence how we think about problems and he developed models to quantify the impact of behavior on economic theories. Hardware engineers design and implement solutions in RTL, while software engineers attempt to solve the problem either at the OS or application level.
