GDB tip of the day: `info registers` will show you the contents of general purpose registers, but `info all-registers` will expand the output to floating point registers and CSRs.

“The task the computer designer faces is a complex one: determine what attributes are important for a new computer, then design a computer to maximize performance and energy efficiency while staying within cost, power, and availability constraints.” - Patterson & Hennessy

Feels like Strava is either worthless or intoxicating depending on your personality.

That is to say, to build custom hardware you shouldn’t have to know about gates and transistors, just like you don’t need to know about web servers or even HTML to build a Wordpress site. 4/n

With more and more open source IP becoming available (typically via @risc_v), and non-commercial FPGA toolchains being developed, I’d love to imagine a world in which a scientist can build custom hardware in the same way anyone can build a website. 3/n

Which typically means that their simulation is massively parallelizable, and “gaming” GPUs are the best readily available solution. I’m guessing that there is a lot of performance left on the table because these folks are not, and shouldn’t have to be, chip designers. 2/n

Been talking to a number of folks doing “traditional” science PhDs (biology, physics, chemistry) lately, and their exposure to computation is fascinating to me, particularly how they are leveraging specialized hardware. I hear a lot of “I use gaming PCs for simulations”. 1/n

It’s a great day to run across the state of North Carolina! #BlueRidgeRelay

Thought I had a meeting at 8 AM and needed to get a ton done before it. Turns out it is a few hours from now. Might start scheduling phantom meetings as a productivity hack.
