Can that be split across multiple GPUs? i.e. what if I have 4xV100-DGXS-32GBs?

I'm curious if anyone knows how the new threadpool primitives introduced in Vista fair in Wine/proton? Do games simply not use any of these APIs? (That's surprisingly, the threadpool stuff is easily one of the best pieces w

Want to elaborate more on Chapel? I’ve recently being tasked with integrating Chapel into our system and it’s quite interesting.

That’s not how ATC works. First come, first served.

by trentnelson 3y ago
“Visual approaches in use” is less labor intensive for ATC than instrument approaches in visual conditions. It also allows for higher flow. Bit on the hyperbolic side implying visual approaches push the system to the breaking point.

ATC works on a first come, first served basis. (Unless you’re Air Force 1/2, or a survival flight, or declare an emergency.) So just being in the system hours beforehand doesn’t really mean much. ATC don’t plan ahead based on what’s

Oh, absolutely. I more meant from the "CEO of Microsoft" perspective; I guess I could ask Ballmer the same thing if he did an AMA.

I keep meaning to try ask Bill Gates this question whenever he does one of his Reddit AMAs: Bill, what are you most proud of out of the following two: 1. Getting Cutler to come over from DEC and spearhead NT. 2. Committing to backwards comp

Fantastic book that had a huge impact on me. I reached out to the author on Twitter way back to tell him how much I liked it, and he was really nice.

One of the most pivotal moments in my software engineering career came from reading the leaked NT source code (6-7 years ago) in conjunction with reading the Showstopper[1] book. The NT leak is particularly fascinating because it included

Interesting that Cutler was working on circuit-oriented stuff that late in the 80s? Or was this invented much earlier, just patented later? He was courted by Microsoft in '89, so this patent looks like it went through after he'd

Cutler retired?!

Could you not also see an impact to run times? If algorithm A draws 100W and runs in 10 seconds, and algo B draws 200W… shouldn’t it be very much sub 10 seconds to warrant being called a better algorithm?

by trentnelson 3y ago
100% agree! I use whatever tool in the C toolbox results in the easiest-to-(read|grok) code, which means tons of anonymous union/struct “abuse”, bit fields, function pointer typedefs, strictly adhering to “Cutler Normal Form”.

Getting performance out of Alphas usually depended heavily on the compiler, and, really, only the DEC compiler really made it shine. GCC was notoriously bad at generating optimized binaries (circa ~2.95), at least compared to compiling the

I remember seeing someone link to that scene recently as a joke on Twitter (about Twitter trying to explain Twitter Blue). Within a few days I’d watched the entire series… absolutely phenomenal show. Edit: ah I actually saw the prior scene

You can pry vim from my cold dead hands, unless I have to write C# or Java, and then, yeah, IDE all the way.

I feel like if you're bothered simply by the existence of the registry, Windows isn't really for you. I get it, a little bit -- the OOM killer on Linux just boggles my mind, but once you view in context, you can appreciate how we

It runs really, really smoothly on my Xbox Series X. I'd arguably say even smoother than my OC'd 10900K + RTX 3090 PC.

As much as I love Cutler... I'm also impressed a news website that existed in 1999 still exists today in 2021!
