Intel's GPUs aren't exactly known for stellar performance, but I'm pretty sure that's old info even for Intel. Certainly this kind of parsing hasn't been required on AMD and Nvidia GPUs' 3D engines for almost t

Schemes like that are in fact implemented by some devices on top of the existing PCIe interrupt mechanism. For example, GPUs have many different interrupt sources, so a common technique is to have an interrupt ring buffer that the GPU write

I don't know what kind of conferences you attend, but I've never attended one where people got black-out drunk, nor have I attended any with my partner. On the other hand, I have attended conferences where we were specifically w

In fairness, the context of the Ts'o email seems to be conference organization, and it points out that large fractions of the rape statistics are made out of domestic abuse and drunk undergrads. Neither of those seem particularly relev

You probably mean well, but this is dangerous misinformation. There are no popular public-key encryption schemes that are safe against quantum computing. The only popular public-key encryption schemes are based on RSA and ECC, both of w

First of all, the paper that this article is reporting on doesn't actually prove a separation between quantum and classical algorithms at all. It's an oracle separation result, which makes it an important result in complexity theo

And then there's King's Letter from a Birmingham Jail: https://www.africa.upenn.edu/Articles_Gen/Letter_Birmingham.... Sometimes you need to make waves in order to advance a cause. Now that doesn't mean

Yeah, this thread has degraded extremely rapidly in terms of comments. And luckily it just disappeared off the front page :)

John Carmack's talks, especially the ones from his id days at QuakeCon. Watching somebody get on stage and just talk for hours in detail without notes about a whole range of technical topics that they mastered and enjoy is pretty inspi

I recall reading that it's not that those 12 bits are explicitly asserted, but rather that the CS descriptor after reset is in an "unreal mode". After all, x86 segment descriptors consist not just of their numeric value, but

Coverity is pretty good, but shows quite a lot of false positives in my experience. This may obviously depend on the project, of course. What I really wish for is an easily understandable way to teach these advanced static analysis tools ab

> The hardest part of figuring out why a particular path is violating timing is not because of the reporting of the tools, it's because a blob of logic has been flattened and merged into a LUT, and it's hard to identify how a L

There's potentially tremendous value in having an open bitstream. To get the most out of hardware, you need feedback on how many LUTs each part of your design uses, where the critical dependencies are for the achievable clock rates, an

RT cores are different because raytracing wants AoS (array of structures) rather than SoA (structure of arrays). Let's look at the ALU perspective. Normal shader cores are essentially SoA: all ALU operations operate on 32 (NVidia) or 6

This is a very interesting link. Note that the strongest decline in energy intensity in the disaggregated graph at the bottom is in transportation. That certainly speaks for efficiency as an explanation. As for the growth story, well. The o

It might be possible to find and exploit a buffer overflow by impersonating a cell phone tower. Not exactly trivial to pull off, but certainly not a priori impossible.

Aside from the callousness of your remarks, you do realize that having 19 bones isn't an absolute, right? Once there are only 19 dogs left, the number of bones will simply be reduced to (slightly more than) 18, because the prevailing i

Yes, there's frictional unemployment. How much, though? This may differ by country, but you typically only show up in the numbers if you were fired. After all, if you quit your job, you aren't involuntarily unemployed, which is
