Yes, exactly. That is what I usually do.

My experience with benchmarking is that the benchmark program must actually do something with the result (like, printing it). Not only because you cannot trust a benchmark to do self-validation, but also because you otherwise end up figh

Couldn't a bytecode format have the same problem? Probably not with respect to parsing, but the semantics could still differ.

Well, I still have a year left on my PhD, and I hope (with some reason) to get funding to continue after that. But I must emphasize that the language is still a little young and raw.

I'm not sure why bytecode is supposed to be significantly better than storing the shaders as strings. Sure, you get rid of a complex parser and can more easily use it as a compiler target, but the core problem remains: the compiler ca

What kind of compiler technology? I've seen it mentioned that it uses a nanopass design, but that's more of a development strategy than something that results in performant code or low compile times.

Some of you may have seen this last week on Reddit. Since then, we improved the website with a gaussian blur stencil example[0], a stencil performance graph[1], and an article on Pygame interop[2]. [0]: http://futhark-lang.org&#

Does the Q/K implementation actually execute in parallel? I've always had a hard time figuring out exactly why K is supposed to be so fast (except for column stores, interpreter fitting in L1 cache, and fast hand-written primitiv

I find it interesting that NVIDIA has been decreasing the number of CUDA cores per streaming multiprocessor (SM) in each successive architecture, while increasing the number of streaming multiprocessors. It makes each SM look more like a C

Not particularly. Most of my GPU experience is with OpenCL, which does not have the OpenGL-related problems that Vulkan is supposed to solve.

One significant benefit of CPU SIMD is that you also do not need to manage temperamental GPUs and GPU drivers. The CPU programming experience is much nicer, the infrastructure more robust, and you can generally expect some sort of SIMD sup

This is both BSD- and GPL-incompatible, which has all sorts of potential ramifications. Particularly the GPL-incompatibility prevents you from including GPL-licensed code. Although both BSD and GPL already require attribution, so you could

Null is wrong. It was implemented because it was easy, as it maps directly to how object references are typically implemented in memory: http://lambda-the-ultimate.org/node/3186

Any setting a user must adjust or manage to make things work is a bug. Everything must work instantly and reliably in any minimally functional environment, and installation must be single-step. This has its own problems, as you risk build

Is that a common piece of snark in the community? I know that Theo was one of the NetBSD founders, but so were the people who forced him out.

Not much. At the student revue last year, we had filled a thermos with dry ice, closed it up, and forgot about it on stage overnight. At some point during the night, it blew off the plastic valve at the top, which was ruined, but the meta

I got a ThinkPad X250 a few weeks ago. Originally I was hesitant, as it is also limited to 8GiB of memory, but I realised that development need not actually use more than that (and indeed, I never do). I basically need to run just Emacs,

It's not really a license at that point, as I don't think you can impose obligations upon yourself that easily - at least not ones that have legal weight. This seems more like a statement of intent, which is nice I guess. But sti

Point of correction: Unreal Engine is not open source, the source is merely available for perusal. You still need a license for most uses.

You have to remember that Deep Blue was not a top-of-the-line supercomputer in 1997. It was a large machine for sure, but the software made it a chess champion, not just the raw hardware. Many 1997-era computers were faster.
