It sounds like you're talking about unsophisticated sparse data structures, such as `std::list`, not the aforementioned chained memory allocation data structures which optimize for memory latency and vectorizability while retaining poi

Cling has been largely upstreamed as `clang-repl`. All distributions of clang+tools has it now, and unlike Cling this supports the latest Clang features. However Cling still has some special features for GPGPU that `clang-repl` doesn't

I'm sure this presenter understands the nuance, but I think it's worth mentioning that linked lists are important for many highly efficient data structures and algorithms. For instance, see https://plflib.org/ Poo

AMD's debuggers and profilers let you disassemble kernel/shader machine code and introspect registers and instruction latency. That's something at least that Nvidia doesn't do with Nsight tools.

OpenCL isn't very useful now that we have Vulkan. Its biggest advantage is that there exist C++ compilers for its kernels. But AMD's OpenCL runtime inserts excessive memory barriers not required by the spec (they won't fix th

I really doubt that, personally. In that area maybe between 5x and 10x these figures would seem plausible to me.

Correction, I actually just tried this. The wrapper does not work in GCC, but it does in Clang. https://godbolt.org/z/d3jMo36WY

That's interesting. It also looks like with the `__restrict` specifier ( https://godbolt.org/z/cvaYoc6zh ), the clang code is similar regarding the matrix multiplication. The body of the vectorized loop itself looks

I used Dvorak for awhile. It's okay, at least better than QWERTY. But it's super old, and keyboard layouts post-Colemak take advantage of rolling bigrams and trigrams, unlike Dvorak. I use Hands Down now. https://sites.

Multiple-aliasing cannot exist in a language without reference semantics, such as Val (or whatever its new name is).

I've never had issues with it, personally. In what way does it not work?

Did they ever get Nvidia hardware working without GlibC? A quick DuckDuckGo search suggests that's still not supported.

Clang has a statement attribute `[[clang::always_inline]]` that automates this at a call site, but GCC only has a function attribute for it. You could wrap the function in a `[[gnu::flatten]]` function that takes the callable as a non-type

Every release of C++ since 11 has relaxed limitations on `constexpr`, and several relaxed limitations on `template`. Many other features have had various rules relaxed in certain releases, including `for` loops, lambdas, labels, moves, and

My understanding is that it's simply historically fallen into the niche. Lua early on was relatively easy to embed in C codebases, making it a natural fit for scripting C (or C++) game engines and their editors. So many hugely popular

North Korea actually doesn't adhere to the kernel's GPL license. I wonder if anyone will ever be brave enough to sue them for copyright infringement.

Exa is an interactive utility. It doesn't make much sense to put it in a script like that. If you were to use rg or ug instead of grep, branching like that would probably be worthwhile, though.

I'm fairly familiar with both V and D (even made some minor contributions to the V compiler), and I can't think of a single notable feature that isn't also available in D. V has a more modern and straightforward syntax, but t
