That's not entirely true. AVX from the beginning (introduced with Sandy Bridge), not AVX2 (introduced with Haswell), contains 128-bit instructions as well, and these are what's being used in the article (e.g. vpermilps).

The only Xeon Phi products to be available in PCIe form are the first-gen KNC cards. These are not Atom-based, they do not share the x86_64 ABI, and the only effective toolchain for them is older versions of the proprietary Intel compiler.

The answer is simple but impractical: Grossly overbuild the structure, so that it is lightly stressed. Don't use any reinforcing material within the concrete (much of the damage that happens to a modern reinforced concrete structure is

I think, quite frankly, AMD ceded the AI accelerator market to Nvidia the day they decided not to offer consistent compute-API support throughout their product range. ROCm support is limited to a very select number of flagship products, and

You're making my point for me. Recent Pixels are basically the only well-known Android phones in the US market that _aren't_ using Qualcomm SoCs, and they're a very small share of the US market. That gives Qualcomm more lever

So, to be clear, you appear to either (a) have a case where there are significant behavior differences between passing by mutable reference versus pointer (and thus _need_ to use a pointer), or (b) are relying on operations to certain types
224.
by cpgxiii 4y ago
That only goes so far - without reasonable method names you still don't know if the operation actually mutates the parameter, e.g. in void func(ParamType* param) { ... auto res_1 = param->Operation1(1); auto res_2 =
225.
by cpgxiii 4y ago
Code following this style (e.g. lots of code following GSG or GSG-derived styles), tends to have large amounts of void func(ParamType* param) { assert(param != nullptr); ... } because passing via pointer introduced undesire

The problem with this is that once you get any deeper than the first call, that helpful "&arg" goes away and it's just "arg". I would argue this sometimes-there single character is incredibly brittle for the cla

There's an interface for debugging many (not all) Intel machines via USB that's been around for years. Needs to be enabled in firmware first, given the obvious security implications.

A variation of this are dynamic spatially-hashed voxel grids, where the outer grid is spatially hashed and the grid elements are stored (as needed) as dense voxel grids. The advantages of this are that you get voxel grid-like behavior over
