objdump and just look for the function names. Autovectorization is about the only curve-ball I would expect, but I haven't seen compilers being especially smart about the pipeline or SIMD.

To be clear, are you trying to point out that their charts look like in-order modelling on an out-of-order CPU? Sequential dependencies, especially those existing in looping calculations, turn out-of-order execution into in-order execution.

The author optimized a Taylor series expansion that is way more generic than just a sin/cos function, and they explained why, at the atomic level of data dependency in the pipeline, their optimization worked.

If you need a result to perform the next operation, you have something greater than a RAW hazard. RAW is not necessarily guaranteed to stall whereas a dependency in the result, regardless of the register it's supposed to land in, can&

I had to check the article date twice. Seems old and kind of just a rant. Just be glad you're not still messing with XFree86 modeline settings or whatever. Asus makes high quality products at a good price. Their Zenbook line might h

This is normally the kind of question I ask about anything involving HTML/CSS only or JS only =D PoC's based on low-level concepts are the ones that make you curious about everything from top to bottom. Even though assembly is t

I wish they would just re-implement the whole thing on top of a hybrid API with reference FOSS implementations of web client servers and client apps so that programmers can pick-and-choose how much PaaS they need. Please get the "apps

Oh Shopify. One of the many reasons I support FOSS business models for anything programmers need to touch. Offline will definitely be an improvement.

The lightweight part is pretty useful. LXC is definitely overkill. I don't want to have to bridge my graphics and networking over so that I can run programs against different versions of libraries. Going more lightweight, if I'

The whole cyber arms-race makes no sense. It's like mutually assured destruction when you have the capability to remotely dismantle each others' nukes by publishing your designs.

I do flat-rate projects like this using a library that I have to fill in gaps myself. Even in the context of very high unpredictability, I have to make good predictions else suffer low compensation exactly like the parent poster did. I lik

What I find most hilarious in hindsight is that the parent poster, myself, and everyone in this thread except the article poster seemed to miss the first line about "ironic answer" yet we're all insisting that it was a seriou

What I really want to say is that you can turn my kernel calls into JSON-RPC when you pry my ARM assembler from my cold, dead fingers.

I'm thinking the next big step is to build ASIC's with hierarchical memory sub-systems that can quickly load and execute either x86 or ARM instructions, kind of like binary run-times implemented in hardware, and then boot operatin
