New comment by synthos in "Rust compiler performance"

synthos — Thu, 12 Jun 2025 20:17:05 +0000

Regarding AVX: could rust be compiled with different symbols that target different x64 instruction sets, then at runtime choose the symbol set that is the more performant for that architecture?

At least 'minimal human contribution' in the first revision. So scan read it as it revised the book.

I do find it amusing to think that people might just ask an AI to summarize the book instead of actually reading it. Maybe even 'review' it as well.

The future will have authenticity in short supply

Afaik mojo allows for this with the autotuning capability and metaprogramming

What data type/precision? How much parallelism versus iterative? Is this fully in fabric or part of a SoC? Easy to get mired in many details.

HW design has so many degrees of freedom which makes it fun but challenging.

What specific topics are you trying to address with this?

Newton Raphson could be used to calculate a reciprocal. (in a bit width larger than 8). If starting from a good reciprocal approximation, convergence to bit accurate reciprocal should not take many iterations. Then multiply the reciprocal with the numerator to perform the divide

I worked on an automotive FMCW LiDAR that didn't quite make it to market. Cool technology but it was difficult to scale the cost down, which is pretty important for automotive. Margins are very low in that market

It's also, if not more so, a factor of transistor voltage. 1.1V transistors are less prone to upset events than 0.7V. It's possible (assumption, here) that some 3+ volt circuits are still used for critical components of the system

Hi, Could you please elaborate on your original problem?

The binaries your Bazel system built could not be run unless the runtime environment matched the build environment?

It's a perfect time for Matt Colville's MCDM RPG to be announced. It's on backerkit and people are clearly eager for something different. The crowdfunding is at 4x funding and climbing

Definitely buybait and a shame that a blatant advertisement has made to YC news front page. What's next? Novelty toothpaste for nerds?

If there _was_ a good reason to fire Sam, and the board had appropriately and clearly communicated their decision, I think less of the staff would have signed a the petition to walk. From the public's perspective, and probably most rank and file employees, this decision came from left field and had no logic behind it. The waffling and back peddling that followed certainly didn't help perception

nod.ai was just acquired by AMD for a chunk of money. I expect they hope to find a similar exit once they can show an end-to-end product: Take a model written in Pytorch, upcast it to mojo, and put it through their unified compiler stack to accelerate on

I think LiFi or something similar has the great potential for VR/AR headset connectivity. With a high bandwidth, low latency link, you could have an untethered experience without the weight and heat of compute and processing in the headset.
