Ray tracing sound on the GPU (Work in progress). Since the whole game is running on the GPU, I found it convenient to do the sound management and the ray tracing on the GPU as well. Each frame the CPU receives a sound queue from the GPU to process,...

I’ve been really interested in this project since I found it! It runs so fast! By chance is it open source anywhere so I can see how it’s done? It’s amazingly clean, and runs incredibly fast for such a detailed/dense voxel scene on the web!

Thanks for the kind words, but I have no plans of open-sourcing it

Does it introduce any kind of delay on sound playback? I always hear people saying CPU->GPU roundtrips introduce delay (unless you force sync and destroy performance)... Anyway incredible job! I'll keep an eye 👀

@jodemi_ Yeah the GPU->CPU roundtrip adds some delay because it's async, but it shouldn't be too bad. I think the WebAudio API also adds some delay on certain effects, but I'm still too early in the topic to say where the limits and bottlenecks are..:)

would love if you have any resources on sound propagation that you can reccomend for something like this, it sounds great!

I am at the 4th iteration on the pixel inspector and light path debugging tool. Eventually I moved the path collection to the GPU, so I don't have to toggle between CPU and GPU rendering, making the visualization fully interactive.

I tested this on the 4070 Super, and while there is a performance difference, it’s not huge. The GPU also pulls more power on the older driver. If you’re using Path Tracing and have a higher-power 40 series GPU, it’s still worth trying, you might see a bigger performance boost.

We are excited to share a deeper look into the GPU Sharing Platform that will power AI applications on the InfraX V4 DApp. In this demo we showcase a GPU running and completing an image generation task. Our backend successfully leverages this GPU (and CPU) in real time to complete the job, earning the user money, and powering the infraX platform. Here’s how it works 👉 when you connect to the InfraX DApp, our platform automatically detects the GPU on your machine and immediately checks it eligibility and where it can be used. From there, each user dictates exactly how and when they want to contribute their GPU power by setting the days their PC is most available (throughout the night, for example). Additional, each user will be able to pause their GPU's connection to infraX whenever they need to use it locally, resuming with a just a single click. Once activated, your GPU seamlessly plugs into the InfraX network and begins fulfilling compute jobs, earning YOU money. Go on, take the $INFRA pill..

Finally, the first 'stable' release of my Godot fork with GPU agnostic Ray Tracing Global Illumination and Frame Generation. It should also bring some performance improvements in specific areas. It works as a drop-in replacement for Windows and Linux desktop apps. Link below 👇👇👇

Stress testing Metropolis 1998! - Population: 53,500 - CPU FPS: 80 - GPU FPS: 10-80 - RAM: 3,100 MB So: At the moment, the game is GPU bound. I know why and there's a lot of room for improvement. It will involve developing or customizing an existing GPU framework. There's also a lot of room to improve CPU/RAM, but right now it's in an okay place. #gamedev

GPU by hand ✍️ I drew 42 frames to show how a GPU speeds up an array operation of 8 elements in parallel over 4 threads in 2 clock cycles. Below is an overview: CPU • It has one core. • Its global memory has 120 locations (0-119). • To use the GPU, it needs to copy data from the global memory to the GPU. • After GPU is done, it will copy the results back. GPU • It has four cores to run four threads (0-3). • It has a register file of 28 locations (0-27) • This register file has four banks (0-3). • All threads share the same register file. • But they must read/write using the four banks. • Each bank allows 2 reads (Read 0, Read 1) and 1 write in a single clock cycle.

Gpu manufacturers went from selling hardware that did its job at a decent price, to selling you a Gpu that’s a mild upgrade with upscaling features at an inflated price DLSS/FSR/Etc is a crutch being used by game devs to avoid optimization or to shove Ray Tracing I hate it here

I know I said I'm not able to work on Unlimited bc of my GPU, but something big happened. Wasif was cooking and I'm glad to announce that the new camera system is finally out of the prototype stage! Ignore how bad the game looks, it was to make sure my GPU didn't explode lol

HBM creator Kim Jung-ho reveals his lab's tHBM flipped stack publicly for the first time saying Samsung's zHBM with memory stacked on a hot GPU simply melts and is likely not the right fundamental direction "So the idea is, let's just put the HBM on top of the GPU. Then you never go outside the building, you only ride the elevator, and the speed jumps." "That's the structure Samsung is now proposing as zHBM. The z is, from the x, y, z axes we learned back in school, the vertical direction, so it means stacked in the z direction." "But unfortunately, I don't see that as the fundamental direction, because if you stack HBM on top of the GPU, the GPU gets hot and the memory melts." "So I suspect it's for very simple computation, the kind of use people call an LPU or an NPU. They showed it in passing as a fun technology, and the really important technology doesn't get shown at places like that." "So my lab researches tHBM. I believe today is the first time we're saying this publicly. We flip it, stack the HBM, and put the GPU on top of that."

PowerInfer - a high-speed inference engine for deploying LLMs locally. Just came across this super interesting project on speeding up inference. It's not MoE but it's a simple approach that exploits the high locality in LLM inference to design a GPU-CPU hybrid inference engine. Hot-activated neurons are preloaded onto the GPU for fast access, while cold-activated neurons (the majority) are computed on the CPU. This approach significantly reduces GPU memory demands and CPU-GPU data transfer. It achieves an average token generation rate of 13.20 tokens/s, with a peak of 29.08 tokens/s, across various LLMs on a single NVIDIA RTX 4090 GPU. It's on only 18% lower than that achieved by a top-tier server-grade A100 GPU. It also significantly outperforms llama.cpp by up to 11.69x while retaining model accuracy. There is a lot more innovation around inference that's coming fast. Really encouraged by the study on sparse computation to enhance the computational efficiency of LLMs. It's now possible to use PowerInfer with Llama 2 and Faclon 40B. Mistral-7B support is coming soon!
