We at Johnny’s Software Lab LLC are experts in performance. If performance is in any way concern in your software project, feel free to contact us. There was a rumor I read somewhere related to training AI models, something along the lines “whether we compile our code in debug mode or release mode, it doesn’t matter, because our models are huge, all of our code is memory bound”. I wanted to investigate if this is true for the cases that are interesting to me so I wrote a few small kernels to i

TL;DR We have some very fast AI-generated kernels in pure CUDA-C without using libraries and DSLs such as CUTLASS and Triton. They are performing close to or in some cases even beating the standard expert-optimized production kernels shipped in PyTorch. Some of our highlighted results: Matmul (FP32): 101.3% performance of FP32 torch.matmul; problem size: 4096x4096 square matrices performance of FP32 torch.matmul; problem size: 4096x4096 square matrices Conv2D: 179.9% performance of FP32 torch

This is going to be a long post, but I hope you get value out of it. This wasn’t an easy topic to tackle but it was definitely worthwhile! Hopefully, you leave with a decent understanding of how memory ordering works and how to use atomics in conjunction with memory ordering to build a lock-free queue in C++. Note: If you want to actually compile the code and run it, make sure to do so with the TSan flag enabled for the CLang compiler. TSan is a reliable way of detecting data races in your cod

In a nutshell: A modder recently upgraded an 11-year-old Nvidia GTX 970 from 4GB to 8GB VRAM to see if the additional memory could improve its performance. The modified card not only outpaced the original model but also outperformed a stock GTX 1060 with 6GB of VRAM in some benchmarks. Brazilian hardware modder Paulo Gomes modified an Asus Strix GTX 970 for his experiment. To boost VRAM, he removed the original 512MB, 7 Gbps GDDR5 modules and replaced them with 1GB, 8 Gbps chips. He also added

According to a recent report from DigiTimes, Chinese memory maker ChangXin Memory Technologies (CXMT) is on track to abandon DDR4 production for PCs and servers by mid-2026 – seemingly under order of the Chinese Communist Party. The move is a bit surprising considering the company just started mass producing DDR4 modules late last year. The strategy appeared ef

There are some applications that benefit from running LLMs really, really fast. This low-latency regime encompasses applications like chatbots and human-in-the-loop workflows, where users care a lot about seeing responses come back immediately.

Not everyone is able to write funky fused operators to make ML models run faster on GPUs using clever quantisation tricks. However lots of developers work with algorithms that feel like they should be able to leverage the thousands of cores in a GPU to run faster than using the dozens of cores on a server CPU.
