Hacker News with Generative AI: GPU

The Asus Ascent GX10 a Nvidia GB10 Mini PC with 128GB of Memory and 200GbE (servethehome.com)
NVIDIA’s platform, previously codenamed Project DIGITS, is a hit at GTC 2025. Apparently, big customers are asking if they can get a DGX Spark thrown in with large GPU purchases. The reason is simple, this is a mini PC form factor that packs an Arm CPU and a Blackwell GPU that are co-packaged, a 128GB LPDDR5x shared memory, multiple ports of USB4, and even a ConnectX-7 NIC for 200GbE clustering.

DeepSeek open source DeepEP – library for MoE training and Inference (github.com/deepseek-ai)
DeepEP is a communication library tailored for Mixture-of-Experts (MoE) and expert parallelism (EP). It provides high-throughput and low-latency all-to-all GPU kernels, which are also as known as MoE dispatch and combine. The library also supports low-precision operations, including FP8.

GPU Glossary (modal.com)
We wrote this glossary to solve a problem we ran into working with GPUs here at Modal : the documentation is fragmented, making it difficult to connect concepts at different levels of the stack, like Streaming Multiprocessor Architecture , Compute Capability , and nvcc compiler flags .
