SimpleLLM: Minimal LLM Inference Engine
Read Full Article: SimpleLLM: Minimal LLM Inference Engine
SimpleLLM is a lightweight language model inference engine designed to maximize GPU utilization through an asynchronous processing loop that batches requests for optimal throughput. The engine demonstrates impressive performance, achieving 135 tokens per second with a batch size of 1 and over 4,000 tokens per second with a batch size of 64. Currently, it supports only the OpenAI/gpt-oss-120b model on a single NVIDIA H100 GPU. This matters because it provides an efficient and scalable solution for deploying large language models, potentially reducing costs and increasing accessibility for developers.

NVIDIA’s BlueField-4 Boosts AI Inference Storage
Read Full Article: NVIDIA’s BlueField-4 Boosts AI Inference Storage
AI-native organizations are increasingly challenged by the scaling demands of agentic AI workflows, which require vast context windows and models with trillions of parameters. These demands necessitate efficient Key-Value (KV) cache storage to avoid the costly recomputation of context, which traditional memory hierarchies struggle to support. NVIDIA's Rubin platform, powered by the BlueField-4 processor, introduces an Inference Context Memory Storage (ICMS) platform that optimizes KV cache storage by bridging the gap between high-speed GPU memory and scalable shared storage. This platform enhances performance and power efficiency, allowing AI systems to handle larger context windows and improve throughput, ultimately reducing costs and maximizing the utility of AI infrastructure. This matters because it addresses the critical need for scalable and efficient AI infrastructure as AI models become more complex and resource-intensive.

Multi-GPU Breakthrough with ik_llama.cpp
Read Full Article: Multi-GPU Breakthrough with ik_llama.cpp
The ik_llama.cpp project has made a significant advancement in local LLM inference for multi-GPU setups, achieving a 3x to 4x performance improvement. This breakthrough comes from a new execution mode called split mode graph, which allows for the simultaneous and maximum utilization of multiple GPUs. Previously, using multiple GPUs either pooled VRAM or offered limited performance scaling, but this new method enables more efficient use of resources. This development is particularly important as it allows for leveraging multiple low-cost GPUs instead of relying on expensive high-end enterprise cards, making it more accessible for homelabs, server rooms, or cloud environments.

Boosting GPU Utilization with WoolyAI’s Software Stack
Read Full Article: Boosting GPU Utilization with WoolyAI’s Software Stack
Traditional GPU job orchestration often leads to underutilization due to the one-job-per-GPU approach, which leaves GPU resources idle when not fully saturated. WoolyAI's software stack addresses this by allowing multiple jobs to run concurrently on a single GPU with deterministic performance, dynamically managing the GPU's streaming multiprocessors (SMs) to ensure full utilization. This approach not only maximizes GPU efficiency but also supports running machine learning jobs on CPU-only infrastructure by executing kernels remotely on a shared GPU pool. Additionally, it allows existing CUDA PyTorch jobs to run seamlessly on AMD hardware without modifications. This matters because it significantly increases GPU utilization and efficiency, potentially reducing costs and improving performance in computational tasks.
