Modal: Taming GPU Price Volatility with Linear Programming

2025-05-09

Modal tackles the volatile GPU market by employing a linear programming (LP) algorithm. Their resource solver system analyzes real-time demand, pricing, and availability to dynamically adjust GPU instance counts, ensuring optimal pricing and satisfying customer needs. Even with constraints like various GPU types, CPU, RAM, and regional limitations, the system allocates resources within seconds, leveraging price discrepancies to save millions annually. This guarantees fast scaling while employing heuristics and Google's robust GLOP solver for reliability and stability. Customers enjoy seamless scalability without the complexities of cloud resource management.

DoppelBot: Your CEO, Now an LLM

2025-02-04

Modal has created DoppelBot, a Slack bot that can replace your CEO (sort of!). It fine-tunes an OpenLLaMa model on your team's Slack messages to mimic your CEO's communication style. Built on Modal's serverless platform, the entire process—scraping, fine-tuning, inference, and Slack event handling—is streamlined and efficient. The open-source code allows for easy deployment and customization within your workspace. Using LoRA for efficient fine-tuning and supporting multiple workspaces, DoppelBot offers a novel approach to team collaboration and productivity enhancement. The article details its functionality and deployment steps.

GPU Glossary: A Comprehensive Guide to GPU Architecture

2025-01-14

The Modal team has created a comprehensive GPU glossary to address the fragmented nature of GPU documentation. This interactive online dictionary connects concepts across different levels of the stack, from CUDA architecture to nvcc compiler flags. Users can navigate via hyperlinks or read linearly. The glossary covers device hardware (CUDA architecture, Streaming Multiprocessors, etc.), device software (CUDA programming model, PTX, etc.), and host software (CUDA C++, NVIDIA drivers, etc.), providing developers with a comprehensive and easily understandable resource for GPU knowledge.
