Reinforcement learning at scale runs thousands of isolated rollout sandboxes in parallel, and packing more of them onto each host lowers your cost per training step. This post shows how to tune Firecracker microVM density on Amazon EC2 metal, and introduces labsweep, a harness for mapping your own latency and density curve.

In healthcare, generative AI is transforming how medical professionals analyze data, summarize clinical notes, and generate insights to improve patient outcomes. From automating medical documentation to assisting in diagnostic reasoning, large language models (LLMs) have the potential to augment clinical workflows and accelerate research. However, these innovations also introduce significant privacy, security, and intellectual property challenges.

This post builds on our workshop “Build multi-party crypto wallets with AWS Nitro Enclaves” which demonstrates a Shamir Secret Sharing (SSS) application. The SSS app securely splits cryptographic private keys into multiple shards, requiring a threshold number to reconstruct the original key, ideal for Nitro Enclaves as it prevents any single party from accessing the complete key while maintaining operational functionality. AWS Nitro Enclaves provide isolated environments that keep critical operations such as decryption and cryptographic key management secure from both from root user and external threats.

Amazon EC2 offers AMD-based instances built on multiple generations of AMD EPYC processors. This post focuses on optimization strategies for the 3rd and 4th generation families, which provide enhanced capabilities for compute and memory-intensive workloads.
