In the fast-paced world of AI/ML development, it’s crucial to have infrastructure that can keep up with the demands of ML engineers. Slow build times and inefficiencies in packaging and distributing execution files can hinder productivity and waste valuable time.
To address these challenges, our team took proactive measures to tackle slow builds and packaging inefficiencies head-on, resulting in a significant reduction in overhead and improved efficiency.
Instead of relying on outdated revisions that require repeated rebuilding and linking, we focused on minimizing rebuilds by streamlining the build graph and optimizing dependency counts. This approach significantly reduced the need for extensive rebuilding and improved overall build speed.
Another major hurdle we faced was the packaging and distribution of executable files. To overcome this challenge, we implemented an incremental approach using the Content Addressable Filesystem (CAF). By adopting a content-aware approach, CAF intelligently skips redundant uploads of files already present in the content addressable storage (CAS). This not only reduces packaging time but also minimizes fetching overhead when dealing with large executables.
To enhance the efficiency of the CAF system, we deployed a CAS daemon on the majority of our data center hosts. This daemon is responsible for maintaining local caches, organizing a peer-to-peer network with other CAS daemon instances, and optimizing content fetching. By leveraging this network, we can directly fetch content from other instances, reducing latency and storage bandwidth capacity.
Unlike traditional layer-based solutions, such as Docker’s OverlayFS, our approach prioritizes direct file access and smart affinity routing. This allows us to efficiently manage diverse dependencies across multiple executables without the complexity of layer organization. Additionally, by using Btrfs as our filesystem, we benefit from its compression capabilities and ability to write compressed storage data directly to extents.
By addressing the challenges of slow builds and inefficient executable packaging and distribution, we have empowered our ML engineers to work more efficiently and deliver cutting-edge solutions. Our focus on reducing rebuilds, optimizing dependency management, and implementing an incremental packaging solution has resulted in significant time savings and improved productivity in our AI/ML development process.
