 High-Performance Serverless for HPC and Clouds

(In 37th IEEE International Parallel & Distributed Processing Symposium (IPDPS), PhD Forum, May 2023)


Function-as-a-Service (FaaS) computing brought a fundamental shift in resource management. It allowed for new and better solutions to the problem of low resource utilization, an issue that has been known for decades in data centers. The problem persists as the frequently changing resource availability cannot be addressed entirely with the techniques employed so far, such as persistent cloud allocations and batch jobs. The elastic fine-grained tasking and largely unconstrained scheduling of FaaS create new opportunities. Still, modern serverless platforms struggle to achieve the high performance needed for the most demanding and latency-critical workloads. Furthermore, many applications cannot be “FaaSified” without non-negligible loss in performance, and the short and stateless functions must be easy to program, debug, and optimize. By solving the fundamental performance challenges of FaaS, we can build a fast and efficient programming model that brings innovative cloud techniques into HPC data centers, allowing users to benefit from pay-as-you-go billing and helping operators to decrease running costs and their environmental impact. My PhD research attempts to bridge the gap between high-performance programming and modern FaaS computing frameworks. I have been working on tailored solutions for different levels of the FaaS computing stack: from computing and network devices to high-level optimizations and efficient system designs.
