In the HPC application spectrum, which type of HPC application shares similarities or exhibits relatability in performance characteristics of the Serverless computing paradigm?
Any application developed within a container and deployable on HPC(Apptainer) would be relatable to the serverless computing paradigm. The performance characteristics depends on the runtime environment and the resource allocation.
Embarrassingly parallel workloads, often termed loosely coupled workloads, are the most similar to the Serverless computing paradigm in terms of performance characteristics. These workloads, where each computation does not need to communicate with other tasks, are like the event-driven, stateless nature of Serverless functions. Just as Serverless models excel in automatically scaling based on demand, embarrassingly parallel HPC tasks can be distributed across many processors without intricate inter-processor communication, which makes them very scalable and efficient, echoing the principles of Serverless computing.
