Benchmarking UM Version4.5 on different Architectures
Preamble
- Cluster/Parallel file systems are often a bottleneck.
- If the model is not filesystem-bound, it is often (MPI massage) latency-bound.
- Only the master process writes output, this can lead to load-balance issues, which hinder scaling.
