Notes:
- Both the cloud and the six-year old HPC system use FDR Infiniband. Is Azure superior performance a result of tuning, configuration, or age? The analysis provided by this section is that Azure interconnect is improving. Cloud offerings moving from 10 Gbps Ethernet to FDR Infiniband in the past four years makes this result visible without testing. Did we need the OSU benchmarks for verification?
- For the Poisson mini-application, the results again verify Azure has newer hardware than the authors onsite HPC system. However, what was the cause of the variance? Job/Node placement?
- The detailed description of the flying snake workflow is appreciated.
