Updated WRF benchmarks (Q1 2022)

One of the great things about working with public CSPs is that they continue bringing the latest hardware options from different manufacturers to the benefit of all of us. We continue evaluating the performance of several HPC apps with the latest hardware so that our customers can make informed decisions. Our updated round of WRF benchmarks include measurements with Intel Ice Lake and AMD EPYC3 (Milan) processors from AWS and Azure.
The figure reflects overall WRF performance on computing and high-performance-computing instances from AWS and Azure.

The above WRF performance has been evaluated from an assemble of several test cases ranging from a single domain (1,500 x 1,500 points) to forecast with several nested domains. The overall performance, which is essentially inversely proportional to wall times, is weighted from these test cases and normalized with a maximum score of 100% for an instance being the best performer for every test case.

The measurements reflect performance on the following instances:
