To find the number of nodes, first look at the Processor # / Simulation Time chart on PACE. The furthest right number on that chart is the number of processors - 1 (because of zero-indexing), so add one to get the number of processors. Divide that number by x-axis lists the highest MPI rank used, with base-0 numbering of ranks. (PE layouts often don’t fit exactly N nodes but instead fill N-1 nodes and have some number of ranks left over on the final node, leaving some cores on that node unused.) Then find MPI tasks/node in the “Experiment Details” section. The result will be the number of nodes can then be calculated as ceil((highest MPI rank + 1)/ (MPI tasks/node)).
The SYPD (simulated years per day) is listed in PACE’s “Experiment Details” section as Model Throughput.
