Timings of global ocean general circulation model OM3 on various platforms at MCS.
diagonal dashed lines indicate linear scaling
Note on Chiba City timings: "2 proc/node" means,
for example, 16 nodes were requested
for a model with 32 MPI processes. So the 2 nodes were both competing for access to the switch.
In 1 proc/node timings, # of nodes = # of MPI processes and the extra processor on each node is idle.
Below is same plot, same legend without the log scale
