It will be added soon.
Question: is it "total" memory bandwidth? Or "per-core" bandwidth?
How should it be calculated for some common processors? I'm afraid practitioners will put the right answer but most others folks will mess it up.
There is also the question of accelerators: do we report two bandwidth values?
from hpcg.
Can we use the STREAMS metric for the whole system? I think this is what most people would want to know. The HPCG bandwidth metric is the observed total system bandwidth for the CG phase. I use an idealized model such that each array is assumed to be read/written once per operation. For example, the read/write counts for SpMV (y = Ax) assumes that x is read once (8n bytes, where n is the global problem dimension) and y is written once (also 8n bytes).
