SUMMA telemetry: ring time histogram by message size
...
Per log2-size bucket: messages, GB, seconds inside SendToRecvFrom, GB/s,
% of ring time. Decomposes the 2 GB/s/rank average (probe: 11-20 GB/s
at 8 MB) into latency-bound small messages vs slow large ones vs wait.

Dense allgather: stage/scatter x by global-site order, not rank-major block
...
DENSE_DEVICE_SUM=4 assumed each rank's rows of x were the contiguous
[me*nrows,...) block; x and the slab columns are in global-site order
(hX[myGsite*nbasis+b]), the contiguous block is the rank-major index.
Coincide on one rank only -> Frontier VERIFY 0.9965. Stage via myGsite,
scatter through the inverse of BuildRankMajorMap. 4-rank laptop VERIFY
7.38e-07, identical to the allreduce path.
