runner/servers: add --pp for both engines (xserv --pp N; llama.cpp -sm layer over N GPUs). New drivers: pp_final.sh (sequential latency + per-GPU VRAM + byte-exact correctness), pp_diag.sh (single x2 vs pp4 x2 determinism control), pp_quality_full.sh / pp_llama_47.sh (AIME+GSM8K matrix, xserv on 0-3 || llama on 4-7), summarize_pp/summarize_fullq, pp_time.py latency probe.

# Run the PP=1/2/4 sweep with xserv and llama.cpp CONCURRENTLY on disjoint GPU
|
|
# groups: xserv (--pp) on GPUs 0..N-1, llama.cpp (-sm layer) on GPUs 4..4+N-1.
|
|
# The 8x5090 box is grouped 0-3 / 4-7 (PHB intra-group), so each engine's P2P
|
|
# stays intra-group and the two engines never contend for a GPU.
|
|
#
|
|
# xserv splits layers across N GPUs and hands off hidden states via NCCL P2P;
|
|
# llama.cpp's default `-sm layer` does the analogous layer-wise split.
|
|
#
|
|
# Run from the repo root on the GPU host. Produces bench-out/pp{1,2,4}-{xserv,llama}.
