start_server.sh referenced LOG_DIR and RESULT_ROOT without defining them,
causing an unbound-variable failure under set -u. Mirror the initialization
from run_bench.sh so the script can run standalone.
- Remove USE_FAST_BFP16_MOE=1 which caused torch parameter assignment
crash in fresh containers for w8a8_int8 mode.
- Mount model path at its host absolute path inside the container so the
bench client tokenizer can load it regardless of server --model-path.
- Default WARMUP to 0 and NUM_PROMPTS to 10 for a fast smoke test.
- Default to a single scenario; document how to run a full grid.
- Update experiment README with PLATFORM env var and override examples.
