- Add experiments/dsv4_p800_long_context_matrix for 64k/128k/256k context grid on DeepSeek-V4-Flash-INT8 with Kunlun P800. - Change bench_client_docker.sh to use --concurrency instead of --max-concurrency to match the user's long-context benchmark script. - Add SGLANG_HEALTH_CHECK_TIMEOUT override to server_docker.sh for slow long-context server startups. - Tune dsv4_p800_256k_4k_probe with lower max-running-requests and mem-fraction-static to avoid OOM on P800.
DSV4 P800 256k-Input / 4k-Output Probe
Kunlun P800 XPU + SGLang + DeepSeek-V4-Flash-INT8 long-context OOM probe.
What it does
Sends 4 prompts with 262144 input tokens and requests 4096 output tokens at concurrency=2, then checks whether the server completes the scenario without OOM or context-length errors.
Quick Start
Against an already-running server (recommended on shared P800 machines)
PLATFORM=kunlun_p800 \
SKIP_MANAGE_SERVER=1 \
PORT=30000 \
bash experiments/dsv4_p800_256k_4k_probe/run_bench.sh
Standalone (starts its own Docker container)
PLATFORM=kunlun_p800 \
bash experiments/dsv4_p800_256k_4k_probe/run_bench.sh
This will start a fresh sglang-dsv4-flash container with the baseline
w8a8_int8 launch args (no EAGLE speculative decoding), plus
--context-length 270000 --max-running-requests 4, and tear it down on exit.
To use the tuned config with EAGLE speculative decoding instead:
SERVER_MODE=w8a8_int8 PLATFORM=kunlun_p800 \
bash experiments/dsv4_p800_256k_4k_probe/run_bench.sh
Configuration
Edit config.env or override via environment variables:
# Use a different port or model path
PORT=30001 \
MODEL_PATH=/data1/models/DeepSeek-V4-Flash-INT8 \
PLATFORM=kunlun_p800 \
bash experiments/dsv4_p800_256k_4k_probe/run_bench.sh
