+# Run MLPerf tests
+
+NOTE: currently only tried with mixtral;
+and only tried with offline benchmark
+
+# How to run
+
+### 1. Install 
+
+```
+./install.sh
+```
+
+### 2. Start server
+
+```
+./start_server.sh
+```
+
+### 3. Warm up the server
+
+```
+python warmup.py
+```
+
+### 4. Run the benchmark, now it runs offline mode
+
+```
