+# NVTX Profiling Guide
+
+## Overview
+
+NVTX (NVIDIA Tools Extension) provides performance markers visible in Nsight
Systems. This project uses zero-cost macros that compile to no-ops when the
`observability` feature is disabled.
+
+## Build with NVTX
+
+Default builds exclude NVTX for zero overhead. Enable profiling with:
+
+```bash
+cd /mahout/qdp

Review Comment:
Don't know why, but I actually not compile successfully. Could you help me
out?
```sh
$ cargo build -p qdp-core --example nvtx_profile --features observability
--release
