Updates in 2026.2.1 — NsightCompute 13.3 documentation

# Updates in 2026.2.1

General

- Added support for in-process profiling workflows that dynamically load the CUDA injection library. See the new CUDA injection API header `extras/Api/nvComputeInj.h` for usage details.

- Added the `--process-id` command line option for `--mode attach` to attach to a specific process.

- Added the `--list-injection-path-64` and `--list-injection-path-32` command line options to report the paths used to load the CUDA injection library.

Resolved Issues

- Fixed an issue on QNX where Nsight Compute could fail to create temporary files or lock files in the default location.

- Fixed an issue where profiling a green-context kernel could fail after a non-green-context kernel had already been profiled in the same process.

- Fixed an issue that could cause `ncu --mode attach` to fail when range replay was followed by kernel replay in the same process.

- Fixed a crash in the CUDA injection library when an application initialized CUDA before the injection library was loaded.
