* Makefile improvementsJoshua Bakita2025-03-20
| | | | | | | | | | | | | - Add an "all" build target - Fix build if libcuda.so is not on linker search path - Do not assume that nvcc is available on $PATH - Allow specifying CFLAGS and LDFLAGS when running make - Allow passing non-standard CUDA build locations to make Suggested usage if CUDA is installed in a non-standard location, say, /playpen/jbakita/CUDA/cuda-archive/cuda-12.2: make CUDA=/playpen/jbakita/CUDA/cuda-archive/cuda-12.2
* Bugfix stream-mask override, support old CUDA, and start Hopper supportJoshua Bakita2024-12-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | Use a different callback to intercept the TMD/QMD later in the launch pipeline. Major improvements: - Fix bug with next mask not overriding stream mask on CUDA 11.0+ - Add CUDA 6.5-10.2 support for next- and global-granularity partitioning masks on x86_64 and aarch64 Jetson - Remove libdl dependency - Partially support TMD/QMD Version 4 (Hopper) Minor improvements: - Check for sufficient CUDA version before before attempting to apply a next-granularity partitioning mask - Only check for sufficient CUDA version on the first call to `libsmctrl_set_next_mask()` or `libsmctrl_set_global_mask()`, rather than checking every time (lowers overheads) - Check that TMD version is sufficient before modifying it - Improve documentation Issues: - Partitioning mask bits have a different meaning in TMD/QMD Version 4 and require floorsweeping and remapping information to properly construct. This information will be forthcoming in future releases of libsmctrl and nvdebug.
* Support CUDA 12.2, 12.5, and 12.6 on Jetson aarch64Joshua Bakita2024-12-19
| | | | Also test and note that stream masking on CUDA 6.5 seems impossible.
* Support stream masking on CUDA 12.3 (x86) and 12.5 (x86)Joshua Bakita2024-11-26

* Support stream masking on CUDA 12.4 (x86) and 12.6 (x86, aarch64)Joshua Bakita2024-11-26
| | | | Credit to Nordine Feddal for testing CUDA 12.4 on 550.544.14.
* Add build and use instructions to the READMEJoshua Bakita2024-02-19
| | | | | Also allow building with an alternate version of g++ for backwards compatibility.
* Add test that higher-granularity masks override lower-granularity onesJoshua Bakita2024-02-14
| | | | | | | | | | | Stream-level masks should always override globally-set masks. Next-kernel masks should always override both stream-level masks and globally-set masks. Tests reveal an issue with the next-kernel mask not overriding the stream mask on CUDA 11.0+. CUDA appears to apply the per-stream mask to the QMD/TMD after `launchCallback()` is triggered, making it impossible to override as currently implemented.
* Add a README and tests for stream masking and next maskingJoshua Bakita2023-11-29
Also rewrite the global masking test to be much more thorough.
