As we have a variable number of hardware counters that can be enabled at runtime, each with a different name, we need to create a dynamic set of configuration files for Paraver. We also need to specify some options needed to properly see the timeline for HWC. For now we leave the generation of CFG to the minimum features required to cover HWC.
The ovni project is composed of a runtime library (libovni.so), which generates a fast binary trace, and post-processing tools such as the emulator ovniemu, which transform the binary trace to the PRV format, suitable to be loaded in Paraver.
The libovni.so library is licensed under MIT, while the rest of tools are GPLv3 unless otherwise stated.
For more information, read the documentation online or take a look at the
doc/ directory. You can display the documentation in HTML by running mkdocs serve from the root directory.
To build ovni you would need a C compiler, MPI and cmake version 3.20 or newer.
To compile in build/ and install into $prefix use:
$ mkdir build
$ cd build
$ cmake -DCMAKE_INSTALL_PREFIX=$prefix ..
$ make
$ make install
To run the tests you can run (from the build directory):
$ make test
See cmake(1) and cmake-env-variables(7) to see more information about the variables affecting the generation and build process.
