Executing the taskyield in a loop causes the runtime to maximize the probablily that we end up running the task again before we have the chance to emit the PPe event, so making the emulator panic as this breaks the current OpenMP task model.
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.
