Until now, emulation models were always being registered via probe(), which causes the emulator to initialize all the channels. To reduce the overhead, the channels were not connected or registered in the bay until the first event of that model was received. This delayed connect was causing issues in muxes where the newly connected model required refreshing the touched channels. Which in turn was causing unexpected PRV events. By determining which models we need to enable, we can remove the delayed connect mechanism and just enable those models at initialization time, and connect the channels.
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.
