The nOS-V events are modified in two ways: 1) to create a parallel task the new VTC event must be used and 2) all task events for both normal (VTc) and parallel (VTC) tasks require an extra argument in the payload to indicate the body id. As a consequence, the nOS-V model version is now increased to 2.0.0. Additionally, all the channel PRV flags are set to PRV_SKIPDUPNULL, so duplicates are only emitted if they are not null. It solves the problem when a task switches to another task with the same body id. A new Paraver configuration is added for the body id.
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.
