Running benchmarks that require code#

Some of the benchmarks require plugins like custom material models, boundary conditions, or postprocessors. To not pollute ASPECT with all these purpose-built plugins, they are kept separate from the more generic plugins in the normal source tree. Instead, the benchmarks have all the necessary code in .cc files in the benchmark directories. Those are then compiled into a shared library that will be used by ASPECT if it is referenced in a .prm file. Let’s take the SolCx benchmark as an example (see Section The SolCx Stokes benchmark). The directory contains:

  • – the code file containing a material model “SolCxMaterial” and a postprocessor “SolCxPostprocessor”,

  • solcx.prm – the parameter file referencing these plugins,

  • CMakeLists.txt – a cmake configuration that allows you to compile

To run this benchmark you need to follow the general outline of steps discussed in How to write a plugin. For the current case, this amounts to the following:

  1. Move into the directory of that particular benchmark:

    $ cd benchmarks/solcx
  2. Set up the project:

    $ cmake .

    By default, cmake will look for the ASPECT binary and other information in a number of directories relative to the current one. If it is unable to pick up where ASPECT was built and installed, you can specify this directory explicitly this using -D Aspect\_DIR=$<$...$>$ as an additional flag to cmake, where $<$...$>$ is the path to the build directory.

  3. Build the library:

    $ make

    This will generate the file

Finally, you can run ASPECT with solcx.prm:

 $ ../../aspect solcx.prm

where again you may have to use the appropriate path to get to the ASPECT executable. You will need to run ASPECT from the current directory because solcx.prm refers to the plugin as ./, i.e., in the current directory.
