For compilation you need to point `FC` to the appropiate MPI\ncompiler wrapper. (Usually `export FC=mpif90`).\n\nThe solver can then be built with\n\n```\nbin/waf configure build\n```\n\nTo install it, run:\n\n```\nbin/waf install\n```\n\nRun `bin/waf --help` to see all options.\n\nWe support two methods to conveniently install a development environment\nwith the APES tools:\n\n* via the Spack manager with the packages in [apes-spack](https://github.com/apes-suite/apes-spack)\n* via a Python virtual environment as provided in [apes-pyenv](https://github.com/apes-suite/apes-pyenv)\n\nPlease see the respective READMEs on instructions on how to\nuse one of these methods.\n\nDocumentation\n-------------\n\nSee the [documentation](https://apes-suite.github.io/musubi/index.html)\nfor more details.\n\nDeveloping Musubi\n-----------------\n\nThe actual sources of musubi are found in the mus subdirectory, which is a git\nsubmodule and, thus, has a repository\n([musubi-source](https://github.com/apes-suite/musubi-source)) on its own.\nTo ease the work with this setup there is a `request` script in the `bin` subdirectory\nthat is meant to take care of dealing with the tight coupling between this repository\nand musubi-source.\n\nTesting\n-------\n\nThe unit tests are automatically run during the compilation step, unless you\ntell waf to only build musubi itself or explicitly switch off test runs.\nThe system tests are found in the `mus/examples` subdirectory and they can\nbe run with the help of pysys-test.\nTo obtain pysys-test and have it available, you can use the\n[apes-pyenv](https://github.com/apes-suite/apes-pyenv).\n\nWhile in the apes-pyenv environment install seeder and musubi as suggested\ninto the `$VIRTUAL_ENV` prefix and then run `pysys.py run` in the `mus/examples`\ndirectory (or any of its subdirectories if you want to run only the\ntests within that directory).\nYou can also list the available tests with `pysys.py ls` and see how to\nrun selected tests in its help (`pysys.py run --help`).\n\nIf you don't want to install Musubi into your `PATH`, you can also tell\npysys-test where to find it by setting the environment variable `APES_MUSUBI`\naccordingly.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fapes-suite%2Fmusubi","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fapes-suite%2Fmusubi","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fapes-suite%2Fmusubi/lists"}
