This project requires both OpenMPI and CMake.
If you are running on Mac OSX and you happen to use Homebrew, then you might want to check a custom for installing OpenMPI here.
If you open the project with a contextual IDE, for example CLion, then you will
notice that all the code related to MPI will not be "clickable". One way to resolve this
is by setting the environment variable WITH_MPI. You just need to provide whatever value to it.
Note: what I do is setting the environment variable inside the IDE, so that I do not have problems with building the project (Preferences -> Build, Execution, Deployment -> CMake -> Environment: WITH_MPI=1 ZNS_ACTIVE=1).
Please refer to the maskfile.md file that contains a section for building the project.
Several examples are provided in the examples folder. You can run most of them in the following way:
mpirun -np 4 build/mlcoalsimXmpi_ZnS examples/example00/Example1locus_1pop_mhit0_rec100.txt build/Example1locus_1pop_mhit0_rec100.out
# Without MPI:
# build/mlcoalsimX examples/example00/Example1locus_1pop_mhit0_rec100.txt build/Example1locus_1pop_mhit0_rec100.outIn the case of the example01 and example10, where a "prior" file is being used, you need to switch the directory first.
For example:
pushd examples/example10
mpirun -np 4 ../../build/mlcoalsimXmpi Example10loci.txt ../../build/Example10loci.out
