This is the HPC development version of HAIL-CAESAR arrived at by porting the code at https://github.com/dvalters/hail-caesar to use LibGeoDecomp for MPI-based multi-node parallelism.
To build the HPC version of HAIL-CAESAR you will need the following installed:
- g++ (more recent than version 6)
- an MPI library (e.g. MPICH, OpenMPI, ...)
- Boost
- LibGeoDecomp
cp ./include/make/make.inc_template ./make.inc(or copy a readymade make.inc for the system you are building on if it already exists in /include/make/, e.g. make.inc_ARCHER)- Modify
make.incto specify the locations of Boost, LibGeoDecomp, and the MPI library, and the MPI compiler wrapper command to compile C++ code (e.g. mpic++) - Run
make
You will be able to run the resulting executable ./bin/HAIL-CAESAR.mpi with the relevant parallel application launcher command (mpirun, mpiexec, aprun, etc.) as follows, e.g. to run on 32 nodes = 768 cores on ARCHER:
aprun -n 768 HAIL-CAESAR.mpi params_filename
The params file is used as in the original version of HAIL-CAESAR as described as http://hail-caesar.readthedocs.io/en/latest/
