CoLoRe-apptainer

Part of this project is apptainer recipe file formalizing build of CoLoRe as a containerized application.

Build

1. git clone this repo;

2. (possibly modify CoLoRe_Makefile to your liking )

3. build:

sudo apptainer build --force ./CoLoRe.sif ./container.def &> buildout.log

Tested with apptainer 1.0.3-1 on Rocky Linux 8.

Run

CoLoRe is installed into /usr/local/bin/CoLoRe inside of container, so it can be started so easy:

mpirun -np 4 CoLoRe.sif CoLoRe examples/param.cfg

contains openmpi 4.1.4 so it's reasonable to use similar version of openMPI outside of container to ensure hybrid MPI model will work properly.

other significant ingredients:

• cfitsio 4.2.0
• Healpix 3.82
• gsl 2.7.1
• fftw 3.3.10
• HDF5 from Rocky8 distribution
