The easiest way to set up an environment with all dependencies and without side-effects on other installed software is to use a [Singularity](https://www.sylabs.io/guides/2.5/user-guide/index.html) container.
A Singularity recipe file is part of the distribution, see the PMSCO documentation for details.
On newer Linux systems (e.g. Ubuntu 18.04), Singularity is available from the package manager.
Installation in a [virtual box](https://www.virtualbox.org/) on Windows or Mac is straightforward using the [Vagrant](https://www.vagrantup.com/) system.

3.0.0 (2021-02-08)
------------------
- Run file interface replaces command line arguments:
- Specify all run-time parameters in a JSON-formatted text file.
- Override any public attribute of the project class.
- Only the name of the run file is needed on the command line.
- The command line interface is still available, some default values and the handling of directory paths have changed.
Check your code for compatibility.
- Integrated job scheduling with the Slurm resource manager:
- Declare all job arguments in the run file and have PMSCO submit the job.
- Graphics scripts for genetic chart and swarm population (experimental feature).
- Update for compatibility with recent Ubuntu (20.04), Anaconda (4.8) and Singularity (3.7).
- Drop compatibility with Python 2.7, minimum requirement is Python 3.6.

# Slurm script template for PMSCO calculations on the Ra cluster
# based on run_mpi_HPL_nodes-2.sl by V. Markushin 2016-03-01
#
# this version checks out the source code from a git repository
# to a temporary location and compiles the code.
# this is to minimize conflicts between different jobs
# but requires that each job has its own git commit.
#
# Use:
# - enter the appropriate parameters and save as a new file.
# - call the sbatch command to pass the job script.
# request a specific number of nodes and tasks.
# example:
# sbatch --nodes=2 --ntasks-per-node=24 --time=02:00:00 run_pmsco.sl
# the qpmsco script does all this for you.
#
# PMSCO arguments
# copy this template to a new file, and set the arguments
#
# PMSCO_WORK_DIR
# path to be used as working directory.
# contains the script derived from this template
# and a copy of the pmsco code in the 'pmsco' directory.
# receives output and temporary files.
#
# PMSCO_PROJECT_FILE
# python module that declares the project and starts the calculation.
# must include the file path relative to $PMSCO_WORK_DIR.
#
# PMSCO_OUT
# name of output file. should not include a path.
#
# all paths are relative to $PMSCO_WORK_DIR or (better) absolute.
#
#
# Further arguments
#
# PMSCO_JOBNAME (required)
# the job name is the base name for output files.
#
# PMSCO_WALLTIME_HR (integer, required)
# wall time limit in hours. must be integer, minimum 1.
# this value is passed to PMSCO.
# it should specify the same amount of wall time as requested from the scheduler.
