What if I don’t have a version of SLURM that supports heterogeneous jobs but I want to launch a parallel code using heterogeneous set of resources inside of a homogeneous job that was submitted with sbatch?  How do I do that?

For example, the following does not work:

#!/bin/sh --login                                                                                                                                                                                                                                 

#SBATCH --account myaccount                                                                                                                                                                                                                       
#SBATCH -p batch
