[slurm-users] Not able to allocate all 24 ntasks-per-node; slurm.conf appears correct

Thanks Jeffrey and Chris.
This does not work:
srun -N 1 -n 24 --pty bash -i
But this works:
srun -N 1 -n 24 --ntasks-per-core=2 --pty bash -i
So one has to be explicit about ntasks-per-core on the command line or in the sbatch file, even though ThreadsPerCore is in slurm.conf.
