How do I setup the 'run_marc' command line to to run on a cluster?

1.) I would like to use 256 cores spread across 16 nodes. what combination of command line arguments will do this? I have created a host file with the names of 16 nodes using 16 cores each as follows:

Hpc-22-10:16

hpc-22-11:16

hpc-22-12:16

hpc-22-13:16

hpc-22-14:16

hpc-22-15:16

hpc-22-16:16

hpc-22-17:16

hpc-22-18:16

hpc-22-19:16

hpc-22-20:16

hpc-22-21:16

hpc-22-22:16

hpc-22-23:16

hpc-22-24:16

hpc-22-25:16

2.) Can I let slurm chose the nodes and forgo the host file?

Thanks, this is the command line that I have been trying with various combinations of the options you sent me:

run_marc -ddm 1 -nsolver 16 -nte 256 -nts 256 -v n -b n -dl n -mpi intelmpi -host host_list -iam sim -j RollingFe3D >> Two-wheel-16N-256n-DDM-1_std.log 2>&1

I keep getting the error message:

error, the number of processes specified in the host file

must be equal to the number of processes given by -nprocd/-nsolver

Is '-nsolver' the total number of cores? Or the number of hosts? Is my host_list correctly formatted?
