-Gaussian can only do shared memory parallel calculations, i.e. using processors within the same node, so %%--nodes%% should always be 1. Furthermore, it is important to start only one Gaussian process/task, which itself will make use of the available cores. This is achieved by settings %%--ntasks%% to 1, while %%--cpus-per-task%% can vary: srun will then launch only one Gaussian process.+Gaussian can only do shared memory parallel calculations, i.e. using processors within the same node, so ''%%--nodes%%'' should always be 1.
