Limitations
Gaussian 16 is available at NHR@ZIB.
"Linda parallelism", Cluster/network parallel execution of Gaussian, is not supported at any of our systems. Only "shared-memory multiprocessor parallel execution" is supported, therefore no Gaussian job can use more than a single compute node.
Description
Gaussian 16 is the latest in the Gaussian series of programs. It provides state-of-the-art capabilities for electronic structure modeling.

Specifying GPUs & Control CPUs for a Gaussian Job
The GPUs to use for a calculation and their controlling CPUs are specified with the %GPUCPU Link 0 command. This command takes one parameter:
%GPUCPU=gpu-list=control-cpus
Restart calculations from checkpoint files
opt=restart
Restart molecular geometry optimization from checkpoint file. All existing information; basis sets, wavefunction and molecular structures during the geometry optimization can be read from the checkpoint file.
