Install Gaussian 16

Hello, I'm trying to install Gaussain 16 on Qlustar. I have some troubles to install it due to some right management. Indeed, Gaussian does not allow the directory on which it is installed to be accessible to others. The director should only be accessible to the owner and a group. I have created a group called gauss with Qluman in which I have added a user for a test. But the created group is not recognized in Chroot-focal. Could you tell me if you alreeady have installed G16 in Qlustar. If so could you kindly send me the procedure. Best,

Hi, In my cluster I found problems running some MPI applications (for e.g. via mpi4py) and it is related to defaults in /etc/openmpi/4.0/openmpi-mca-params.conf. When I changed btl to ^openib or to vader,selft,tcp (in case tcp nodes) - it started to work, but in this case it doesn't use UCX anymore. Regards Rolandas
