Login to SciComp GPUs

The following is how to use one of the ML scicomp machines that has 4 Titan RTX GPU cards installed.
A couple of notes:
Setting up the software environment seems to be more easily done using conda. Will Phelps sent me the magic commands. It seems at least part of the environment is maintained when the srun command is called. At least I was still in the same working directory and python3 was pointing to the venv. However, the virtual environment was not completely set up so I had to source the activate script again I was able to pip install from the sciml190X node whereas it failed to do it from the regular ifarm node due to missing SSL modules.
