Here are the high-level steps:
1. Login and go to reach the gpu selection page
2. Click on the Load Provising profile and then select the multion-profile and load it
3. After the profile has been correctly selected and loaded continue
4. If an on-demand A100 GPU is available with 80GB RAM, then reserve it
5. If reservation is successful, then enable ssh access and return public ip to access the machine
