Mare Nostrum is indeed "our sea", and it was the name given to the Mediterranean sea during the roman and bizantine periods. Therefore, it was considered appropriate for a supercomputer in a city on the Mediterranean coast.
Reminds me much of the "computing center" at my alma mater: http://www.rpi.edu/about/campustour/vcc/index.html
It had formerly been a large stone chapel when that part of the campus was part of an adjacent seminary. It always struck me a bit ironic that the geeks at a technical school now "pay worship" to the computer housed therein.
Programmer to omniscient supercomputer: Is there a God?
Supercomputer: There is now.
