How long did this simulation take to fully render

This simulation was run by Illinois physics graduate students who were members of my group, and then visualized by them. The simulation was run on a supercomputer and took about 2000 "node-hours" (1 node hour occupies 1 of the multi-CPU machine that is linked together to make the supercomputer for 1 hour) to run on what was then one of the fastest machines in the world. Now these simulations take far less time, and are run on GPUs.
