This brings a bit of a tear to the old eye. I worked on Mira's predecessor and a bit on the acquisition of Mira itself (literally rooms and rooms of Gantt charts, floor to ceiling, wall to wall), and it's very cool to see it get put in. A fine job was done by the Argonne staff to get this thing purchased and accepted.

My only correction is:

With this particular computer, that's not strictly true. These are special low-memory A2 PPC chips that, to the best of my knowledge, aren't in much else.
