Sequoia is ranked the world's fastest supercomputer (llnl.gov)

On it's test phase it was generating hash collisions.

It's probably not the whole truth, but i suspect Sequoia is doomed to spend its operational lifespan simulating the effects of radiation on 70's era electronics. It's not bad... just kinda sad.

In case anyone missed it, here are a few more reports of the same story:
