This has been solved.

First attempted was a full 8-character upper/lower/numeric brute force 
which took over 6 days and failed.

Second attempt was lower-case with control characters, and succeeded in 
around 40 minutes.

There's a control character in it ;)

Because of the outpouring of negativity about these disclosures, I am 
reluctant to post the actual password without the user's consent, since 
he's still alive. If anyone knows Bill, and can contact him, please ask 
for permission.

This was done on three nodes of a Dell HPC cluster, each node containing 
two Tesla V100 nVidia GPU cards, for a total of 30720 CUDA cores.
