The Machine vs Samaritan is closer than we think.

Kind of depressing that it's only going to be used for our mistakes. Maybe Sierra will say the best solution will be to just get rid of the bombs. I would think the medical field could make better use of it.

They look like a network of gigantic Playstations...

Right on, it's running Linux!

Those are just the doors on the rack enclosures. Inside each rack it's quite boring to look at.

Performance wise- it would kill a network (of any size) of PS4 nodes. A huge gain is from the Power9 CPUs connected to the V100 GPUs via NVlink (way faster than PCIe).

But each Sierra node also costs considerably more (Nvidia V100 alone are $10,000 each, a single node has 4), and the network (dual EDR 100Gbps Infiniband with 480x 36-port TOR switches and 9x 648-port director switches) would cost millions of dollars itself.

For those curious, lots more technical details here:
