The interconnect for the compute nodes is complicated. This was taken from the inside of a hot isle.

Each pod contains two rows of hardware separated by a hot isle, where the heat generated by the computer is dumped. It's warm in there.

There were 6 pods that contained the compute nodes. These were about 20m long each.

I did a tour of raijin at NCI today. This is a part (1 of 6 pods) of the conputer that I've been using for the past 3 years.
