The E10k was only a 64-core machine on a tight backplane compared to

Sequent and SGI did with multi-drawer interconnects to drive
excellence in NUMA.
When I started work at Cambridge in 2002 our central supercomputer was being replaced with
a cluster of Sun Fire E15K machines with a fancy interconnect - it topped out at position
199 on the top500 list https://www.top500.org/list/2003/06/?page=2 with a 300 core
configuration. It looks like they never managed to get the whole thing working as a single
cluster since the other two thirds of the installation had positions 200 and 201! (The
Nov. 2002 top500 list has it in 6 x 144 core shards.) Here’s a news item about it:

True. There is also at least one unencumbered
strategy such as epoch
based reclamation which was known about around that time [2]

The big benchmarks in this lovely thesis were run on one of the E15K supercomputer boxes
