I was sort of surprised to find that the top500 list on their website only goes back to 1993. I was hoping to find some ancient 70’s version of the list where his ridiculous Pi cluster could sneak on. Oh well, might as well take a look… I’ll pull from the sub-lists of

https://www.top500.org/lists/top500/

They give the top 10 immediately.

First list (June 1993):

     placement  name            RPEAK (GFlop/s)
     1          CM-5/1024       131.00
     10         Y-MP C916/16256 15.24

     1          SR2201/1024     307.20  
     10         SX-4/32         64.00

     1          ASCI Red        1,830.40
     10         T3E             326.40

Apologies for any transcription errors.

Actually, pretty good showing for such a silly cluster. I think I’ve been primed by stuff like “your watch has more compute power than the Apollo guidance computer” or whatever to expect this sort of thing to go way, way back, instead of just to the 90’s.
