APL on large vector machines

Howdy, folks!

I was a bit surprised that no mention was made of the APL*STAR programming language on the Control Data STAR supercomputer (evolved into the ETA 10 super). A description of the language can be found here: APL STAR reference manual

It's interesting from a historical standpoint because the original STAR-100 super was a wide-bandwidth pipelined vector processor. Scalar operations were essentially performed as vectors of length 1. What killed performance was the startup time for a vector operation. Something that Gene Amdahl said on the subject eludes my memory at the time. Later versions of the hardware included a dedicated scalar unit. ^[1]

I created a Keyman keyboard for APL. [1][2] 92.9.35.203 (talk) 09:38, 17 July 2022 (UTC)[reply]

Snap?

Is Snap! really based on APL? Is it vandalism? 89.67.244.199 (talk) 13:21, 31 December 2023 (UTC)[reply]
