Cocke-Kasami-Younger, Valiant, Earley, Graham-Harrison-Ruzzo.

Even simpler than the serial LL(k) and LR(k).

I haven't tried to vectorise/parallelise them, nor do I know if anybody
else has--after all we all know Parallel Compilers/Parsers are
impossible.

Perhaps you have never heard of FTN200's Extended Basic Block Optimiser
(Kenner's EBBO)? 205 rather than Cray or Convex so I guess it doesn't count.
