Unexpectedly, this question turns out to be intimately related to the complexity of deterministic context-free language (DCFL) recognition.
The recognition problem for a deterministic context-free language L is to decide, given a word x, whether x [element of] L.
Parallel random access machines with owned global memory and deterministic context-free language recognition.
Third, using the same basic machinery, we show that the recognition problem for deterministic context-free languages can be solved quickly on a deterministic auxiliary pushdown automaton having random access to its input tape, a log n space work tape, and pushdown store of small maximum height.
Recall that LOGDCFL is the class of languages log space reducible to deterministic context-free languages.
It was shown in Section 3 that generalized CROW-PRAMs satisfying G1-G6 can be simulated by deterministic auxiliary PDAs with log n space and polynomial time, and thus that languages recognized by such machines are in Sudborough's class LOGDCFL of languages log space reducible to deterministic context-free languages.
