    It is not the case that The PRAM model is not considered a reasonable model of computation

    ?Set your confidence on the premises below to see your aggregate.

    Reasons For

    2 perspectives
    Reason for 1 of 2
    ?
    • 1.Reasonableness of a computational model is relative to the physical substrate being modeled, not an absolute classification.
      ?

      Think about whether this reason is strong or weak

    • 2.Massively parallel architectures like GPUs and neural hardware increasingly approximate PRAM's concurrent memory access assumptions.
      ?

      Think about whether this reason is strong or weak

    • 3.Van Emde Boas's machine class taxonomy was developed before modern parallel computing architectures made PRAM-like behavior physically realizable.
      ?

      Think about whether this reason is strong or weak

    Reason for 2 of 2
    ?
    • 1.The ability to simulate non-deterministic Turing machines efficiently is a feature, not a disqualification, if one's criterion for reasonableness is computational power relative to physical resources.
      ?

      Think about whether this reason is strong or weak

    • 2.Conflating 'unreasonable for sequential complexity theory' with 'unreasonable as a model of computation' commits a category error about the purpose of machine models.
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    1 perspective
    Reason against
    ?
    • 1.A PRAM machine can simulate a non-deterministic Turing machine by recruiting sufficiently many processors to carry out all computation paths in parallel
      ?

      Think about whether this reason is strong or weak

    • 2.This places the PRAM in van Emde Boas's second machine class, which is not considered a reasonable model of computation
      ?

      Think about whether this reason is strong or weak
