    144144  The Sieve of Eratosthenes using parallel writes into a sieve structure represented as an array of `Bool`s. 
    145145
    146   '''Todo''': We currently don't have a proper parallel implementation of this benchmark, as we are missing a parallel version of default backpermute.  The problem is that we need to make the representation of parallel arrays of `Bool` dependent on whether the hardware supports atomic writes of bytes. Investigate whether any of the architectures relevant for DPH actually do have trouble with atomic writes of bytes (aka `Word8`).
     146  '''Todo''': We currently don't have a proper parallel implementation of this benchmark, as we are missing a parallel version of default backpermute.  This needs a parallel update operation, but we currently can't guarantee atomic updates of compound types such as tuples.
