My thoughts:

1) It might use one mode for CPU and one more for GPU, but I haven't thought about it beyond that.
2) One would configure the size of each work unit in terms of "1e9" or "1e12". ...

:thumbs-down:

You have no idea as to the level of effort for what you have listed.

You have contributed nearly nothing to the project, so your opinions shouldn't be considered.

SethPro, did you output the number of collisions vs inserts in the hash table from those tests? Maybe there are opportunities to sizing the hash table better.

I suggest that you start by sieving the sequence to 1e8, then continue sieving with the output file that was generated. For example:
