In other words 1, 6, 7, and 8 are "luck of the draw", but the other goals are well defined.

: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:

./srsieve2 -P1e6 -n1e5 -N2e5 -s"118392*51^n+1"

Looks like the removal of memset() is where the performance boost comes from. How much of an improvement will likely be compiler specific. The OpenCL code does not use memset(), so it won't gain...
