Welcome to CRUS firejuggler. If you have any questions about sieving or testing, let us know.

Can I ask what range you plan to sieve and test and how many cores can you dedicate to it? 7 k's at n=120K for such a high base is a lot of work. One modern quad-core running all 4 cores 24x7 should be enough but progress will still be slow.
