I've suspended k=301 and 323 for a few weeks and am pouring most of my resources at port 300. k=303 and 309 are still going.

I'm quite disgusted at this effort at the moment. 30,000+ tests with no primes on 4 k's.

Even for n>600K, that is far longer than it should be.

The last time I complained on a long primeless effort at CRUS, a few primes finally came shortly thereafter so this is my official complaint to make the primes come out. lol
