Here is a status from Mathew in an April 10th Email:

R30:
k=2538 and 2916 complete to n=140K and unreserved.
k=4372 at n=126K; continuing.
k=4897 at n=135K; continuing.

No primes to report.

Lennart,

I would be amazed if even YOU can complete this with all of your firepower without dieing of boredom first. But go ahead and impress me!

Base 25 to n=100K is one thing. Base 31 to n=100K is another thing altogether. Besides having ~7 times as many k's to test, base 31 is quite heavy weight and a larger base. It will likely take ~12-15 times more CPU time than base 25.

Lennart,

The primes abruptly ended at n=~45.5K after being fairly dense up to that point. Can you make sure you got them all in the posted file? I get a little paranoid when that happens.
