Rebirther,
I fear to speculate how difficult it would be to set up a sieving effort via boinc, but ... there's been a TON of computing power added just within the last 3 days to this project .... but,
I think it a worthy endeavor to start eliminating bases outright... and hence my question as to what is being done on the bases with 5k's or less in regards to sieving since N is getting larger and tests are taking longer??
If BOINC sieving isn't feasible at this time, I am familiar with SRsieve and can do some manual sieving; I have a couple of i5 cores to donate...

I have no clue what Neo just said... but as his teammate, I'm sure it was good ;) I can pitch in a couple of cores to help out...

You could help with manual sieving at mersenne.

Prime Grid has a nice sieving app. Do you think they would
give you a copy of it?

Rebirther,
Ok, I can/will do that. Are there any bases in particular that we are working on here at SRbase that you feel need to be taken significantly deeper?
Again, I was thinking of those bases where five or less K's remain (i.e., where N is above 500K)

Yes, all with 3k or less could be interesting.

There's a challenge on Primegrid fast approaching. My cores will be dedicated to crunching for that challenge...
After that challenge though, I will take two bases significantly deeper... I will P/M Rebirther for his recommendation on which two bases he thinks we have a good chance of knocking 'out of the park'.
It's a good way to bring a TOP 5000 prime to the 'surface' :)

Our sieving apps are open source and freely available to anyone who wants to use them. Actually, all of our apps are open source.
There's a lot of 'glue', however, that needs to be built to manage the sieve data on the server. That's the hard part.
