Thanks to everyone for staying with me on this rather large computation.
If everything goes well, I can upload my range around Sept. 1st or 2nd, is this ok?

P.S.: Current relation count:

Code:
sieved Q-range:   194.2M
relations so far: 345,712,217
relations per Q:  1.780

That's OK, I'll wait for you. The current matrix is really rather too big (though at least it fits in 12GB to run, even if not to create): estimated runtime is 1500 hours on the i7, which is basically two months.

Reserving 240M-244M.

This will take me until about the end of August, which is probably a good time for me to stop.

230-240 is now finished, I'm doing 15-19.8 at the moment, which ought to be finished in time to pick up andi47's results.

So: RESERVATIONS CLOSED

I think I can collect my relations around Tuesday or Wednesday next week and upload them in the evening (GMT+2) on the same day.

Would it be worthwhile to use a dollop of HPC to solve the matrix?

If there's a dollop available, and if it would be considered a worthwhile test case (it'll probably be >20M, which might be biggest-one-yet for the parallel LA)

Unfortunately, the Teragrid account's nearly tapped out. I've got one dollup left which I want to save for 5,409-. With luck there will be a fresh supply in a month or so, but I won't know until then. I could run it using MPC (8 computers, GigE connected) though.

It seems that my run has crashed during my holiday:

206-207 is ~25% done
207-208 seems almost done.

I will upload what I have tonight or tomorrow evening.
