4T5T is complete:
http://www.sendspace.com/file/83jz7t 1,002,729 candidates. (iirc) Took about 26 hrs @ 2.66GHz on one C2Quad core. Most of which was NewPGen splitting the sieve into little pieces and taking it to 1G; despite reserving 485Mb. 1G to 100G only took about 3 hrs. I asked Paul Jobling some time ago if it was possible to increase the 485Mb limit but he said that Windows wouldn't let him reserve more. Nobody has mentioned this splitting. I assume I'm doing things right? Taking 5T7T on one core. (Leaving the gap at 3T4T.)

Correct 4T5T (Thanks for digging up the avatar. I did have one similar to that many moons ago. I think the fact that I keep changing it must be an identity/midlife crisis!) Last fiddled with by Flatlander on 20100531 at 14:47

I want to join this.
Due to doing something else, I'm just taking the range 8T9T. Edit: I don't want to consume too much time, so I'm releasing 8.6T~9T. Edit again: I decided again. I'm not releasing 8.6T~9T. Last fiddled with by Merfighters on 20100601 at 15:37

Elapsed time: About 12 hours.
19% of 8T to 9T sieved to 1000000007. I'm using 300Mb of memory. That's about 10% of the whole memory. Do I need to use more?

It's a low priority project after all. Running a 2T sieve took 4hrs longer than if I had done 2 x 1T sieves. NewPGen was using 400Mb of RAM even when past 1G. Must be a memory bottleneck? I expect there is a sweetspot somewhere but I'll probably stick to 1T reservations. Taking 9T10T.

http://www.sendspace.com/file/apf3ld gribozavr, do you think you can do the bookkeeping for this subproject too? I'm already storing the files on my PC, but it'll be nice to have a backup.

I can do the bookkeeping. I've downloaded all files.
