43000G-46000G Finished
Found 6957614 factors

46T-50T in progress (reserved)

Note: After the 46T-50T range is complete i will be stopping manual work for a while.
Max No need to reserve any work if it is just for me.

GPU's will be busy on the upcoming PG challenge and will probably stay on the grid for some time after that.

Okay, sounds like a plan. I'll hold off on reserving anything more until we get any more requests for reservations here. (@Gary: how you coming on getting that GPU machine's OS reloaded? :wink:)

Is a double-precision-capable GPU necessary to help in this drive?

[QUOTE=nuggetprime;247366]Is a double-precision-capable GPU necessary to help in this drive?[/QUOTE]

No. I've run the tpsieve-cuda client on a GeForce 210 (its compute capability is 1.2, and 1.3 is required for double-precision things like CUDALucas and genefercuda) and it worked (as fast as ~2.8 CPU cores while using nearly no CPU but slowing the display to a crawl, but low performance should be expected from such a cheap card). I'm not sure of the minimum compute capability rating needed to run tpsieve, perhaps it's 1.1 like mfaktc.

Reserving 50000-50010 G for the start. Yes,I know that's tiny,but I just have a GT 240 to help out and it's not one of the fastest GPUs out there:smile:
I hope it's OK that I reserve such a small range!

Oh...I probably should have posted something to this effect earlier, but 50000G-50010G is NOT the next available range. That would have been done a while back in the PST forum. What I would need to do is reserve another large block over there and list it as available here, and then you could take a range from that.

I hadn't bothered to keep an active reservation for this thread since there was very little activity here; for Gary's GPU that we managed to get online a couple weeks ago, I've been feeding it with work reserved directly in the PST forum.

If you'd like me to grab another block for this thread, I can do that--just let me know. Alternatively, you can reserve a range directly in the PST forum at [url]http://primesearchteam.com/showthread.php?t=25[/url].

Sorry for the confusion.

Max :smile:
