I thought that I was more likely to be stepping on other peoples' toes if I took the shortest sequences, so took a batch of more nondescript ones from the middle.

The machine cost me £4344, and I was able to get about £800 back from selling other compute nodes that it had displaced. It uses about 500 watts; a lot more power-efficient than an equivalently-CPUed pile of Sandy Bridge machines, and with this machine I get to allocate 64GB to a single process if I want.

I'm having a hard time convincing myself to spend ~$500 on another system for home. (I could replace an old single core with a nice hex core for that price....)

Pleasure, I'm afraid.

Taking 61656 and 39690.

853740 is currently at i466, size 120, [COLOR="Blue"]2²[/COLOR]. Hence it is currently driverless, I will keep this one reserved.

fivemack 2011-07-10 20:49

Abandoning 631650 (i412, 2^3*3*5); haven't done anything serious on the C126.

bchaffin 2011-07-11 01:12

I'll take 664470.

Batalov 2011-07-11 01:18

Will move 307944 out.

smh 2011-07-11 11:06

477108 is done for this project.

I'll keep it a little longer and see where it goes.

bchaffin 2011-07-13 16:39

I'll take 111624 too.

unconnected 2011-07-13 16:55

Taking 47934 78288 53466
