Re: Minnesota Crunchers

Just got my other e5410 and the proper heatsink. I will get it in some time this weekend. We will see how it works.


Great to hear. More points for the team. How many cores/threads total are your crunching with now?

28 cores
Dell Poweredge - 8
HP DL360 G3 - 4
2 Quads (Q6600 and AMD9150e) - 8
2 Core2Duos - 4
2 P4 3.4ghz - 2 (hyperthreaded)
2 P4 1.6ghz - 2

30 threads

I installed the processor and heatsink in the Dell Poweredge 1950 on Sunday. That went without a hitch. Fired it back up and it took off with no problems. The heat is staying in 52 to 56 C range. The heatsink was about $25 and the processor was about $25 so plus shipping the total was a little less than $60. The thermal paste was $5. The machine cost $40 so I have about $115 invested in the machine. So far it appears to get about 33,000 WCG points per day/4800 BOINC points per day. After it runs for about a week I will have a better idea of what it is averaging. So far so good. I am going to put a Kill-O-Watt meter on it and see how much juice it draws. If my electric bills get too bad it will be time to put the P4's out to pasture. It has been quite a while since I retired my last PIII, PII and K6. After a while the amount crunched is just not worth electric cost.

I used to have another of the 3.4ghz P4's but it popped the tops off of a couple of capacitors on the motherboard so it was junked out.

Cheers

Re: Minnesota Crunchers

That Dell was dirt cheap for a harpertown rig. Not the most energy efficient but better than your older rigs. Easier to maintain multicore pc's than singles or dual core pc's. After selling my Mac pro's, had two harpertown rigs, 2.5 and 2.8 ghz dual quad cores. E series harpertowns were better on the juice bill than the X series. These westmere pc's I built aren't bad. Don't have a kill-o-watt meter but hardware monitor shows 108 watts per processor. Should be good for awhile.

Re: Minnesota Crunchers

Some power thinking.....

Looking price of bonds here and Vestas (wind stuff) will yield >17%.
Another one on pic is Vattenfall (coal, nuclear), it bond yield öbaut four percent....

What is main difference of these papers that Vestas paper is real senior bond; a.k.a. even on case of bankruptcy, it's worth of something....
On another hand, Vattefall item is hybrid, so it is below all bonds, it is not actually even bond, it is more like half own money and half foreign capital...
Well, it is hybrid... Absolutely worth of nothing in case of bankruptcy and it will return interest only after bond owners has receive their interest..

Original interest of Vestas was 4,625 p.a. But because everybody is selling it like there is no tomorrow, price of it has fall to 73%.
That is why it will bring some high yield back...

On another hand Vattenfall paper, even thou it is crappy hybrid, cost 103% on aftermarkets and there fore it yield has drop to four per annum....

I think €urope will be heated with uranium and coal for some very long times to come.....
Ou, then there is this new ice age coming and all applause

At 17% there must be some substantial risk to this bond, otherwise the yield would not reflect such a market premium. Might as well buy Irish bond. Greek bond would/should be >50%. Most bondholders already took the first Greek haircut, maybe have to take another. From this side of the pond it all looks risky unless Draghi comes up with a good solution.

Good luck

Jup, local weather..
Last winter was fine example that when we have real cold weather, we do not have practically any wind at all....
Those most coldest nights where absolutely dead calm.... And yes, on those nights need for energy is most biggest one...
So on praxis, if you build wind power here, you need to build always equal amount of load following power plants...

There was this general vision that green house effect will turn Skandinavia something like Mediterranean, warm year around and people passing wind all the time..

Not yet kameraden, not yet devilish

Same here in winter. Dead calm on coldest days.
However biggest demand for electrical power hits in summer when temperature soars >90F(33C) - so many air conditioners.
Winter power demand for heat is met mostly with natural gas and fuel oil.
