(moderation:
Hi folks,
if we not can have well optimized clients at the time, so should we have well powered optimized crunching boxes. Reduce your electricity bill by using low electricity power consumption crunching boxes.
how we can do this?
1. built by yourself your own box
what is necessary?
1.1 Hardware
- a board with integrated graphic and network support
- a SD Card 133x, used as disk
- a low power CPU with cooling tool
- a memory chip
- a power supply
- a box to build all the components in
1.2 Software, a system to run the client
- Linux, BSD, Windows etc.
- internetconnectivity over the network
-----------------------------------------------
2. to use a industrial manufactured low power consumption box like a thin client.
here you can find one (information and prices)
there you can see Xtreme PC, powerconsumption still 3,5 Watt or 5 Watt
------------------------------------------------
A lot of energy and costs can be saved if these wonderfull small machines are crunching Wu´s
-------------------------------------------------
a question for the experts, do you think these small boxes are able tu crunch, or must we develop our owns??
Your ideas are welcome

wouldn't just buying a good laptop do? i dont like them but they're suppose to be purpose built to be very power efficient. Can drop down the screen and it'll turn off. also you can use their battery like a ups battery backup.
Just a thought. Laptop would probly cost more though.
I use A64 3700+ laptop

I use A64 3700+ laptop computer. It uses ~ 75W per hour (boinc ON; screen OFF) while "big" computer (barton 2800+; Ati 9500) uses 169 W per hour (same conditions). Up to now there are no problems with it. Additional to this there is UPS (battery), and monitor included, so i think laptop is good choice (except the initial price).
RE: I use A64 3700+ laptop

I agree that a Laptop is probably the most energy efficient choice for crunching. Dual-Core Laptops with Intels T2700 or AMDs Turion X2 consume at max. 50-60 Watt under full load (screen off/no 3D-Graphics). I don't think you could best that with ten 5W thin clients running an Alchemy 400MHz. Afaik they lack the support for vectorized instructions (SSE+) and those are used a lot in typical BOINC projects.
But i did not find a lot of information about Integer/FPU Performance for the Alchemy/Geodes.

The actual AMD Geode
)
The actual AMD Geode Processors use the old Athlon Thunderbird core with SSE instructions, perhaps a bit power optimized.
The 1400 mhz version uses 25W under full load, the two smaller versions about 14W under full load.
So you can built a cheap and relative fast desktop pc with about 50W i guess under full load.
Also a good choice is the new Athlon X2 3800+ EE with 35W under full load, unfortunately it costs right now about 350€, but in about 3 weeks, the AMD dual cores get new prices up to 50% cheaper because of the new Intel ones.

If you build a desktop with

If you build a desktop with Pent M 7xx (27W max) of your choice and use the Aopen i915GMm-HFS which uses the mobile chipset, a stick or two of Ram and a HDD, IDE or SATA, then you have a PC that uses less than 70W to run BOINC/Projects.

Would you like to determine
)
Would you like to determine the power/cost efficiency of your system for einstein@home?
I can suggest this form: e = r / t / ( p * r * c + s )
e = efficieny
p = power consumption ( kW )
s = system price ( USD )
c = cost of electricity ( USD / kWh )
t = time of reference WU ( hour / WU )
r = run-time of the project ( hour )
c ~ 0,25 USD / kWh
r ~ 362 days = 8688 hours
If the reference wu takes 1 hour on a 65 wattage system that costed 200 USD:
e = 8688 / 1 / ( 0,065 * 8688 * 0,25 + 200 ) = 25,46 WU/USD
If the reference wu takes 0,5 hour on a 100 wattage system that costed 400 USD:
e = 8688 / 0,5 / ( 0,100 * 8688 * 0,25 + 400 ) = 28,15 WU/USD
So, the second system is a bit more efficient.
edit: Of course, we need a reference WU and application for the exact measuring.
RE: Would you like to

A neat idea! For the reference WU we do need the equivalent of some English King's stride .... :-)
I propose we rename the units here. 1 WU/USD = 1 'Akos' .... :-)
Cheers, Mike.
I have made this letter longer than usual because I lack the time to make it shorter ...
