I forgot to ask thou I know Linux a bit but to be honest I'm pretty much a n00b I can make my way around terminal and such not much for GUIs ect but is there any good software from overclocking past what overdrive will let you ? In the linuxcoin distro ?

Assuming I can figure out why I'm getting rpc errors ?

Well you should be able to set any clock rate you want with AMDoverdrivectl or even with aticonfig. To be honest I haven't tried to overclock my cards under linuxcoin but theoretically it should work just the same as in windows except that you're doing it via command line.

RPC errors means your miner lost connectivity to the master bitcoin daemon. Are you mining solo, pool? This usually means there is a network connectivity issue or massive packet loss/lag.

He needs to move this operation to the Northwest Territories (Just above Alberta where he is) or as close as possible to the north pole as possible Tongue

. When it's -30 outside I don't think cooling shall be a problem. I'm being facetious here but lol someone crazy enough may do this

Here is the idea:
1. Gather all mining equipment you can get
2. Get one of these portable nuclear power station. http://www.hyperionpowergeneration.com/
3. Find a remote place in NWT at the cost of $1/acre. http://www.ehow.com/facts_6775117_homestead-act-canada.html
4. Build biosphere 3, powered by mining rigs.
5. The birth of Bitcointopia!

I know this is a bit off topic, but back to the beginning of the thread.

I am planning something similar, but on a much smaller scale

You think it would by more cost efficient to isolate the racks in a semi-sealed environment and use portable air conditioners?

By that I mean, Isolate an entire shelf with isolating plastic, available at most hardware stores. Use velcro strips to make a door, and buy portable air conditioning units from walmart.

Make an outlet to vent and keep your AirFlow CFM up.

I'm not an engineer by anymeans, if you haven't noticed yet.

Yes.

This is what I was talking about with partitioning early on.

use tubes attached to ordinary desktop/midtower cases fans to exhaust heat rather than messing/mixing it in room fighting with aerodynamic.
PVC-made isn't strong enough termally, but rest can do the trick.

in case if you prefer cool room enteriely, as usual for 19'' racks-based data-centers, keep in mind thats not so energy-efficient[even meaning air loses in tubes]

With this Your right I could fairly easily adjust the clock speed to suit the cooling needs the usual temp in Edmonton hovers around 25 in the summer an hits maybe 32 ish for 2 weeks the bonus is both sides of the room face north or south so no direct sunlight

What I was reading in the linuxcoin thread was this list

Enable overclocking ..

Code:

aticonfig --enable-od

next lets get the clocks

Code:

aticonfig --odgc --adapter=your adapter

Set them to what you want.

Code:

aticonfig --odsc 900,900 --adapter=youradapter

And commit them

Code:

aticonfig --odcc --adapter=youradapter

And set the fan speed to 70% (a good setting for most 5XXX&6XXX cards)

Code:

DISPLAY=:0.youradapter aticonfig --pplib-cmd="set fanspeed 0 70"

Here's a little bash magic to test your card temps.

Code:

while true; do
        aticonfig --adapter=0 --od-gettemperature | tail -n1 | awk '{print "Current temp: " $5}' ;
        aticonfig --adapter=0 --od-gettemperature | tail -n1 | awk '{print "Current temp: " $5}' ;
        echo $(aticonfig --odgc --adapter=0| grep GPU);
        echo $(aticonfig --odgc --adapter=1| grep GPU);
# Next lines are to check your balance if solo mining
#        BALANCE=$(bitcoind getbalance)
#        echo -ne "Bitcoin Balance: ${BALANCE}\r";
        sleep 35;
        clear
done

But I will look into adding AMDoverdrivectl. Diablo miner will be added on the next version and I will take a look at hashkill.

The MD5 hash don't match with the file i downloaded from this site today.
my hash is MD5: d50c4d3a38a1349111bac5f69b9571f1 linuxcoin-v0.1b-ati-cd.iso
while it says CD MD5: 71e5253bc5bda47003c57d71c52db869 linuxcoin-v0.1b-ati-cd.iso
My file size is 684 MB (717,387,776 bytes) on win7 32.
Who is wrong?

The md5sun for the CD version is 28bc5b424e3f33779f67fbe4fe1a9a67 I'll update now.

Don't forget the USB version is uploaded now Wink

hds are typically 5-15w where a usb stick will be less than 1w, plus you might save some more watts by not having the hdd controller in use.

He could also massively underclock each CPU and the RAM. If they're all AMD boards then turn on that cool'n'quiet junk. If he wants to be even more extreme maybe underclock the cpus so much that he can passively cool them?

lol i know that heat rises and cold stays low lol give me a bit of a break

He's right about deltaT though. It's going to be really hard to keep the room at a reasonable temperature when it's 35+ outside. One approach is to just plan for a bit of downtime when it gets too hot.

What you really need for such an operation is a centralized throttle that communicates with an agent on each node to dial the clocks back on some or part of the installation as needed instead of losing time entirely due to shutting down. Ideally, this would all be automated via feedback from temperature sensors spread around the room.

Eadem mutata resurgo

Definitely out of his depth ... but it is the best way to learn how to swim with the big boys .... good luck ... go for it!

Hint: blow the heat out up through the ceiling as much as possible and bring the new air in through the floor ... heat rises, the top stacks will be hottest ... good luck.
Q^. = m^. C_p delta T

If you can't change temp. difference you gotta move more fluid (air).

Yeah Edmonton and I was thinking about u of a researchers

not having the actual numbers what do you figure the power usage would be say of single machine running a hdd then say a thumb drive ? And I Haven't used Linux coin yet but is it fairly easy to overclock in ? ? I would need to find a cheap source of a bunch of thumb drives in order to do this

All you would need is at max 4 GB usb thumb drives which sell for like $12-20 each I guess if you buy in bulk you can get a discount maybe. Maybe something like this would be suitable:

http://www.newegg.ca/Product/Product.aspx?Item=N82E16820139291

A low RPM HD should not eat that much power but a thumb drive eats even less. We're talking watts vs milliwatts here. For example a Samsung F1 640GB is rated 0.7A @ 12V and 0.5A @ 5V - that means max 13 watts power consumption. A USB stick on the other hand will consume much much less than that - max 1 watt. SSH HDs are pretty power efficient too but they're more expensive.

Bear in mind that a USB stick will be slower typically than a HD when booting from it, but who cares cause once the OS is booted you won't be using the drive much (maybe just once in a while for system logs and other stuch miscellaneous items, even this can be disabled and optimized to not occur).

The latest version of LinuxCoin contains all the tools needed to overclock and manage ATI cards. As far as being easy it's as easy as using a command prompt. I don't think there are any GUI based utils for linux yet though.

Not to worrie about resale as I previously stated when to cost to mine out weights the benefits of mining we will be using the gpu "cluster" persay to work on some other projects and lease it out to researchers I'm sure there are alot of people that would love cheap access to that much power

Who knows lol I sure don't will play it by ear

I don't know about that.

You've got a couple of things to overcome:

1) There are already brokers for general purpose cloud-compute capacity but, nothing for GPGPU yet as far as I know.

2) Scientific computing tends toward Nvidia. Nvidia has been working on making itself a player in that area for several years while AMD is just started. People with CUDA code aren't going to have any interest in your cluster.

I expect that #1 will be resolved before long if it isn't underway already. Once that happens, #2 will disappear too.

It would be very interesting to see bitcoin miners end up as next-generation cloud providers.

As someone who has worked with clusters and Universities in the past, I'd say he actually has a lot of obstacles to overcome.

For one, this is as garage-shop as it gets. It's perfectly fine for Bitcoin mining, but it's not anywhere near the complexity required to quickly and easily load a client's software. Furthermore, the hardware outside of the GPUs is sketchy, to say the least. I doubt it has ECC memory or other dependable hardware. The overclocked GPUs are a non-starter as well, although that's easy to fix. Finally, he's going to need some serious bandwidth to his house to allow anyone to connect and move a reasonable amount of data into/out of the cluster. And if the room heats up too much and crashes a few machines in the middle of someone's compute time, it's all over.

Again, absolutely perfect for bitcoin work but a non-starter for academic purposes. Especially with Amazon EC2 providing quick and reliable instances that are billed hourly and available instantly.

You could certainly
Be right i guess it depends on the group thou we shall see at the very least I can think of a few small groups who would lease rendering time as well as a few guys doing work on md5 cracking as well as wpa stuff
