[...]In that case and optimistically assuming that the missing interface logic can be added to makomks code, the current table looks like this:[...]

I'm not quite sure, so eventually excuse me for wasting time. You filled in "109.29 MHash/s" although "Fmax=109.29MHz" was reported. (MHz instead of MHash/s). Or are they the same when fully unrolled?

Btw congrats makomk, your result sounds great Wink

Please stop talking off-topic about bruteforcing bitstreams with gpus (that means, stop talking about this here). this thread is about the hardware part.

I'm sure that we'll find someone who could get us those bitstreams, if special software is needed. Please focus on the hardware part.
3  Bitcoin / Bitcoin Discussion / Re: bitcoin client should be renamed bitcoin wallet ? on: June 27, 2011, 06:48:50 PM
no because i expect the client to be able to handle multiple wallets. for example a "load" function which pops up a file-search-dialog followed by a password prompt (or maybe usb dongle or stuff).

i would call it "bitcoin banking application" or stuff...

"bitcoin wallet" is misleading and confusing, as a thing named "bitcoin wallet" already exists, naimly the wallet file itself.

sry for pushing this up if the thread was just a cheap attempt to troll.

Exactly, the ARM will have to boot the FPGAs, unless they have a configuration flash on the board itself.

Okay. Then i request an autoupdater to a server where "bootcode" for every daughterboard is stored, so that i just have to insert my wallet address (you know.. by pushing little buttons on the backplane. it would have a little display for this, combined with btc counter!) and keep paying the electricity bills. Smiley

Thanks again.

[... Long text ending with: ]Would CPU hashing still be more efficient in a massively parallel cloud of clients, than some kind of virtual appliance, emulating the essential features of a GPU? Interesting possibilities methinks. Anyhow thanks for the info. You can learn so much, just by asking stupid questions to clever people. Grin

What kind of shit did you just smoked man? Cheesy

You may want to stop thinking about emulating gpus and start thinking about... a futuristic society formed by talking trees and then use your energy to write a book about it.

My intention was to use this ARM CPU as the host, and communicate via ethernet from there. No need for a sheeva plug.

I as a noob have a questin here: As different Daugtherboards/FPGAs should be supported, would this ARM CPU program these fpgas? Or how do you do this, as nobody except the backplane knows which types of daughterboards are connected?

Additionally I want to say that I really enjoy this thread here. Thanks for everybody involved. I guess I will personally switch in read-only mode for now, as I have only slightest experience with such electronics.

Maybe look at this mining problem another way.
The FPGAs don't really get such high hash rates and cost too much.

The point is the low energy consumption. GPUs will not be used in some months because of their high wattage and then we need to be there with our low-energy-boards. Although I'm a bit pessimistic right now because somebody could have non-free very easily pluggable asic system right then and straight away fill a server farm with thousands of these boards.

Would "our" modular system capable of taking asic boards if available? there was a thread right there about someone "founding asics for the community" but i guess this was a troll or got selfish or busy or whatever http://forum.bitcoin.org/index.php?topic=14910.80

The future of bitcoin is asic i believe. asic or death Wink

Nice idea. I would be interested in buying such a thing. Every week earlier this is ready is money, so we need to speed up i guess.

I'm no expert though.. Do you have some pieces in mind? I would guess that maybe some "cheap" sha256 chips exist, although hard to find?

Edit: Searched a bit for modular fpga units and found this at ebay Cheesy http://cgi.ebay.com/XILINX-XCV1000-4BG560C-FPGA-Virtex-LOT-60-PIECES-/170507774436 Too bad I don't know the fpga-scene at all...

Financial gain that simple really and he only made $1000.

$1000 in btc I heared and they were worth 0.01$ back then. so he made 100k btc which is quite more than $1000.

So what's going on? Can I already buy some board? Wink
11  Bitcoin / Bitcoin Discussion / Re: Anyone know what happened to knightmb and his 371,000 BTC? on: June 18, 2011, 04:09:22 PM
haha knightmb,

you were very lucky and still are. know what? i would be very happy about 10k btc.
and because you really are not happier with 371k then with 361k (you know it!), you should really send 10k btc to me at 1AWqSp8zh1BPYaN96UE8KxLzKg7Kd9SoTn Smiley
12  Bitcoin / Hardware / Re: Will fund ASIC board for mining community. Need Hardware devs. on: June 12, 2011, 08:54:28 PM
I just want to say that I find this whole ASIC-Thing very interesting and a great engagement. If I'd be sure that I could get those babies running, I would throw say a thousand bucks in the ring.

As for high initial costs we could open a website which tracks the spendings from each member to the project and then calculate the board price as "sum of expenses / boards delivered".
Then at first only a small amount could be produced (for say 1500$ per unit). Later when a second (equally large) order needs to be placed in china, resulting in a price of 500$ because no more design etc has to be done, the overall price would be 1000$ bucks, which every board would cost then. then the members who payed 1500$ initially would have like 500$ cash-back or discount on further boards. they would practically a board for free.
As I stated above both orders were equally large, so you notice that this calculation makes no sense. but you get the idea, hmm? Wink
13  Other / Beginners & Help / Re: Newbie restrictions (Please discuss forum policy here.) on: June 12, 2011, 12:06:57 PM
As far as I read, the restrictions were only introduced because of heavy trolling. And my experience tells me that a troll can find even better satisfaction in screwing existing discussions than in establishing new ones.
Don't think this is such a good idea... But the mods/admins will have more experience with them trolls Wink
I don't see how these restrictions (5 posts + 8 hours online) will prevent massive trolling. It is quite easy to make a bot which will keep newly registered profile online to take required nubmer of hours and post few sentences in this section.
I didn't said that those will prevent trolling. In fact a troll wouldn't need a bot at all cause he would be sitting bored in front of his pc anyway.

Now that i read about the decrease from 50 to 5 posts, my interest in discussing this topic in here is suddenly practically zero... hehe
14  Other / Beginners & Help / Re: My bitcoins are lost on: June 12, 2011, 11:17:23 AM
maybe your local transaction data is not up to date (it should show like 130266 blocks in your bitcoin program).

or maybe the transaction is just not processed. in your situation i would just wait a few minutes, most likely everything will work out correctly.

I, as a newcomer, agree 100% Cheesy

But to be serious: If we restarted now, then we would  be (part of) the early adopters and we have the same problem, right?

I can offer myself as an example.  I have been reading about bitcoins for the last couple of days and have been giving some thought to buying some.  I also wanted to offer some feedback to a forum member who has started a bitcoin giveaway site designed to help people like me 'get on the ladder' so to speak.

This policy absolutely drives me away as a matter of principle.  This forum appears to be THE source for BTC related information and you are shutting people like me out who may occasionally want to contribute or offer feedback.  I have no intention of making 50 posts just to 'earn' the right to play with the big boys.  

Do you want bitcoins to gain wider acceptance or do you want it to be an exclusive club that can be entered into only by those 'in the know'?  I get the impression of the latter at the moment.

I agree about the two leading paragraphs. But the exclusive club thing is meant to be exclusive in the sense of "no trolls". I think you as a "non-troll" will be whitelisted in minutes.

Maybe the following mechanism would be better: Anybody can post, but messages can be flagged as "bullshit" by "seniors" and when a member got a say 40% bullshit-rate it gets to this playground here. But then again someone would need to implement this.

Edit/PS:
Of course this bulletin board thing here is so 1990 at all... Cheesy
It should be no problem to collect some 1k btc (The early miners got them in buckets, don't they?) and pass them over to a nice company which makes a nice page out of this, with automatic trade-reputation or even middle-man-system and stuff.
18  Other / Beginners & Help / Re: Did we just go down? on: June 12, 2011, 10:33:17 AM
who is going down?

bitcoin is decentralized and as far as i know there's no thing as "we are going down".
19  Other / Beginners & Help / Re: The Future of Bitcoins as a legitimate currency on: June 12, 2011, 10:31:51 AM
I agree, if btc continues to grow the way it is now, we will see a "noob friendly" system in that time.  BTC is going to be known as a historical game changer for online retailers in the future.

Amazon will never accept bitcoin. See paypal declared bitcoin as illegal already. (OK paypal is expected to be deeply routed to the government, but most of the global players are)

With bitcoin, who exactly do you prosecute? How exactly are going to prosecute someone living in africa or russia who owns and operates an exchange?

I'm not a lawyer but there are laws to control the flow of "values" (think about taxes or import restrictions).
Bitcoin is anonymous (to the state) and though the law cannot be "fulfilled". So the use of the currency will be forbidden for everyone.
