This 50core card is designed to do double precision calculations, consumer GPUs only do single precision.

High-end AMD consumer GPUs (69xx, 77xx, 78xx, 79xx) do support double precision.
Most Nvidia ones support it too (albeit artificially throttled).

Well, just nvidia always sucks hard.
Yeah, that's why their Tesla stuff shows up in pretty much all of the new supercomputer builds these days, right?  Roll Eyes

1443  Economy / Computer hardware / [closed] [WTS] So... I herd u liek BFL Singles - Rev 2 (non-heatpipe) available! on: June 20, 2012, 03:57:53 PM
SOLD

So I have this 2nd gen (non-heatpipe) single that has kind of been thru the war. I'll probably be keeping it (nope, selling it now), but if you guys are feeling rich I might am selling it. This one has been featured in a video and immortalized in crappy pictures of mine. It runs the 872 firmware reliably, but the higher ones don't seem to work without throttling. Imgur album here: http://imgur.com/a/cALGV

Tell me what it is worth to you!

Notes - has been taken apart a few times, and might be dusty from running for several months. Stock bottom fan broke when I set it down on some stuff while it was running, so I have replaced it with a crappy smaller fan that I had laying around. Pics:









I have been assured by BFL that as long as the device works, the fan issue will not hurt the trade value.

EDIT: Selling now. SOLD

id say the singles are worth 600, there is no premium now that everyones waiting in line for asic's & trade-ins...

and that 600 is 50% down on your asic upgrade.

so they are still worth their $600 bfl price, as they will honer that price they were sold.


Get em, and Wait in line for trade-ins next tax season though... it's my guess they favor the pre-orders and new customer's first, let that die down then do trade-ins...

Yes but anybody that is paying $600 for a single right now will be able to recuperate the costs before reward halving and ASIC coming ( Dec 2012 ) ?
No, but they will be able to get a $600 credit towards new equipment.

Yeah but $600 CREDIT for equipment ( that can come in 4-6 weeks Cheesy ) is not = $300 cash right now in my bank account.

Just like MtGox USD does not equal USD already in my bank or how cellphone credit does not equal currency in Africa.
That's your personal valuation of such a credit, and you are entitled to it.

AND THERE WE HAVE IT.....

You can trade a regular Single in towards the purchase of an SC Single, but you can't trade in two regular singles to get an SC Single.  I know people would rather do that, but it's not a working business model.  
Sweet, are you going to stop raising cain now? The past few days, half of the posts have been you bitching endlessly.

Tell me that I was right and I will run away and die a happy man.....

So far they aren't soliciting pre-orders [for SC equipment] anyway. Perhaps they will wait until they are ready to ship, this time. We shall see, I suppose.

Another win by BFL.

They could have completely screwed their customers and not offer any trade in so value of single with ASIC coming = maybe $10.

Now this basically ensures the value of the single is at least $300 which is excellent for some who are half way through paying off the unit and want to sell right now and stop gambling.
Is your calculator broken?

Again, IM not sure I see the point. Say I plunged a few million dollar on making that maskset, and Im struggling to recover my investment. Why would I let you run a few wafers? Even if I did, and charged you an arm and a leg for it, since you have to run them through the same fab as me, its really the same thing as selling you the processed wafers, and assuming you dont want to duplicate the costs for testing, packaging etc, you would really just be buying my chips.
Well even if it were possible, I'm fairly sure no sources will be released until the company is profitable, so that is a moot point.

I think the idea is to produce something for a profit, and once the production is running with a working device, they will then open-source as much of the product as they are allowed to. Some parts may not be allowed to be open-sourced because of foundry NDAs, but anyone would be able to take the stuff that is open source and give it to the foundry to create a device.

And whats the benefit of doing so, to anyone? The RTL we already have (well, more or less), anything beyond that like the synthesis and  place and route will be covered by NDAs, but even if they werent, it would only be useful at one specific fab using one particular process and its usefulness would be limited to someone nearly doubling the NRE by ordering pretty much the exact same maskset. If this chip arrives 6+ months after BFL, I would be surprised if they could recover the costs of one design and maskset, anyone trying to do the same another 6 months later is completely out of his mind. "Opensourcing" stuff like PCB design is almost equally pointless, the PCB will be utterly tied to the asic.

I think many people here would like to see BFLs bitstream and have people improve on it, and therefore think opensource hardware is somehow good, but that only works for FPGAs. Once this asic has taped out, any brilliant idea anyone might have to improve on it will be useless.

Anyway, I dont think this is the biggest hurdle this project has ahead of it. Im my mind, Ive started making a list of "bitcoin tops and flops of 2012", and I fear this project will feature in the latter list, along with Diablo's $1M Mining corporation, Vladimirs "huge" asic mining company and a few other pies in the sky. But I guess we'll see.

It seems to me that doing this would allow others with different PCB designs to get on the ASIC bandwagon for cheap. Let's say for instance that OpenASIC plans to make a consumer-friendly low power device with one or 2 chips. Since they have already designed an ASIC, all I as a PCB designer would have to do is create a design around them to be whatever I wanted, such as a 1 or 2U rackmount unit with 42 processors, for instance. Is there some reason that this won't work?

I think what you may be saying is that each user that spins up will have to create a new mask; if this is true that would be a bit of a waste. However I don't know any reason that they couldn't just re-use an old mask, unless there is some limitation that I do not know about.

Just got a response from Jody.  You have to put up 50% of the cost, the other 50% can be trade in.

I understand how you are confused. This whole thing has not been explained in detail. If it were a straight trade of old equipment for new our business would fold in a week. Here's how it works: if you buy $599 worth of BFL product--say 4 Jalapenos, you are eligible to send in a Single to exchange for 4 more Jalapenos. You must buy something to be eligible to trade something of equal value. And you don't have to send in your old equipment when you pay for the new--you send it in when you are notified that your ASIC equipment is ready to ship. Does this make sense to you?

Jody

I don't know if I believe this post since on the BFL press release it says very clearly ---

"Because our first and second generation equipment is expected to be outpaced very quickly by the new hardware, customers who have purchased earlier generation products will be able to trade them in at 100% of their value toward the purchase of SC-generation hardware."

It would be nice if BFL would come here and explain this in their own words rather than hear it from a 3rd party.

The quote from "Jody" is their own words, she is an employee of BFL.

So word on the street is the Xeon Phi is supposed to be directed to compete with the nVidia Tesla presence in the supercomputer market? Seems like a bit of a war will roll out: x86 vs CUDA vs OpenCl? Did AMD stop developing Firestream cards?
I'm pretty sure each x86 core is significantly more capable than any of nVidia's CUDA cores. But because of this, they are larger and there are fewer of them. It depends on how complex your stuff is whether you use this or whether you use CUDA.
1459  Bitcoin / Hardware / Re: [ANN] OpenBitASIC : The Open Source Bitcoin ASIC Initiative on: June 20, 2012, 01:31:05 PM
We are negotiating with 3 different ASIC's fabs at this moment, we expect to have the figures for a full ASIC implementation anytime soon. Right after that, we will come with an adapted plan to finance it. 

I personally see BFL's announce strategy only designed to make actual competition the highest possible damage.
So I will love to beat them both in price and time to market. 

Its time for a reality check; if you have yet to select a fab and process, you cant even have taped out yet, much less have a maskset. What you do have is an FPGA design that might be ported to a process, but that still needs to be done, the analog part probably still needs to be done, the design must be tested, characterized and validated for that process,  then you have to order the maskset, wait for it to be produced, then you have to order the wafers, wait for wafer processing, you have to get the chips cut, packaged and tested, design and order and test the PCBs, do Q&A, software, etc.

IOW, you are as far as BFL would have been 9 (or more likely 12) months ago. How in the world do you expect to beat them to market?

No offense Gusti, but by your own admission you have no experience in the semi conductor industry and you seem to be treating this as the purchase of a car or something, asking around quotes and expecting to place an order and be done with it. Even for a structured ASIC it wouldnt be quite that simple, but the development process of a custom asic is a lot more complicated than that, and I would feel a lot more confident in the outcome of your project if someone was involved that has any experience designing, producing and bringing to market a digital design of any kind. I know thats not you, nor Jason, so I would urge you to bring someone on board who has that experience. Now you could outsource all of that (prepare for a shock when you get the quote and tentative planning) but then you wouldnt be negotiating with fabs like you say you are.

As for the business aspect of this; you may call it opensource or community driven, but what does that even mean if you are simply a company that will fund the NRE to develop and sell another asic? I fail to see the big difference with BFL.  If the community aspect of this will be the funding, good luck raising the $1+M you would need to come to market with a product that will start a price war with BFL (and potentially others) who will already have recovered their NRE and because of their early sales, will have pushed up difficulty to a point where your asics will be worth only a fraction of what they could be worth today.

I may be missing something, and I hope Im wrong, but I just dont see how this is going to fly.

I think the idea is to produce something for a profit, and once the production is running with a working device, they will then open-source as much of the product as they are allowed to. Some parts may not be allowed to be open-sourced because of foundry NDAs, but anyone would be able to take the stuff that is open source and give it to the foundry to create a device.
