USB Problem

We have found a bug in the FTDI drivers/CGminer used with/for the Twin bitstream. At the moment we know this is an issue in Windows7 64bit but may extend to other OS versions or even Linux. Basically we are seeing some COM ports "lost" when the host plugs and plays a new device. That can be any device e.g. memory stick. We are looking at this to determine the cause and potential fixes.

That WOULD explain a lot of problems.

DI.BFLSC.Fail
DI.BFLSC.Succeed

Butterfly Labs has recently advertised three new products in their BitForce SC line, a 3.5 gigahash/sec USB powered unit named "Jalapeño", a 40 gigahash/sec unit named "SC Single", and a 1 terahash/sec unit named "SC Mini Rig", all to be delivered in October 2012.

In the event that Butterfly Labs fails to deliver at least a sum total of twenty-five (25) units composed of all three products offered described exactly as above to customers by the end of October 31st 2012, shares of DI.BFLSC.Fail will be repurchased at combined value of DI.BFLSC.Fail and DI.BFLSC.Succeed divided by the number of DI.BFLSC.Fail shares sold minus a 1% fee. Shares of DI.BFLSC.Succeed will be repurchased at a price of 0.00 BTC.

In the event that Butterfly Labs does succeed to deliver a sum total of twenty-five (25) units composed of all three products offered described exactly as above to customers by the end of October 31st 2012, shares of DI.BFLSC.Succeed will be repurchased at a combined value of DI.BFLSC.Fail and DI.BFLSC.Succeed divided by the number of DI.BFLSC.Succeed shares sold minus a 1% fee. Shares of DI.BFLSC.Fail will be repurchased at a price of 0.00 BTC.

The final repurchase price in either outcome depends on the number of shares sold of both DI.BFLSC.Succeed and DI.BFLSC.Fail combined by October 1st. Shares will be issued at a price of one thousandth (1/1000) of one BTC.

After running 2.5.0 overnight, the reported rejects are only 0.5% now vs. 1.5% before (with the BFL singles).
That's (partly) because they're not reported. There's also about as many valid shares being silently dropped, as the shares actually being prevented.
GET THE FUCK OUT OF MY FORUM THREAD WITH YOUR FUD
Speaking the truth by calling out false claims is not FUD.
You now have the dubious honour of being the first ever person on this forum I've ignored.

Surprised it took so long.

What do you think that Kintex 7 480 would do Mh/s and Mh/W? Any insight into Artix 7s? They are supposed to slot into the Spartan 6 space once available in good volume.

I haven't tried mining on the 480s, only on V6 240s.  The reason behind this is I have a handful of unused boards that have V6s on them, while the K7 boards are all used for my real work.

I made an entry in the mining hardware comparison long ago:

The V6 240s run at 375 MH/s at about 16w.  This isn't optimized (other than to use some DSP48s), so I guess you could probably squeeze another 50-100 MH/s out of the devices with some effort.

The MH/s based on the size of the device breaks down as follows:

375MH/s / 240 = 1.5625 MH/s per "size unit"

Based on this, I would estimate the 480 could do:

480 * 1.5625 = 750 MH/s

I haven't used Xilinx's power estimator for a K7 bitcoin design, but Xilinx claims 50% less power than the V6.

So, you could assume your worst case would be 32w, best case 16w.  Somewhere in the middle will probably be your actual power.

BUT!!  You may think the Kintex 7 would be better for mining (price/performance) than a Spartan or Artix device, but you'd be wrong!

Take the Mod miner for example:

840 MH/s @ 40w in 4 x Spartan 150 devices

840 MH/s / (4 * 150) = 1.4 MH/s per "size unit"

So, the S6 is a little less efficient in terms of size/performance (partly because I used DSP48s in the V6 example to reduce logic usage, but there are other factors), but the price difference is huge.  I think the S6 LX150 is ~$100, so there's no real good reason to buy the K7 or V6.  The K7 and V6 provide more advanced functionality (high speed serial, more internal memory, more DSP slices, more pins, etc) that aren't required for bitcoin mining.  You'd end up paying for features you don't use.

Once the Artix devices come out in force, I suspect they will be similar in price/performance to the S6.  Power consumption will be somewhere between 50% less and the same as the S6.  However, they are the last devices to go into production (after the K7 and V7).

Okay, so, the forum had V7 and K7 pricing a magnitude wrong (thanks guys), so what is the cheapest way of getting SASICS? Power usage isn't an issue if we go 65 or 90nm, and BFL is going 90 or 130nm on "real" ASIC (which has yet to be proven).

I think the ideal device would be an FPGA that it just all slices, no DSP slices, no high speed serial, no large gobs of memory, etc, and on top of that offers SASIC migration.

Does any company offer that, no matter the node size?

Can we get this moved here:

https://bitcointalk.org/index.php?board=81.0

Or somewhere else besides the hardware forum?

This is not a speculation thread. DMC's ban on BFL hardware is based on what they have already done, not what they will do.
767  Other / Off-topic / Re: Diablo Mining Company will never buy Butterfly Labs hardware on: July 06, 2012, 02:38:08 AM
I still think attacking a company based on speculation is a douche move.  Wait until they fail to deliver (again) exactly what they promise and then discuss.

Otherwise there are plenty of *** speculation threads here already. 

Now amazingly the thread isnt sticky and the *** trolls enterpoint thread is also no longer sticky.

Hope that was the other mods stepping in and curbing the misuse of moderator status.

It was clearly a troll move as the speculation about *** is already available in other threads AND his shareholders were already aware of his position (he alluded to this already)
SO the only reason was to incite some form of reaction, the very definition of trolling.

Except there is no speculation here. DMC will not buy BFL hardware. I do not care if they deliver exactly what they promised, they already burned that bridge. This is purely based on their current and past actions, and has nothing to do with what they will or will not deliver.

4 times can mean the difference between 1 year to pay off, and 4 years to pay off, so still quite a gap in my opinion.

---
Or even with half price FPGA resale value, still 2 years to pay off before profit comes rolling in, assuming power consumption can match the ASIC.

BFL still refuses to quote power usage figures, and they're probably in the realm of 28nm or SASIC anyhow.
769  Other / Off-topic / Re: Diablo Mining Company will never buy Butterfly Labs hardware on: July 05, 2012, 03:32:34 PM
While performance could come close, Virtex 7 2000 can never compete with the price of BFL's ASIC, and at the end of the day, the main concern is how quickly can you pay off for the hardware.

And lets not mention power consumption. 'per chip' is an utterly meaningless metric, particularly when per GH costs and power efficiency of asics can be two orders of magnitude higher for any given process.

Anyway, there is no point trying to talk sense in to D3D.


BFL has not stated the power consumption of their SC minirigs, and their chips might be 130 or 90mm fab, while Virtex 7 is 28nm.

Even if Virtex 7s or Kintex 7s cost 3x more per mhash to what BFL claims theirs do, so what? At least the vendors of existing Spartan 6 products actually have shown to be committed to their relationship with the Bitcoin community, and these will be most likely the ones that are making Kintex/Virtex 7 products.

I have no idea how much they cost, but judging by the real cost of BFL's FPGAs in the MiniRig, and the fact that 28nm is very new so will be very expensive with no 2nd hand market, I would estimate at best you are looking at $1500 for 5GH Virtex7 vs $300 for 7GH with 2 ASIC coffee warmers.

Most likely BFL will miss the October date.

Lets say the Virtex 7 is 13x more usable slices and can be clocked 2x what Spartan 6s are stable at, thats around 7.2ghash. I think someone on the forums said they'd cost about $1000 each, so we're looking at, say, a $1200 product price. Thats only 4x more expensive per mh.

Rolling this as a SASIC could drop the price even more and also increase the stable clock speed 3-4x over Spartan 6s, or 10.8 - 14.4 ghash for, say, a $1000 product. Thats in the same ballpark as what BFL is claiming.

I don't think D3 deserves your hate as some have expressed, but I agree D3 delivering company announcements under forum mod is wrong.

Edit:
You can look at what D3 did and not be impressed, sure.  Even take it up with Theymos or whomever.  But I look at a lot of the responses here and across the forum and I just see a lot of flaming.
I've done some flaming myself and I'm trying not to engage in doing this anymore.  It's just so unproductive.

I do not maintain separate forum accounts, as that is a form of sockpuppeting. If I want to do mod actions, you will clearly see me doing mod actions. I have not used my mod powers to promote DMC.

People will use anything they can get their hands on to troll with, including attacking someone based on how much of their time they donate to a community.

As numerous people have confirmed, I can also confirm this thread was stickied. I really don't know why there is a reason to lie about that. But it doesn't make D3D more trustworthy, that's for sure...

I haven't seen it stickied, so I'm not lying about anything.

Also I don't know what they did to upset you, but if you thought you are entitled to some special treatment because you are a mining company, than that's your problem, BFL treats every customer the same regardless of their order size, and we all have to spend time waiting for responses etc..

Its not what they did to me, its what they did to everyone else. They expect us to act like normal consumers, yet they ask for 100% of the money up front. Either treat people like the investors they are, or learn how to run a business.
774  Other / Off-topic / Re: Diablo Mining Company will never buy Butterfly Labs hardware on: July 05, 2012, 01:21:16 PM
Now your lying about it being stickied in the first place?  Sheesh dude.

Now your justifying your position with more speculation about the state of the industry to justify your stance against ***'s speculation?

Lastly, you have accused others of trolling threads when it was mere discussion, now your clearly abusing your mod status and actually trolling.

Bad form.

DMC refusing to do business with BFL over poor customer service concerns is trolling? Back in my day we called that good business sense.

i dont like bfl either and will never buy that trash or support such a company however making this a sticky.. wtf what a shit forum this has become... all the staff just trolls other bitcoin operations, its a joke.

This thread is not stickied.

I am not posting this with my mod hat on, I'm posting it with my DMC hat on. Unlike some people, I can keep my duties in the Bitcoin community separate without conflict of interest.

LOL so why did you sticky it in the first place then? 

I didn't, and I don't see it stickied right now.

as a mod, will you say this thread was never stickied?

Have a screenshot? Because I haven't seen it stickied, and it is currently not sticky.

So if butterfly labs does come with an asic and the difficulty gets 100x as high, diablo mining is out of the market until another company comes with an asic?

Your shareholders will be thrilled once again.

talk about shooting yourself in the foot.   fail in the making.



BTW, abusing your moderator status to sticky posts like these and other anti BFL trolling is just shameful.

+10   this is total BS using mod privileges for own personal agenda and vendetta. 0 respect

I do not have a personal agenda or vendetta. The original Diablo Mining Company plan was to buy BFL hardware. It is BFL that talked themselves out of a sale with their unprofessional behavior, I have no control over what they do or do not do.
779  Other / Off-topic / Re: Diablo Mining Company will never buy Butterfly Labs hardware on: July 05, 2012, 12:16:26 PM

I agree, this is an abuse of mod privileges.

Im not saying that Im a fan of the way *** does business, but there is a more diplomatic way to start a discussion.

This is definitely trolling.

I have not stickied this thread.

BFL has ultimately refused to speak with their investors (ie, everyone who preordered a BFL SC rig), so it is BFL that has refused to be diplomatic about this.
