821  Economy / Securities / Re: Forward-looking statement for upcoming July 1st dividend on: June 28, 2012, 04:25:18 AM
Our second dividend and first full month dividend is quickly approaching.

Estimated total dividends: 75.52 to 83.00 BTC
Estimated per share dividend: 0.028495 to 0.031827 BTC


Well, this is fun. BTCMC is not going to honor the .125 BTC/mo dividend in the contract. This estimate is now wrong, and is probably going to be around 27 to 35 BTC total dividend, or less than half. Thanks Yochdog.

Dude, you have to pay attention to the thread.

We had 1,000 shares issued paying a dividend of .15 per share.  We did a 10 for 1 split, thus we now pay .015 per share.  We are still going to pay out the same 150 BTC as before. 

This was very clearly stated in the thread we have for the company. 

Yes, and all of DMC's holdings of BTCMC are apparently post-split.

Well, not all news is bad today.

Diablo Mining Company has now passed 11 Ghash, and we're also 57 shares short of 4000 shares sold.

Yes, that one, where he is no longer going to honor the contract he agreed to on GLBSE.

had to read that 3 times to catch the .125 in the contract vs the intended .0125. thats a pretty big difference.

Yup. I guess over the next month I'm going to dump the BTCMC holdings I have.

It is unclear whether Xeon Phi can dual-issue LRBni (512-bit) instructions (and has enough execution units to execute 2 per cycle), or can only do it for x86-64 (32/64-bit) instructions. I assumed the former, hence my 280 Mhash/s estimate. If not, performance would be 560 Mhash/s as 2112 pointed out.
I agree that unclear is the operative word. I have feeling that Intel's James Reinders is heavily under the influence of the marketing department. There's some talk that the current board is a coprocessor, yet the ISA manual clearly shows the unit booting in the 16-bit segmented real mode.

Intel is either doing artificial market segmentation or something didn't work out in the memory controller/quickpath/chipset interface portion of the design.

I also wonder if the references to the "original Pentium" are similar to the branding exercise that happened with the announcement of the orignal Atoms. The Atoms had completely redesigned microarchitecture called Bonnell, but with various features disabled. Yet the marketing described them as "reissue of the classic Pentium" while pretty much the only thing that they had in common was lack of deep speculation and in-order execution.

Well, the real problem is, they want to be able to boot existing x86 code on it. Not merely run, but boot.

I'm thinking they're this: Atom-like cores, dual issue, in order execution, no x87 FPU, and a 512 bit SIMD unit that does both integer and fp, 32?kb of L1, and a small amount of L2.

Now, given that sounds shitty, but if I can run normal threads on those instead of lockstep thread clusters and the SIMD units support booleans (512 of them at a time) or chars (64 at a time), this could actually end up with surprisingly fast mining.

827  Other / CPU/GPU Bitcoin mining hardware / Re: Xeon Phi on: June 27, 2012, 05:41:20 PM
Given all these assumptions, a Xeon Phi card should mine at roughly 280 Mhash/s, or about as fast as a low end HD 7850. Not impressive.
I wonder how this number is going to change once we include the information that the basic core resembles Pentium which was dual pipeline and that now the cores are 4 way hyperthreaded.

From the Pentium days I remember straightforward Fortran & C code easily retiring more than 1 instruction per clock: 1.3-1.6 with nothing more than "-Ofast".

I would double your number to 560 Mhash/s. This should be a safe assumption that the pipeline utilization could get close to 100%.

I thought hyperthreading only have like a 25% performance boost tops?

Superscalar is not hyperthreading.

For the FPGA or the ASIC?

FPGA. I don't believe BFL will be shipping ASIC this year, if ever.
829  Economy / Securities / Re: [GLBSE] BFLS.RIG - BFL Hardware mining & Sales on: June 26, 2012, 08:40:48 PM
Yep, as soon as the hardware is delivered.  Same deal as BFLS, whatever is earned by the machines gets paid out as dividends.


Has BFL given a delivery date for yours?

They all basically produce 0.6 MH/s per Mhz engine clock speed.

Nice, so at 1250 MHz you should get 750 MHash/s ?

That seems about right. On DiabloMiner on my 7970 at 1125 I get 675.

The bigger question now is : how many reference 7970s ( or the new better binned GHz editions ) can reach 1250 MHz without overvolt ?

I dont get this binned GHZ edition shit. Mines a ref design factory overclocked to 1010mhz, and I got it like 4 months ago. It happy cranks away at 1125mhz at stock volts.

You don't get marketing ?

Cheesy

GHz edition is supposed to make it "cool" to the noob gamers and convince them that 7970 is comparable to GTX 580.

When it clearly isn't ...

Of course it isnt. NVidia totally botched the 580, they'll never catch up to AMD at this rate.

834  Bitcoin / Hardware / Re: FPGA development board "Lancelot" - official discussion thread. on: June 26, 2012, 09:35:43 AM
BFL is supposed to be taking preorders today. ASICs are bringing huge changes to Bitcoin, ones that could even effect non-miners. I believe all of these changes will be for the best in the long run though. Now we can just hope that the openasic project turns something out in the next few months!

Yes, and they took preorders in Bitcoin primarily, and some estimates now put the amount of Bitcoin trying to be cashed out by their processor at $300,000 worth, which may be difficult for them to process in the near future. Since these preorders cannot be reversed and the estimated cost for an ASIC run is $3-5 million for all three devices and the time for development could be as long as 6 months or more, there is a very high likelihood we may see BFL not have enough money to do ASIC development for several months and the ASIC itself for several more months. In all, it could easily be a year or more before ASIC drops.

I think FPGA devices still have some play, but obviously these are all things to consider when ordering or implementing new designs. I know I would still buy Lancelots if they were developed, though I'd probably still prefer a quad-miner of some sort.

we (my team and some other core people) consider BFL have not spend any money on ASIC development yet. BFL's business flow is: announce dreamlike specs -> taking pre-orders -> find people to development -> if succeed, release and shipment. if fail, run. BFL sell products at super low price because their customer take all risks.
so now BFL is just collecting money for their ASIC project and avoid current delivery pressure (means they are running out cheap FPGAs).
if this business model succeeded, i will classified this as a shame of human intelligence.

and let me explain what is the "now in final stage development" mean. in ASIC design flow, this means RTL design is nearly finish. as a SOC or some other complex ASIC, RTL design and testing will take most of the development time. but mining ASIC is not a RTL complex design, it is a high computing density chip. most of the work is physical design, packaging and thermal design. RTL is less than 10% of the entire work.

What does the developer say? Do you have a solution for the bitstream yet? I'd love to buy one or two Lancelots rather sooner than later. Do you think it's risky to invest in FPGAs now? I'm not so worried about the energy efficiency but to achieve a high hash rate in order to still be able to compete at all with ASICs next year. I'm assuming the time for ROI is more than one year, or isn't it?

nearly finish.
the price will let the ROI in ~6 months.

I agree with this assessment.

Giga is smart as hell : just like BFL is forcing the current FPGA buyers to spend even more on BFL so is giga forcing the current bond holders to upgrade for a fee so he gets even more $$$

Well played, gigavps !

Hats off to you.

I still believe pirate = gigavps = BFL = government but that is conspiracy theory so disregard it Wink !

Liking the power board. When it is available will it be possible to just add those to our shipments if we request/pay for them?



Actuallly I was looking at the post before. Yes that's very much the idea that you can do more or less what you want with the wiring. It's always difficult to get PCIE leads to wire up nicely in a rig always the wrong length and it's hard to split them nicely. Hopefully this board will be of use here. I imagine it will get used for other non-Cairnsmore uses as well. ATX PSU are hard to beat in efficiency terms and high power at a reasonable cost.

The plan is that this is an initial version and we will follow up with one supporting Ethernet as well. That enhanced one won't be done for 2-3 months yet. Depends on how busy we are,

Currently your board only limits 24pin and PCI-e connectors, i want to know why? Every PSU still has 2-3 molex 4-pin wires (i'm counting only wires because other connectors share the same wire are useless). Why not maximizing the available wires of a PSU? to save few bucks cents on the connector?


Most powersupplies can be maxed out on PCIe and +12v EPS pins. I don't know why you're throwing a hissy fit over obsolete and bulky 4-pin molex connectors. The better question is why aren't the 8-pin EPS connectors being utilized. 

Its not hissy fit when there are other enterprise PSU that we can use. The 4-pin molex is still very popular outside of PC.


Most enterprise PSUs that I have seen are 12vdc bulk powersupplies that then feed an in-chassis 5vdc and 3.3vdc power supply that steps down 12vdc. Then again your idea of enterprise and mine may differ. To me enterprise = rack mount gear. There might be a market for an adapter that could accept a rack-mount PSU and output a metric shit ton of PCIe 6-pin connectors. Problem with that though is you have to deal with 40mm fans..

To be fair, thats how all high efficiency PSUs work now. AC->DC 12v, DC->DC 12v->whatever for everything else.

In principal but typically in a rack-mount server that I've seen/worked with there are redundant 12vdc PSUs feeding a single power distribution block. Principal is the same, the hardware layout is different.

Well, HW layout is still actually the same, its just that the DC->DC VRMs are in the PSU housing instead of the modules (which also may not be outputting 12v, some I've seen output 24v for high wattage situations). Its kinda shitty when you realize that although your 12v is redundant, your 5v and 3.3v isn't.
838  Economy / Services / Re: Gigamining / Teramining on: June 25, 2012, 01:53:39 AM
Well giga how about it can you man up on that one or are you just going to screw these people proving me right?

It has NEVER been my intention to screw anyone over. According to the Poll I put up, 84% of the respondents thus far would like to turn gigamining into teramining. This is a huge majority and I am thrilled that gigaminers want to come with me on this ride.

Therefore, gigamining will turn into teramining when ASIC arrives and it will include both a free upgrade path and a paid upgrade path.

So even though the upgrade path is free you can't resist the chance to grab even more, you are one greedy little prick and probably proud of it..

I'm proud of him too.

ALL HAIL GIGA! KING OF THE MINERS!

You are missing the point. You are paying out dividends as if you are making a profit, but the only income you have is from mining bonds and you only count the coupon payments you receive, not the free falling value of the bonds you hold; you will have to sell these bonds at some point.  in reality you probably only made significant losses so far.

Wait until the first, I don't want to spoil it for anyone who isn't in the know.
