FYI quick teaser for you Wink

About 10 minutes ago I managed to close timing on the 175Mhz build. This means that according to the Xilinx tools, I have a viable 175Mhash/chip bitstream that should run stable on all 4 chips.

Now comes some additional work required to ACTUALLY run it on a hardware and verify this. And I need to test it for stability for 24h or so. So we're not "there" yet, but this is a fabulous leap forward. In addition, my machine is still chewing on it optimizing, and hopefully it will squeeze another 0.75ns out of the clock cycle. Which means I could push this to 200Mhash and keep it within "spec" (and honestly, the one enterpoint is testing now is using worse clocking code, and was out of spec by over 1.5ns and it was still semi-stable for them, showing the cairnsmore hardware can run a bit out of spec if needed).

Anyway, just a quick update, to be clear this is NOT yet a stable bitstream, but it's a jump forward. And barring any major bugs, within 24/48h I hope to deliver much better news to you Wink


This may be perfect timing. My CM1's are scheduled to ship this week Smiley

My 5 btc to this cause, is simple. I'd want the CM1 to be working to it's fullest potential quick as possible. While also ensuring if I'm paying this bounty, I'm keeping this an open source project. It would be more, but that is all I have in btc right now.

Aslong as a bitstream exist that is open source, uses all 4 cores and does within ~90% of what many of us expected the CM1 to do (800Mh/s) without any outside infulences. It doesn't bother me, if enterpoint makes use of, or even pays in this case Glasswalker.

I am part of the community that cares about results, the means of those results I am not too fussed by. It allows the community at large to make use of the bitstream, aswell as see the bitstream be improved in an open source way that has work so well with other projects so far.

Glasswalker will probably win the bounty, but whom ever it is, is soon to get a long of bitcoins, as their is a lot of interest in seeing these full operational that is for sure.

2BTC pledged as I have 2 * CM1 right now

do we give this to a 3rd party or straight to the winner once bitstream is tested?

Think Isokivi is only acting in an organiser capacity. Aslong as the winner states his bitcoin address I'm sure the rest can be done from there.

Yes, I will not be holding anyones money. Im not a long enough time member, nor well enough known to do this, should a figure the community trusts step up, it can be done, but for now I expect everyone to pay their pledges separateley when a bitstream qualifying is out.

I think we should have a member of the community holding the bounty in an escrow account to ensure the winner gets all pledged btc. someone w/ rank step up.

Voting for Zefir. A really trustworthy guy who is running a solid mining bond on glbse.

Of course only if he is willing to do the escrow.

2nd proposal is Chefnet - he also proved himself as very trustworthy for selling lots of stuff on the forums.

Thank you for your trust and support. If majority is fine with me, I'll do the escrow.

In fact, I think the coins should be collected beforehand, instead of waiting the bitstream to be finalized. Due to the persistent dynamics in the Bitcoin world, too many potential events (like BTC skyrockets to 100$, pirate loosing all our coins in Vegas Wink, etc.) can make it harder to collect the coins later people are willing to contribute today.

If everyone is ok, I'll set up an offline address for the bounty and a Google Docs spreadsheet to account the contributions.

Cheers, Zefir

Ok folks, here we go.

I have put up a spreadsheet where I will account the contributions for this bounty.

The coins will be deposited to 1CM1bj7jxVskkvKE2kcw6L16rHMXL38aFm.

I am not going to send every contributor a personal address for correct assignment. Instead, send your money to the given address and at the same time PM me (forum mail to zefir or via email) with how much you contributed. That should be enough information to match the payment to sender.


Did I forget something? If not, let the coins roll!


@Isokivi: could you please copy the related info to the first post? Thanks!

Let it grow up fast and we will have a first (smaller) bitstream today!
I think the faster and bigger the Bounty, the faster we will have the goal!

That's an internal information, the announcement will come shortly form the bitstream guru and he's only working 3 day's on it =D

Sorry! couldn't resist!

3 ppl agreeing on the escrow is just not enough, imho. I have nothing agaist zephir, nor can I say anything for him. Just havent paid that much (or any) attention to he's doings in the bitcoin world. So ramp up some more support and I'll change the post.

Just a quick update, I now have a copy working at 175Mhash/s stable for a long period. But there are still some issues with the controller that are impacting communications (which is contributed to a bit by the serial comms code that ngzhang used on his core as well, which I've modified, but it's still based on the same design).

Enterpoint has released a new controller which will solve some of the problems, I believe it will work on 3 of the 4 FPGA positions stable, but I have to do some tests on this tonight before I release the actual bitstream.

In the meantime I've started another round of improvements based on what we've learned, and hope to have an optimized build soon.

Sorry for the delays.

Eberon: only 3 days and you have a working bitstream?  Shocked that's pretty amazing. Is it based on one of the existing opensource builds? or written from scratch? If so I'm curious what fMax your getting on the chips? (or did you just get super lucky and it closed timing on your first try by fluke lol). Also has this been tested on the actual cairnsmore yet?

I'll post an update once I've done testing tonight.
