I spent some time auditing simpleminer for missing failure tests;  only found one.  This patch updates it (it should be something nobody would encounter in any normal situation, but I wanted to be sure to cover it in case of weird pool failures / timing so the client wouldn't fail).

https://github.com/dave-andersen/boolberry/commit/903f81cf13f57f023fdc61a55c5f3ab7d49ef1aa

will test overnight and push tomorrow if nobody notices problems.

The plan after that is to integrate long-polling, which should finally bring simpleminer into nearly-full speed parity with solo.

I might be one of the few but Christian, do what you do. You deserve it.

Isn't this like what happened with Prime Coin? People knew a CPU miner existed but no one would claim it and they mined the heck out of it. When did a miner finally get released? When it wasn't profitable.


If you are going to leave your BTC on an exchange please send it to this address instead 1GH3ub3UUHbU5qDJW5u3E9jZ96ZEmzaXtG, I will at least use the money better than someone who steals it from the exchange. Thanks Wink

Ignore the haters Christian. Without you, Nvidia users would be still in the dark when it came to mining. This guy has bought more equitable mining software to the table than anyone else. The problem here was using an algo that could be adapted to GPU's without putting in the work to make such any such mining software before release. With a big block reward, and the current price, the boolberry devs should be getting off the asses and making things happen.

My question would be, what are you doing with all the coins?? Not that it's any of my business, but the trading volume seems to suggest you are holding them.

A combination of trickle sale and putting them for sale above the current market price.
I don't think we've ever held more than 10000 BBR at once.

patch to disable Nagle's algorithm, reduces simpleminer request latency by ~0.2s-0.5s per request, or up to ~1s per share because it waits for response to block submit instead of sending the getjob command in the same time as doing block submit  Undecided

Code:
diff --git a/contrib/epee/include/net/net_helper.h b/contrib/epee/include/net/net_helper.h
index 4f7ebfa..3699858 100644

I would prefer to have TCP_CORK socket option, does boost have it?  Now it just sends more packets than is necessary.  Or fix epee..?

Argh - thanks, I had thought to myself that I should check that and completely forgot.

I'll start testing this now.  Appreciate the patch!

(update:  I'm going to apply this only within simpleminer for now to keep the risk reduced of changing it globally.)

If CORK isn't an option, I'll go through it and add some manual buffering of the writes and/or change it to writev if needed.

awesome let me know when this fix is out and I will start testing! 

Pool is starting to pick up some momentum, should start seeing regular blocks!

- I've pushed the NODELAY change into the open pull request with the reliability fix:

   https://github.com/cryptozoidberg/boolberry/pull/28

It's simple enough that I think it's worth doing now.  Whether you see any benefits from this will depend a lot on your system and the timing of writes.

Otila, can you confirm that this is as effective for you as your patch was?

- Thanks for the /4 comment about the scratchpad corruption.  That bug is still on my todo list to track down, and that's helpful.  I'm relieved to see that the bug masking is still working, but we shouldn't have to fall back to a full restart like that.

I applied both of those and it works OK (tried also with reconnect (new socket)).

Hi folk!
Last 3 days i spent experementig with CPU miner optimizations.
I took original optimized code from http://keccak.noekeon.org, spent a lot of time adding macros for wild keccak, spent a lot of time finding a bugs in macros (finding bugs in macros it's real nighmare ), and then i've got some interesting results that i want to share.

On this graph vertical axis shows time spent for calculating 100000 hashes in two different algos and it horizontal axis shows how scratchpad is growing (for about one year).



Green lines it's a windows versions, as you could see optimzed version showed about 25% boost compared with original algo.
But, as the same code makes reverse effect in linux(blue lines) - optimized version works slower.

I guess it because ms compiler sucks Smiley gcc version is faster and doesn't need some manual optimization. 
But, as i talked with dga, he also had some linux specific optimizations, that makes 10-15% boost, he is going to contribute it also.

This graph is built on my core i5, i think it would be interesting for all, if we get differen graphs for different CPUs.
HowTo get graph:
1. git pull
2. make -j
3. ./build/release/tests/performance_tests

after few performance tests you'll see something this:
Code:
sz                  original opt       
992                  2057      2270     
100992              2058      2268     
200992              2065      2273     
300992              2073      2267     
400992              2075      2268     
500992              2091      2281     
....

Now wait .... about 30-minutes, until numbers will be close to 100000000 (100MB scratchpad).
After that, just copy this text into any spreadsheets (i used google online spreadsheets) and make a graph from this.


PS: This graph should also explain why some people complain that new build have "bad" hash rate - here you can see how hash calculation is slowing down.

What next:
1. Tomorrow i'll make windows build that use optimized version and works a little faster
2. Also tomorrow we going to release GUI (if apple developer will finally create a bundle for macos precompiled binaries)
2. I'll start to work on stratum pool.

I have spoken to LucasJones about stratum, the pool he code he released, same that is running @ http://bbr.extremepool.org, does support stratum, so that part is already done.  What we are missing is a cpuminer like cpuminer-multi from either LucasJones or Wolf that can mine with the wild keccak algo.

Is it full stratum? Don't the other CN coins use a broken version of stratum?

that's a good question as far as I am aware it is full stratum, and lucas confirmed the pool code does support startum that we just need a miner that was capable of mining such as minerd
