Topic: [ANN][YAC] YACoin ongoing development - page 149. (Read 379983 times)
FYI yac.coinmine.pl has 19mh of the 36 on the network as of right now
my pool use original source code when it announce
is this a problem?
is this a problem?
Someone mining off-network attempting a 51% attack may have panicked when they saw me push the checkpoint at block 90000.
Where does one vote for best alt dev?
I am running the original client that was put up for download when the coin was announced. I am currently showing 91100 blocks total.
I'm using the original client too
i have a lower block count and im on the alpha client not the new beta version
Roger that. Looks like the timing was a coincidence then, and I won't revert the scrypt-jane library changes to the Github repository.
In that case the reorg is coincidental and my Github commits did not break compatibility with the existing blockchain.
At this point, I'm going to say it was a timing coincidence with a failed 51% attack possibly. Someone mining off-network attempting a 51% attack may have panicked when they saw me push the checkpoint at block 90000.

On that note, are there any win64 binaries available anywhere for these new client builds?
Everyone that's showing a lower block count #, are you on a version of the client prior to my Github commits of about an hour ago? I'm trying to determine now whether everyone having problems is or isn't on the client with the updated scrypt-jane library that I pushed to Github within the last hour. If anyone showing the lower block count # did not upgrade, then it isn't connected to the changes. If everyone showing the lower block count # did upgrade, then I'll revert the last 2 commits in the Github repository.
Bitcoin Megastore and eule, did you upgrade in the last hour?

and i think its unrelated to your update but YAC it has been very strange in the last 16 hours

I've got some orphans from past hour that had been accepted (included a PoS block).

Me too. I guess someone "precalculated" blocks to inject them into the chain, if such a thing is possible. The log i posted seems to imply that, but admittedly i'm not very good at reading logs. ^^ Everyone that's showing a lower block count #, are you on a version of the client prior to my Github commits of about an hour ago?

what's wrong with YAC, one hour blocks in my pool become to orphan.
and new find block
for example
http://yacexplorer.tk//tx/2bd44cc71eb9ad506c6bb27d7f613cfe60d0cb9c11cf60b32919bf08e557d781
seems orphan, but when list transactions, it show "immature"

Something is not right, there are 2 blockchains now and YAC explorer is on longer one, which is incompatibile with shorter one.
Checking vs. an old version of the client to see whether the scrypt-jane library upgrade merged from Joe_Bauers broke something with the block hash checks. Everyone hold on upgrading until we know for sure what's up.
I merged a large set of changes from Joe_Bauers to upgrade to a more recent version of the scrypt-jane library (hopefully easing some of the Windows QT client build problems). I also added a checkpoint at block height 90000.
Everyone upgrade somewhat cautiously since there were quite a lot of changes to the code, and report if they broke anything. A Linux build seems to be performing correctly for me after the changes, but I'm more unsure about whether anything broke on the Windows side.
Joe - I left out the RPC port change from 8332 to 8108 for now. Main concern is that anyone that didn't explicitly specify rpcport= in their config file might have things broken by changing the RPC port (and worse, might not know that it broke). I think if anyone is running the Novacoin client on the same box, then for now, they may need to manually set rpcport= in the config file.

maybe time for a YAC pool with stratum now the gpu miner is out, getting quite a few stales
I was trying to modify eloipool to work with scrypt-jane but I've got segmentation fault errors and I don't know how to debug it (I am not skilled at all in python). In my opinion problem with high stale rate is because for some reason (scrypt-jane dependant calculations?) both pushpool and yacoind are very hungry for resources - CPU usage in average ~10 times higher than other coins. Even if my server is 8 core with 24 GB RAM it creates some delays internally which leads to stales...
I find each time it hashes, it will allocate the memory buffer (call scrypt_alloc) and scrypt_free at the end of hash. Will it impact the performance when there're so many threads processing? How about make this memory buffer becomes thread-local to reduce these memory re-allocation?
Otherwise, I can't find more difference of it between the yacoin & other scrypt coins.
If you are asking me - I have no idea how to do this
but I can easily test it if you can provide example.I made the change of code by using boost's thread-local facility. Here is the patch against the current git: https://github.com/yacoin/yacoin
http://sourceforge.net/projects/hnindev/files/yacoin_mem_opt_patch.zip
I've locally built the client, it works no error.
tested it but it works even slower - there must be also a different issue: I suspect few users on my pool are using botnets to mine yacs, which lead to lot of requests to pushpool...
I set up another pushpool instance on port 8888 - can anyone point a miner to this port and check accepted/rejected ratio?
