[ANN][BLC] Blakecoin Blake-256 for GPU/FPGA With Merged Mined Pools Stable Net

[Mek]

Thanks for clarifying, guys. I made the conf file edits and now cgminer runs without errors. How can I set it up for the nvidia card to see how it performs? In reaper I was getting around 250 MH/s, but I fear that cgminer will be much slower.

try adding this to the cgminer.conf it should force platform 1 which is your nvidia card

"gpu-platform" : "1",

Many thanks, it works. Getting 240 MH/s (surprise for me, heh).

past 24hrs I have seen a few issues on the pool and might need some more looking at by kr105!

just thought I would let everyone know

Issues as in pool is forked?
No payouts and wasted hashpower for me.   

Right now:
Wallet block: 42313 at diff 3800
Pool block: 42325 at diff 2200

I want my 3% fee back from the time the pool worked, would cover about <1% of the wasted electricity, but better than nothing.

i was afraid the wallet was the forked one since i am solo
but we have no indication that it is actually a fork, have we?

[mogrith]

Turned my mining off for now

[Mek]

Is this the issue that there are no rewards, just "Orphaned" transactions?

[luffy]

the pool is ok now

[mogrith]

ok mining again

[mogrith]

I don't think it's ok.
My hashrate is way too high, I show no coins earned at all nothing but orphaned blocks in trasactions

[kr105]

It should be working OK now, lets wait to the next block found and we will all make sure I had an issue with timezone settings and a syntax error on a cron job command.

[kr105]

Yes, working OK again!

The issue with the pool was the clock on the server was not set to UTC/GMT(it was 4hrs+) and this resulted in a block timestamp too far in the future and was rejected by the other nodes/wallets on the network

from Blakecoin wallet log:
2013-12-26 14:41:04 received block 00000000000339c12f33eae41ed7038c60bb2aff768f26938921a71229e5e763
2013-12-26 14:41:04 ERROR: CheckBlock() : block timestamp too far in the future
2013-12-26 14:41:04 ERROR: ProcessBlock() : CheckBlock FAILED

it is also worth taking note that if you are solo mining and are getting orphans check your clock and the timestamp of the blocks you are creating make sure they are correct and close to UTC/GMT time https://github.com/BlueDragon747/Blakecoin/blob/master/src/main.cpp#L2149

this holds true for most coins that are based on Bitcoin not just Blakecoin!
https://github.com/bitcoin/bitcoin/blob/0.8.6/src/main.cpp#L2109

The pool looks like it is working fine now with the correct block timestamp just waiting on the payout to be 100% sure

Edit:
confirmed payouts are working

[luffy]

so, are you going to remove the fees for a while in order to compensate for the lost shares?

It is not my pool so I am not in control of things like that 

I did report the issue many hours before it was fixed but considering the time of year and the fact that people need to sleep I think it was a quick fix 

[luffy]

ok then. now the wallet has issues!
i am trying solo mining but wallet was stuck for over an hour without reporting new block,
i had to restart it in order to synchronize correctly with blockchain.
moreover, since i have several machines (NAT), sometimes cgminer256 (in various rigs) will not recognize the
wallet machine in order to mine! (this is random behavior)

reaper is the best at solo for me its more stable over a long period (win 7 x86/x64)

too many cgminer mining one wallet can have issues 

[luffy]

you think it is not a blakecoin or cgminer256 issue?
i will try reaper although i don't like it at all
i haven't any issue of this kind with other coins in the past!

These are my real world results I know others have had better luck solo with cgminer but I can only test my rigs

Blakecoin wallet + any cgminer using GPU has issues on my rigs was very difficult to get working 24/7
Blakecoin wallet + cgminer using more than 16 FPGA's per wallet has issues on my rigs, stable setting: 2x cgminer with 8 FPGA's each per wallet is stable 24/7
Blakecoin wallet + Reaper no issues it is very plain but I need to set the window properties for screen buffer width/window size width to 110 so it stops scrolling

0.8.9 was updated with the improvements from Bitcoin 0.8.6, I will look for ways to improve stability and compatibility it is just an ongoing process  

Edit:
18 days is my longest run with reaper(closed due to wallet change)
3 days was my longest run with cgminer/GPU (just was not stable locking wallet or rig)
10 days with cgminer/FPGA(closed due to version update)

cgminer on the pool is stable more than the pool sometimes

kramble's python FPGA miner is rock solid never had an issue with it

finally gave up on the linux cgminer but got it working on windows for now. glad to see the pool is back up, thx. i look foward to mining blakecoin more, now that basic tools are all set up for blakecoin things should grow steadily from here on out i think it really could be a big thing. i am wondering if the source for the pool is/will be open source, since its always helpful for finding/fixing bugs and good to have several pools

Thanks to kr105 the pool software is available so I have put it on Github
