cbuchner1, what's your next target in your TODO ? Cheesy
Implementing native stratum protocol would be so great.  Tongue Cheesy

Getting some error handling in there, and fixing that CPU overutilization bug that I found.

So far I haven't really been able to speed up the CUDA bits. I've tried but failed Wink

Does anyone know a good documentation resource or reference about Stratum?

Seems like the official stratum site is down right now, but you can start here:

Implementing native stratum should be really low on the priority list.

There are stratum proxies anyone can use to connect to any pool that relies on stratum.

Please focus on the stuff that really makes this miner unique (CUDA/CPU code optimizations)! Smiley

I'm adding cudaminer to guiminer-scrypt right now, the stratum proxy is already there so you don't need to worry about it for now.

just saying...

The largest donation I've received was 40 litecoins (thanks!). That motivated me add Linux autotools support real quick. It took some extra time and third party contributions to also get 64 bit Linux compilation working.

So far I've accumulated about 75 litecoins. About 20 of that was mined by me, the vast majority is donations.
I still rely on my day job to buy food though Wink

Unfortunately mining difficulty has increased so much that it's no longer worth the electricity to mine myself, even at $4/LTC.

Thanks everybody!

P.S.: Anyone interested in a 64bit Windows version?
Would it also make sense to offer a non-Titan Windows build that relies on CUDA 2.3 (with much lower driver requirements)? Maybe it could improve the slow speed issues people are seeing with compute 1.x devices

Update the first post with donation address. Call it motivation addresses or something Smiley

I will send you 10 LTC. And hopefully in a year they will have greater value.

Great work.

Psst.. Got Ether?

I think the output is quite normal. From litecoind it gets work for 5 seconds, does that and prints out stats. Then it gets more work, etc...

at 20kHash/s: https://www.litecoinpool.org/calc?hashrate=20&difficulty=437.9378214

Time to Find a Block:  Expected Time   1088 days 12 hours

Do you really want to run this for 3 years before finding just one block at the current difficulty?

Was just seeing if I had it setup right

Anyway its running on background of work comp for feathercoins might get lucky

Wooha! I found out why my GTX 660Ti is never pegged at 99-100% load, but instead fluctuated around 75-95%.

Let me verify how my latest changes affect my other GPUs. Maybe we need some special code paths just for Kepler devices.

Let me know if this works or fails for you. Post your GPU specs and achieved kHash/sec please. Also let me know if you experience any crashes or if you have specific suggestions for improvement.

Works great for me, GTX 460 getting about 105-110Khash/s.

Just one question, does CudaMiner support Stratum?  My pool supports it but I have been unable to get the two to work together yet.

EDIT: So you can add to your info.  I autotuned it and it's running on Win7x64 and was using the 4-22 miner.  I just installed the 4-30 miner and am 105-108Khash/s now.

Currently you need to run a proxy for stratum.

I was.  I was pointing Cudaminer to the proxy then the proxy to the pool and was getting error messages from the Stratum proxy saying it couldn't understand the requests from the miner or something like that.  Will have to set it up again and get a screenshot of the message.

So Stratum was connecting to the Pool fine.  But the break was Cuda connecting to Stratum.

sounds like your pool is having problems... I have cudaminer running with stratum_proxy and it is working just fine. Verify that your stratum_proxy is working by testing with cpuminer running on 127.0.0.1:8332

Also important is making sure that stratum proxy starts with -pa scrypt e.g. mine looks like:

Code:
stratum_proxy.exe -pa scrypt -o fc.altpool.com -p 3333
pause

Has anyone run this miner with GTX 590s? They're not listed on the results spreadsheet.

I'm especially interested in finding out whether cudaMiner will correctly identify the two GPUs - one GTX 590 is basically two 580s stapled together and underclocked.

I was using localhost instead of 127.0.0.1 and I didn't use the -pa scrypt

Will try again later tonight.

That sounds like it was the problem... cool. Good luck!
