[ANN] cudaMiner & ccMiner CUDA based mining applications [Windows/Linux/MacOSX]

[cbuchner1]

@cbuchner1 I have compiled a few versions of CudaMiner (along with instructions) for Mac OS X users: http://www.johnchapman.net/cudaminer/

I plan to compile an OS X version for each future release (as long as they compile ;-)).  Thanks for the great work!

Wow! This is great. I put a link into the first posting.

I now have 30 kHash/s working for me. I think I am pulling more than a kilowatt of power now. Eeek. I am global warming.

Sorry im very noob into this, would be nice if anyone would post a working version for Gpu/Windows 64

[bathrobehero]

Also, does memory amount on gpu matter?

For scrypt? Not so much, but for scrypt-jane it does matter.

Is Scrypt jane heavily dependent on memory available? If so how are 6GB Titans performing?

I think Titans have a problem allocating all that memory.
Quoted from the Scrypt-jane spreadsheet:
"GPU Memory usage: 2883 MB"
"Seems Kepler Kernal has better memory allocation then the Titan for Scrypt-Jane. Texture Cache set to -C 1 throws an error indicating it fails over to -C 2 but if you launch a -C2 the hashrate is nearly halved."
Edit: Also "Current Titan kernal appears not to allow much more then this before driver soft crashes currently."

I believe one was shared a couple of pages back.

More like global warning..... to ATI/AMD!
........ok, I stop.

That one was crashing my nvidia driver (gtx 560 ti), im guessing it crashes more people... :/

I see that someone has "released cudaminer" for vertcoin

https://bitcointalk.org/index.php?topic=404364.msg4620453#msg4620453

at least with a better ratio than the buggy AMD implementation vs scrypt - would have been gentlemanly if they had tipped their hat to Christian for all his effort.

Any news on the vertcoin issue?
latest github version still gives me the following error:

Unhandled exception at 0x000007F679AD8A64 in cudaminer.exe: Stack cookie instrumentation code detected a stack-based buffer overrun.

Seems something related to cpu memory management.

Crashes with Win and Linux.

I know there are maybe more important things to do but vertcoin is already looking very promising.

Not sure which issue you are referring to ? The post linked to in the post above (yours)  has a working version for windows - there was a slight change for vertcoin apparently.

I believe the CPU based validation code has some kind of hardcoded scratchpad buffer size for N=1024. This needs to be fixed.

EDIT:
oh look what's there !

Code:

scratch[32768]

EDIT2: okay, a likely fix is now on github. mine away!

You are the best!

I will report how vertcoin performs.

[cbuchner1]

I will report how vertcoin performs.

the current github is not reaching the speeds of the 2013-12-18 release, which is kind of a mystery to me.
So your vertcoin mining might be a bit slower than expected.

Fixing this will be another important milestone before the next binary release.

Getting about 81 kh/s on a 770M (910MHZ)  vs 214 kh/s on a R9 270X (which was getting 450 kh/s on "normal" scrypt and 2.9 kh/s on YAC) - Impressive

Could this be a 32-bit limitation? Maybe we need a working 64-bit version?

[cbuchner1]

"Seems Kepler Kernal has better memory allocation then the Titan for Scrypt-Jane.

don't think so. Features for the Titan kernel have been brought to the same level as for Kepler.  Just -C 1 and 2 aren't needed for Titan, as caching is automatic and always implied.

Tried Vertcoin just now, but I am getting CPU validation errors with the latest git build.

2048 is the current N value right? This is what I'm using for settings:

--algo=scrypt:2048 -i 0 -d 1 -H 0 -l T12x32

thank you for noticing

in the CPU validation code I just changed

j = 32 * (X[16] & 1023);

into

j = 32 * (X[16] % N);

so it should work correctly for ANY N, even non powers of 2.

Awesome, it's working now

Is vertcoin any profitable? I mean I'm not sure how much it says, but the average hashrate per miners of the biggest pool is over 700 kH/s.

I'm getting 220 kH/s per 780 which compares favorably with the 340 kH I get from a 7970.

1000 kH would get you 500 coins per day at the moment, at the current sell price that's around 0.08 BTC per day. So yeah very profitable assuming the value holds steady, maybe the most profitable coin out? Seems better than Doge even.
