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

[trell0z]

Well, I'm having some issues with the scrypt windows binary...

I was happily mining at 716kh/s with my GTX 780 Windforce at 1267mhz core and I tried higher clocks and crashed.

Then I restarted and whenever I try to mine scrypt cudaminer won't make my card go past 953mhz (stock non-boost clocks?).
I have a custom bios now that removes boost and can mine other coins at 1329mhz core with 1100mv only but cudaminer is still pegged at 953mhz core.

Any ideas?

EDIT: I second the donation part...cudaminer is my favorite mining program now, the dev is really ahead of the game.

What's your config for that? I'm doing 660ish~ khash with my 780 gb wf, at 1254mhz :/ Do you have extremely high memclocks also or?

Will there be a windows binary with keccak? Please?

We're severly under register pressure on Compute 2.x and 3.0 devices

but Compute 3.5 supports about 255 registers max!

So guys, you can compile the keccak.cu module with -maxrregcount=112. That is what the kernel really wants under compute/sm_10. Then run keccak benchmarks with x16 launch configs and check if it's any faster. I do not have a Compute 3.5 device handy right now.

do NOT compile keccak.cu for sm_30 - in my testing the hashes were no longer validating. And a faster speed is no good if your submitted shares are broken.

I will try to reduce the register pressure in the kernel if possible - the above suggestion might me a good workaround until this is done.

I will list the configuration for some Nvidia cards:
•GeForce GTX 560 Ti

cudaminer -H 0 -i 1 -l F8x16 -C 1 -m 1 -o stratum+tcp://yourpool.com:3334 -O [WORKERNAME]:[PASSWORD]
•GeForce GTX 660

cudaminer -H 0 -i 1 -l K5x32 -C 1 -m 1 -o stratum+tcp://yourpool.com:3334 -O [WORKERNAME]:[PASSWORD]
•GeForce GTX 670

cudaminer -H 0 -i 1 -l K7x32 -C 1 -m 1 -o stratum+tcp://yourpool.com:3334 -O [WORKERNAME]:[PASSWORD]
•GeForce GTX 780

cudaminer -H 1 -i 1 -l T9x20 -C 2 or -H 1 -i 1 -l T12x32 -c 1 -o stratum+tcp://yourpool.com:3334 -O [WORKERNAME]:[PASSWORD]


 prefix blocks x warps

 

Available kernel prefixes are:
•L – Legacy cards (Compute 1.x)
•F – Fermi cards (Compute 2.x)
•S – Kepler cards (currently compiled for Compute 1.2) – formerly best for Kepler
•K – Kepler cards (Compute 3.0) – based on Dave Andersen’s work. Now best for Kepler.
•T – Titan, GTX 780 and GK208 based cards (Compute 3.5)
•X – Experimental kernel. Currently requires Compute 3.5

 

Examples:
•L27x3 is a launch configuration that works well on GTX 260
•F28x4 is a launch configuration that works on Geforce GTX 460
•K290x2 is a launch configuration that works on Geforce GTX 660Ti
•T30x16 is a launch configuration that works on GTX 780Ti.

Christian I take it the one I have is fine to use? The 124Mhash/s I took a screenshot of?

Is there a way to configure a failover pool yet? So many pools having downtime lately, it would be nice to not have to change them when a pool goes down.

[shadypepe]

is it normal (i.e. caused by design of the coin) that i get half the speed for Vertcoin than for other coins?

Can nvidia geforce 7300 GT use this to mine?

[fcode]

Latest code gives me 60000 kh/s on the GTX560-448. Double what it was previously, awesome.

The card makes a high pitch squealing sound when running this though.

Ok, just tried on the GTX780ti, at L16 T192x32 and using maxregcount of what was indicated in your post, I get around 450Mhash/sec (with variation between 427 and 452) still running at 70% and at  876Mhz (not boosting))

(also tried with L128 with 128x32 got above the GHash (but I had two line one indicating 0khash and the next something above the GHash) so I assume it didn't work.)

I wanna test this on the Titan but haven't got the first clue where to start building for windows.

N=2048 is twice the amount of work compared to N=1024. Can you do two people's work without taking longer? If you can, you deserve a pay raise (or maybe you have been slacking in the past, lol).

So yes it's quite normal to mine Vertcoin at half the speed of regular scrypt coins.

is this for real? unreal!

no CUDA, sorry. A 7300 GT is good for minesweeper though.

•T30x16 is a launch configuration that works on GTX 780Ti.

This is outdated since the 2014-02-02 release. Kernels were swapped out (taking the ones submitted by nVidia now as default). The X kernel also is a different one now, running on Fermi. S and L kernels were removed.

Are you sure its 450Mhash/s??
Screen shot please :-p

[cbuchner1]

wouldn't you rather have 450 kHash/s?   try playing with the maxrregcount as I stated earlier.

[coolisbad]

Great news about the windows binaries, thanks a lot!

Any advice on what parameters to use with a GTX660 ?

yes it is (don't know how to post an image on this forum though...)  
we'll need to see if it still work like that on the real hash (I don't know how to post an image...
I hope I'll be able to solo mine this coin...
