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

[cbuchner1]

Linux 64bit finally compiles. Thanks.

But I don't have a titan card, nor the cuda 5.0. So it still show compilation error:

titan_kernel.cu(59): error: identifier "__funnelshift_l" is undefined

Could you help me out here?

If you don't have the CUDA toolkit 5.0, you need to remove the titan_kernel.cu module from the makefile and make sure its functions aren't called anymore.

Alternatively compile this kernel for compute_20 or sm_20 and remove the offending statement - the kernel will be useless but without a Titan card it's not going to be used anyway.

I know this program is focused on scrypt mining, but could it be easily adapted to build a newer CUDAminer for sha256 coins? Just think such a program would be more suitable than CGminer for the nVidia people and would help sway me to get a nVidia card for my next build.

there's already a CUDA based sha256 miner, which does 300MHash/s on Titan cards - a bit less on other models. A few posts back its thread has been linked to.

Fair enough, I'll have a look for it.

Code:

[2013-04-22 19:29:45] GPU #0: GeForce GT 430, 107520 hashes, 22.23 khash/s

first coin goes to you thank you!

At your hashing rate, a quarter will do

300 now with 98x3, n1

okay so there was a small improvement with the latest Titan kernel changes. So let's keep these changes! ;-)

Hi,
I'd like to start by saying that your program is awesome And of course, I have already donated my first LTC to you.
However, what would further improve my mining experience (except from speed improvements of course ) would be stratum.
I am willing to put out 5 LTC as a bounty for it. If others want to join in, they're welcome to do so of course
So long,
Tobi

Totally agree, I'll donate 50 FC (have < 1 LTC )

[cbuchner1]

the new power supply makes all the difference. It's a 500 kHash box with no overclock



EDIT: draws more than 800 watts though. Almost replaces a space heater

[Tobi042]

Oh and btw: This miner can definitely be also used for FeatherCoin mining. I tried it and it worked (FC is pretty much the same as LTC and because of that scrypt-based)
@cbuchner1: If you set up a donation address you will get some of them from me too Oh and maybe edit the thread title so it becomes obvious for noobs

I can't get that one to work =/ and no one can seem to tell me how to fix my error when I try to compile the modules again for me.

His address is on the first post :

It also in the program when it runs

[cbuchner1]

I think he meant to donate feathercoins. But I am not into feathers really. My fetish is somethin else. Heck, I am not even sure if I even have a Bitcoin wallet at this time.

I am currently looking at the PTX assembly of the CUDA kernels and I see a lot of indexing calculations into shared and global memory. Lots of multiplications in particular. I am going to check if I can reduce these to gain more SPEED.

Christian,

I used the 4/22 ver.2 build and it restored the Titan performance to previous levels.

[cbuchner1]

I "found" some more 20kHash by means of optimization. So my 4 GPU box now jumped from 506 kHash to about 526 kHash. But I fear that I may be approaching the limits of what is possible. The PTX code looks rather dense now.

[falconae]

Is there a deffinition of all the launch configurations mean? in the readme it tells us what the "S" and no "S" are but what is num1xnum2?

I'm asking due to trying different ones on my crappy card and have gotten the up to 170Khash from 15 but I get a does not validate on CPU error

Well, suit yourself.
(points to name)

Oh, and to the other Falcon (above)... it's in the readme. If you're getting a ridiculously high hashrate, it's crashed due to bad options, but it's not stopping. "S", well, I haven't seen "S" do anything good. It's in the form "hashes x warps", though I don't know what "warps" are - I think "hashes" refers to the number of operations it tries to run in parallel. Too much at once and it runs out of memory (watch for the "uses too much memory" error in the output before it starts running).

[datguyian]

is there any way to determine where I can (safely) set my texture-cache variable? I'm mining with a Quadro 4000, for all I know this may not even be possible with the card. I'm getting about 73kh/s just using -l 48x5 right now (the best I've managed with any configuration).

I swear, if it had teeth, I looked at that paragraph over and over and just simple failed to see it...sheesh

thanks for the answer though, it makes sense I just could not "see" it crashing like with guiminer when it would crash my screen would flicker for a driver reset and then it would be reporting Ghashes.
