I know it will take some time but try and find what you can on Nvidia Cuda training...

Hi,
  The problem with launching cudaminer from within screen is an issue with shared library linkage against libcudart.so.

There are at least two ways of solving this.  One way is to change the cudaminer build system so that it encodes the shared library location within the executable.  To do this, I changed the Makefile so that the linkage looks like this in the two places where -lcudart shows up:
  -lcudart -Wl,-rpath,/usr/local/cuda/lib64

The second way is to hack the Makefile and change cudaminer to link against libcudart_static.a (which is an alternative you can use if you compile with CUDA 5.5).

Using either solution, the problems with screen go away completely and it works as it should:

sphere - johns:/home/johns/cudaminer/mine/src.20140228/CudaMiner-2014-02-28 % screen -dm ./cudaminer --algo=scrypt -C 2 -d "Quadro 6000" -l F28x16 -D --benchmark
sphere - johns:/home/johns/cudaminer/mine/src.20140228/CudaMiner-2014-02-28 % screen -ls
There is a screen on:
        5002..sphere    (Detached)
1 Socket in /var/run/screen/S-johns.

I think Christian should be able to change his autoconf stuff to allow either of those approaches without too much difficulty, but for the time being people that care can simply hack the generated Makefile to cure this problem.

Cheers,
  John Stone

Thanks for the reply. I am familiar with those posts, but they're pretty much only valid for the older (non-keccak) miners, with the new ones the launch configs don't work the same way (e.g. I can use T12x32 launch configs on the older december 18th 2013 miner, but only get 1Kh/s on the newer ones). My post 8096 proves it.

The readme file also doesn't mention much about scrypt kernels.

It's one thing that Nvidia isn't that good at mining against the red team, and its another thing that there aren't any good miners out there, to even take advantage of the little that the green team has to offer.

aren't there alternatives to screen, like the bg / fg commands? What if you started a shell script with screen that runs cudaminer a bit later, say after a 1 seconds sleep command?

reference these: https://bitcointalksearch.org/topic/m.4953208
http://www.reddit.com/r/dogemining/comments/1w4piu/cuda_miner_using_the_right_kernel_launch_config/ and you can use this as a resource for info
http://www.ozone3d.net/gpu_caps_viewer/

Also checkout the cudaMiner Readme file

I'll try this again, post # 8096 (Page: 405).

Does anyone know any good kernels for running multiple 780's for scrypt mining?

Hi Christian,

Dropping off a link to a gpu miner with a variety of algo support (AMD friendly). As the source is available, perhaps you could find a shortcut into getting new algo's supported in cudaminer, whichever they happen to be...

Hm, later realized this is based on sphlib, which might not be anything new for you anyways...

Off I go! Cheers,

Cleared 5 million today. Going for 10 million :-)

"Titties or Bust!" HAHAHAHA

I have almost done 64bit linux bootable image for Nvidia Ti 750.
(similar to BAMT - any person familiar with BAMT should switch very easy to this new OS)

The only thing which block the image upload - is this problem regarding detached screen with cudaminer.
Imho a significant regress - would be lack of automated cudaminer startup, in case of power failure for example or after manual reboot.
And there are plenty of BAMT based miners...

No offense to those desiring screen to work with cudaminer, but I have to say, it seems like there are more pressing "bugs" and features for Christian to work out first. But then again, Christian is the one who is ranking the request priorities here.

BTW, Christian, if you need any additional testing against riser related items, let us know.

But the problem is:  it is not running at all.
You can find result of your task above (bold)

yes three other pools, same stratum authentication error.

(and second observation: if you run screen and then you run cudaminer inside - all is OK)

motorboating. And I had to look up what it means in this context. *shudder*

I guess he is mining TTC

interesting observation, nur the root cause is still a mystery. Could be related to CUDA or could be something I did to the code...

are you a big fan of side boobs? Applause for sneaking this into my thread.

Christian,

cpuminer versus screen is OK
cudaminer versus screen is not OK
