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

[mmmaybe]

ok the new webserver for cudamining.co.uk has been set up and is running. Please let me know if you notice and downtime, slow page loads (more then 500ms) and any issues/error mesages

I have also modified the design slightly so its easier for web browsers to load and mobile devices will have a better time.
I hope everyone viewing the website on a mobile device likes the new menu

Thanks for your continuous work, site seems fast and stable 

How about having the files stored, or maybe backed up, on the local server, in case the external storage would be deleted? I think someone brought up that idea earlier?

[bigjme]

I mentioned the option not long back.
Didn't get much of a response though

Hmm 980 seems to be 33% faster then my 780. May be worth it after all. Even after I get robbed for being in the UK

you need to show the error message from the compiler (few lines before what you show)

Looks like I need to set the path to mpir for the make file it seems.

the compiler doesn't find mpir, a nice tutorial has been posted a few page back (yesterday actually)

found it: https://gist.github.com/zcshiner/4b32980792d367222304

Thanks again
echo "export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH" >> ~/.bashrc
Fixed compilation.

When I run ccminer I get:
./ccminer: error while loading shared libraries: libcudart.so.6.5: cannot open shared object file: No such file or directory

I'll figure it all out eventually

you also need to add /usr/local/cuda/lib64 to LD_LIBRARY_PATH

Got that set in my bashrc now.

something is wrong with your drivers. The installation process can be tricky sometime

Why will you be robbed if you buy it in the UK...? VAT or something?

Don't know if we have any American College Football fans in here or not but I just seen that there is a new bowl sponsor this year: BITCOIN St. Petersburg Bowl

[miner256]

I have CUDA 6.5 installed and mpir 2.7 alpha 10, what should I delete from Makefile.am ?

The edit of Makefile.am just decreases compile time by not bothering with anything other than compute_50.
Find any lines with compute_50 and then delete the other options to leave you with just compute_50 like this:

$(NVCC) @CFLAGS@ -I . -Xptxas "-abi=no -v" -gencode=arch=compute_50,code=\"sm_50,compute_50\" --maxrregcount=80 --ptxas-options=-v $(JANSSON_INCLUDES) -o $@ -c $<

This means it will only work with compute_50 but it will compile very quickly.

I'm using Ubuntu Server 12.04 with CUDA 6.5 and Nvidia drivers v340.32.
With the latest version of Cudaminer source, when I attempt to run the mining script I was using back in December, it says "unable to query CUDA driver version! Is an Nvidia driver installed?"
Is there a symbolic link I should make somewhere, or maybe the 340.32 drivers don't support CUDA 6.5? Does anyone know?
Nvidia also has 343.13 beta drivers, but I don't want to use the beta unless I need to.

Prices are usually higher there to start with, then you get extorted with VAT.

Yep. $900 US is some how £759 in the UK. Even with a 0.63 conversion rate xD

NVIDIA GeForce GTX 9 series performance
http://videocardz.com/52166/nvidia-geforce-gtx-980-gtx-970-gtx-980m-gtx-970m-3dmark-performance

Which one of those do  you think will be the new 750ti, I mean not necessarily the most powerful just the most efficient for mining?

[bigjme]

it depends if talk is right, and if those results scale with mining performance.
If so, the gtx 980 is the same as 3 750ti's power wise.

performance wise a 780 is 3 750ti's, and a 980 is 1.3 times a 780, making a 980 the equivalent to 4 750ti's and the power usage of 3, plus only a single slot card

I may be wrong but that's how i see things, although i do think their graph is most likely incorrect

[Epsylon3]

I just want to make a small announce if you missed it :

You can find my "new" ccminer fork for blake (NEOS and SFR) and blakecoin here :

This algo seems to report nice hashrates on pools, and ive put inside a protection to prevent useless recomputing of the same blocks.
GPU Usage seems limited à 90% with small pauses when the pool does not send new jobs, which reduce the Card(s) heat.

Reminder: SFR (SaffronCoin) wallet has a bridge to buy coins via Paypal, its nice to play with some money on exchanges.. promising

That is awesome isn't it?

Do we have any idea what the 980 may retail for?

Under $500 USD is probably wishful thinking...

Wow nice. I will ask whether djm could merge your changes in his next release. Thanks.
