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

[bigjme]

Ok thanks :-)
My miner seems to sit around 2.77khash/s now. Its on 75% so 3 of 4 accepted. I now have 3 transactions but my wallet is still only showing 2 qctual and saying 3 at the moment. So right now if tye 3rd was real im at 150yacoins when they mature

I am breaking some speed records for Yacoin mining today

WOW. 1.96 kHash/s on GT 750M with 4 GB DDR3 VRAM using latest github code. -l K2x8.   This is a laptop. And it's only using 2077MB out of 4096, including running an Xorg display on Kubuntu 12.04 64bit. And the device remains usable even while mining without the -i 1 flag!

I think the equivalent desktop part would be a GT 640 with 4 GB DDR3 memory. On my testing with Windows I haven't seen those 1.9 kHash/s so far.    My next mining build might consist of a mainboard running 5 GT 640 cards with 4GB each.

On my 780 Tis I think I use -l T4x4 (EDIT: correction. It was -l T7x3 but -l T23x1 is actually slightly better) to get 3.2-3.3 kHash/s. I will check again when I get home.

High end cards are partially idling when doing scrypt-jane. It might be possible to do simultaneous scrypt-jane and scrypt mining, to use all resources on the cards. However it would require some very smart multithreading logic, and  simultaneous execution of kernels on the GPU.

Thanks :-)

Would be great if we could get it doing lots at the same time. Although my 780 seems to be siyting at 100% usage although I have the intensity set to 0

[dogelimic]

Are you using the latest version from git or a binary release? I see a commit message on Dec 28th that says "add back support for chunked memory allocation and texture cache to Kepler kernel. Slight speed-ups with -C 1 are seen." which implies he removed it at one point, possibly when upgrading to CUDA 5.5.

Was using the latest binary, the 12-18 release. I'll try compiling from git, thanks.

edit: Is there a guide somewhere to compiling on windows? I got all the components but I'm unsure what to do with them.

[bigjme]

Using T4x4 with -I 0 gives me 2.88khash/s in windows 7. It does cause my drivers to crash when it initially loads but they then recover and my gpu is still 99% and 2.3gb of memory used. So I take it that the miner is still running as they normally hang after a driver crash.

So a 660ti is faster at this then my gtx 780? Whyyyy? This algorithm is going to take a lot of work to figure stuff out. Although, are we finding better speeds in linux then windows?

I stopped trying to get the linux version running because I couldnt get cuda 5.5 to install for me in ubuntu 13.10 so I dont know if it is getting better performance or not

Edit: I didnt trust the T4x4 because of the driver crash. T14x1 is what auto tune sets me with around 2.7hash/s and no driver crash. I did try T10x1 and T20x1 which were posted earlier but they gave hash rates of about 1.5khash/s for me and crashed my driver aswell. I am using the lastest windows 7 driver for it

I am also mining using a 64 bit compile which may have effect as 32bit made a huge difference on the official cudaminer release

EDIT 2: ok so i am going to follow the example Treggar posted on compiling this, i am using Express 2013, but i do have every other version, free from my university ;-) so i am going to try and compile my own 32bit from that. The instructions i will be using are as follows;

1) Install visual studio 2012 express (free from microsoft)
2) Install the cuda 5.5 toolkit (free from nvidia)
3) Download libcurl source & read the README on how to build the library for windows
4) Download the pthread library for windows  - I downloaded prebuilt lib
5) Open visual c command prompt & build libcurl library  - I built static lib and included it in the exe
6) Clone the git inside visual studio
7) Edit the properties of the project to include the libcurl & pthread includes & libs
Build release
9) Profit from YAC!!~?

Is it normal that cudaminer is not using 100% of gpu ram? Using normal scrypt mining

[Treggar]

Don't waste your time with 2013.  Cuda 5.5 toolkit is not compatible.

[bigjme]

so 2012 100%? and i take it that i will need to compile it all on my system with the gpu in it? cant d it on my laptop for example?
and how do i clone the git into visual studio?

i figured out the lib curl install from their guide which literally states to run the command prompt and "Then run 'nmake vc' in curl's root directory."
once i know how to clone the git i should be ready

perfectly normal.

Edit: I didnt trust the T4x4 because of the driver crash. T14x1 is what auto tune sets me with around 2.7hash/s and no driver crash. I did try T10x1 and T20x1 which were posted earlier but they gave hash rates of about 1.5khash/s for me and crashed my driver aswell. I am using the lastest windows 7 driver for it

I am also mining using a 64 bit compile which may have effect as 32bit made a huge difference on the official cudaminer release

Check your VRAM usage with each setup. As far as I noticed, more VRAM = faster hashrate with scrypt-jane.
Autotune gave me K13x1 which used 1694 MB VRAM, but after manually picking and testing values
I ended up with K14x1 which uses 1822 MB (out of 2GB) which is the maximum I could get cudaMiner to use without the driver crashing (note, idle memory use is 0 MB due to it being a secondary card) which resulted in slighty faster hashrates.

Now I'm reaching 2.44 kH/s with a non-Ti GTX 660.

[bigjme]

it was using 2gb out of 3gb using the files i was using. but its taking for ever to get this compiled to run a test. as i don't have copies of both i was sent one. and a new driver has just been released which has now cut my tv off while installing. lol

[cbuchner1]

there are some GTX 660 (non-Ti) with 4 GB DDR3 RAM sold in bulk for 150 Euros. 192 bit memory interface. Possibly OEM ware. 4 SMX.

This would be ideal for scrypt-jane. The only downside is that it is a dual slot card requiring an extra 6 pin power connector.

My next miner will have 4 GTX 640 and 1 GTX 660 card in it. Total of 20 GB video RAM.  Possibly hitting 12 kHash/s.

Due to the large VRAM, these cards will survive the next N-factor increase, which is due in May this year. Some 2 GB cards will run into problems then.

the latest 12 GB Tesla cards would be fun to mine with!

Christian

[bigjme]

will my 780 out last the n rise?
and 12GB? mmmmm me want one

[bathrobehero]

Try to go a bit higher to like: T16x1 or T18x1

[bigjme]

i will give it a try with the new drivers and see if it runs ok

[DBG]

so 2012 100%? and i take it that i will need to compile it all on my system with the gpu in it? cant d it on my laptop for example?

When it comes to compiling/cross-compiling, all you need are the correct libraries and some time (i.e. you could compile this on a computer that only has integrated graphics).  

POST HI-JACKING (semi-related)
I actually have a setup for nightly builds (I break things a lot when I code so I needed a continuous compiling/integration solution) and would be happy to compile/host new cudaMiner builds (the settings I have now only create a new package/packages when there has been a commit and then it waits 30 mins before queuing it).  Travis CI (which I'm not a huge fan of but it's godlike compared to Jenkins) is available to all GitHub projects and I'll probably pull the current master branch and try and come up with a working YAML file.  Then if cbuchner1 wants to use it (assuming I can nail down all the prerequisites) he can.

[bigjme]

T16x1 gives me 2.2GB memory used. hashing at 3.07khash/s

it does cause a driver crash and debug is stating "DEBUG: got new work in 0ms" and sometimes says 15ms.
so i take it that it is still running ok

[bathrobehero]

Do you mean at the beginning when you run cudaMiner that it hangs for so long that your driver crashes?
Because to me it does hang for some time, but it's not that long to trigger the driver recovery.

Anyway, after the initial hang, to me everything is perfect.

The only time I get crashes if cudaMiner states that there's not enough memory (with the current kernel configuration). If it's the same to you, you could probably go and try T20x1 and maybe even a bit higher until you're using the maximum amount of VRAM. I only have a Kepler, so I'm not entirely sure, but that is what I'd try.

[bigjme]

i run it, and just on the first hash attempt the driver crashes and recovers, then it carries on

ok so i had everything installed, can not for the life of me figure out how to clone the git so i am going to give up lol
