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

[djm34]

@djm34
    Are you working on cryptonite/M7 miner at all? If so what are the prospects for release? It seems Wolf is probably working on something that won't be public. We have some interest in getting a GPU miner to be released, so if this is something you're planning on doing, or if I can help in some way let me know. I have opencl experience, not so much cuda.

I am working on it, but it won't be public right away either... (considering the work needed... and the fact I didn't even get a valid block at launch because I was using windows...)
Most of everything has to be rewritten to fit the blockheader and special data length and special target length...  
(and special integer type... and there is no gmp for visual studio and mpir doesn't seem to do what I want... and special nonce length...  
actually the uint512xuint512 multiplication is a detail in regard of all the other things...
however if you can explain me how to fit the result of uint512xuint512 into a uint256 that will spare me some time...

(actually the cuda part isn't the part which gives problem...)

Everybody's doing this

by the way, I can't get testnet to sync, is there a list of node for testnet ?
to be honest, I am not even sure it is worth it considering the nethashrate and what could be the speed of the gpu miner

I just hope, the blockheader won't change right after I have finished... it seems there is a new wallet and new stuff several time a day...
(it has been launched way too early)

I don't have any testnet nodes running. Maybe can start restart some. Blockheader is not going to change, there have been no changes to protocol, most of the stuff I have been pushing is to aid in trying to get pools and 3rd party miners running. Basically new RPC crap.

You can't stick product of uint512xuint512 into uin256. Also there are several hashes being multiplied, so at ripemd stage you are multiplying 160 x >2000 bits. Of course it is commutative and you can do in whatever order.

I really need some help here regarding my hashrate. I am not getting what is claimed with my 750 Tis

Cayars has very kindly proposed his help but was unable to this date to connect to my rig. Any other devs out here who would have time to help me out please?

Here is my issue. On whichever miner I use be it ccminer or nvminer I get lower hashrates than expected. For example on x11 I get ~2.300 Kh instead of the ~2.600Kh claimed. On dmd-gr I get ~7.000 Kh instead of the 7.800 Kh claimed. So one and so forth.

I am on Win 7 64x. Currently running nvMiner (v1.2U-D7b - 29-07-2014) with latest drivers 340.52. I had the same issue with previous beta drivers 340.43 and also previous miner versions, so it doesn't seem a driver related issue.

Thanks for any help.

I use ccminer compiled by crypto mining blog. it's hashrate depends a little on cpu/motherboard (pc in general) speed not only the graphics card. e.g.
@intel2core duo x11 hashrate is ca 100kh/s lower than on intel i7.
so
@intel2core it is 2500-2600 when @i7 it is >2600.

I meant how do you fit 160x2000 bits into sha256 and also your final hash is defined as a uint256.

don't know if it is cryptonight algo or what(appeared just recently after mining monero), but after some time(usually at night) my pc freeze(the screen is the one like when the computer is locked) and i can't moves mouse or use keyboard and i'm forced to reset or close the psu

paging mem was very low only 1g, maybe is that the problem, i rised to 2gb

Did you see my hashrate? it's not a few hash difference, it's well beyond that.

Devs, care to comment on this?

May-be you have some power saving option turned on...

i checked that is off(never/never), hyber.sys also is off, was working good before monero mining, or maybe just a virus(checked here and seems clean) i dunno...

Well the product is sha256'd. In miner land it's not common, but sha256 is capable of hashing arbitrary length messages. I believe the way it works is that the message is processed in 512 bit chunks. The first is much like how hashes in ccminer work, where r[] is loaded with initialization values. For the next chunk, r[] is just not initialized, and uses the output values from the previous chunk.

no, sorry  
You don't give much indication either on how you run your card. not all cards are the same perf (motherboard, # of cards, psu etc... may certainly play a role)

I might sound a bit lame, but this is funny how often we get complaints and how little we get donation...  
(I think we should charge for technical assistance, like any software company...)

That's probably the case, so I guess there will quite a few rounds

Mobo: Gigabyte GA-990FXA-UD3
RAM: 4Gb
CPU: Sempron 145
GPUs: 6 x 750 Ti plugged on powered raiser (there is no difference if I plug them directly on the mobo). 4 are Gigabyte 2 are ASUS.
PSU: 2 x 860 Platinum 80 Plus rated Seasonics. Surely I don't need the two but there are just the leftover of when I was mining with R9 280xs.

Not sure where I was complaining. I am asking a question and kindly asking for help. Was not a request. I thought donations were voluntary but the way you bring it up sounds like an obligation.

It's ok if you don't want to help.

BTW, how many GPUs?
R U using risers?
What motherboard and CPU are you using?

Any chance you could take screen shots of both GPU-Z and CPU-Z for us?

Carlo

PS the difference in our time zones makes it hard to hookup without work getting in the way.  If not before, maybe we can get this done this weekend.  I'm really curious why you run slower then everyone else.

Hello Carlo,

Yes I fully understand. No worries.

I have posted the information you asked just above. I will post screenshots in a few minutes. Do you need screenshots of all GPUs or only one would suffice?

[FortuneNVirtue]

no, sorry

My sempron (with Zotac) also performs the same hashrate  as yours.  (10% less than my PentiumG3220 (with Palit and MSI))
Let's someone confirm this.

[cayars]

Yes you sure did.  We must have been typing at the same time.  I went and got a cup of coffee and continue my post when I got back.

Cross-posted and you had already supplied the info.

Sempron 145 is most surely the issue.  This is a SINGLE CORE processor if memory serves me correctly with not a lot of cache.

I'm guessing it just has far to much work put upon it's single core with managing hardware, interrupts, windows, ccminer, etc and you are taking a speed hit.
Take into consideration you have 6 GPUs and that's one heck of a lot of work for that single core to handle.

Just for kicks, could you try running ccminer/nvminer on only 1 card to see what the speed is doing this?  (-d option)

Do you by any chance have any strong CPUs around you could switch out with it as a test?

Carlo

EDIT: FortuneNVirtue had posted while I was typing this with the same conclusion based on his first-hand experience.  I think we have found the problem.

lol, donation are still voluntary... but clearly if I had to scale the appreciation based on the donation, I would say we are doing a shitty work (might be true though...   anyhow, thanks to those who donate no matter how much they give...)

[cayars]

More of a band-aid then anythings else but:
1) go into bios and turn off any options you don't have to have turned on.  Examples would be to turn off comm ports, parallel ports, etc
2) turn off any virus detection type programs if running.
3) In networking try running only TCP/IP and no other protocols
4) make sure your machine is setup for performance and turn off any monitor dimming or hard drive speed down options.  We want machine running 100% all the time
5) close any other programs running in the background or in the task bar, including any wallets
6) stop any un-needed services from running

In a nutshell you want to try and get the machine as "lean" as you can. You might pick up a few additional hashes.

My gut says to go buy a new MB/CPU and to get at least a quad core proc. I'd pickup the highest end/fastest you can afford with 6 GPUs as you can use some cores for CPU mining.  With the additional hash you will pick up from all 6 GPUs plus having the ability to CPU mine something like XMR you can get ROI on this purchase.

But I'd still be curious to see what the hash rate is when running just one GPU.

Yea, I'd be living in a cardboard box out on the street.   But that's just how it typically is with almost all open-source software (few exceptions) and it's members who help.
