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

[jots]

I see people asking for pool fallback a bunch... Maybe someone else will find this useful.   *shrug*

Code:

#!/usr/bin/env bash

pools=(
    "--url=stratum+tcp://mine.Hashbros.co.in:3333 --userpass=worker.name:x --retries=3 --algo=scrypt -l Y7x32 -C 1 -i 0 -m 0 -H 1"
    "--url=stratum+tcp://middlecoin.com:3333 --userpass=15wcm1ZxixUjjq3tKEoKT55qLttoCN2TBY:x --retries=3 --time-limit=3600 --algo=scrypt -l Y7x32 -C 1 -i 0 -m 0 -H 1"
)

while true; do
    for i in $(seq 0 $((${#pools[*]} - 1))); do
        ./cudaminer ${pools[$i]}
        echo "Restarting in 3... CTRL-C to stop."; sleep 3
    done
done

In English:  Mine on hashbros until there's a connection issue.  At that point, switch to middlecoin for an hour.  Repeat ad nauseam.

Am i Supposed to have a username christian on my computer?

config  -a scrypt-jane:Yacoin -H 0 -d 2 -i 0 -C 2 -l K8x32

What i am seeing?
im trying this on a system with 3 gtx 770's

Switch from K to k.

I still unfortunately get the same errors.

***update the -H 0 Tag is a issue changed to -H 2 and not my gpu results are not validating on cpu.

now using -a scrypt-jane:Yacoin -H 2 -d 2 -i 0 -C 1 -l k8x32

Christian, I don't know how, but this release gave me such a performance boost!
GTX 660TI mining ultracoin on scrypt jane previously gave me around 280 kh/s

Downloading the new version, changing NOTHING in the launch settings, gave me this:



Settings i use:
cudaminer --algo=scrypt-jane:UTC -l Y7x28 -H 2 -i 10 -C 0 -m 1

Hi Christian,

I looked over the internet and it seems there is a more precise set of functions to get the time in windows (precision of the order of the microsecond)
Using the fonctions QueryPerformanceFrequency(), QueryPerformanceCounter().

Here an example of how it is used: http://stackoverflow.com/questions/1739259/how-to-use-queryperformancecounter

Hi,

Is it stable version win 2/2? Can I update my GUIMiner script fork with this build?

I need to push out a hotfix for incorrect default kernel selection tonight. The code on github already has this fixed now.

None of this is in units of seconds I think and changes in CPU frequency (dynamic clocking) might also affect these counters.
This is why I haven't touched them yet.

config  -a scrypt-jane:Yacoin -H 0 -d 2 -i 0 -C 2 -l K8x32

Switch from K to k.

I still unfortunately get the same errors.

now using -a scrypt-jane:Yacoin -H 2 -d 2 -i 0 -C 1 -l k8x32

k8x32 might require more memory cudaminer can allocate (in one piece).
Does -C 0 fix it?

Otherwise try using a lookup gap. -L 2 or -L 3 ... this reduces memory requirements.

and autotune with -l k  after changing the lookup gap.

Also just ran a couple autotunes and pretty sure autotune is drunk and needs to go home...

I really shouldn't have gone to that pub...

That's where QueryPerformanceFrequency comes in, to get to seconds (or miliseconds).
It's quite a common approach for high precision timing, afaik it handles dynamic clock changes just fine.

I haven't found it misbehaving in all the projects I've used it in at least.

Hi all tried new version with old settings and went from 262(12-18-2013 x64) to 288-290(02-02-2014 x64). This on Asus 660Ti with reference clocks.

Temp is 75-76C with 46% fan (ambient temp 32-33C)

X64 works better for me, tried -C 1 and -C 2 but they lowered the hashrate. My config is

cudaminer.exe -H 2 -m 1 -i 0 -l K7x32 -o stratum+tcp://asia.middlecoin.com:3333 -O 1AqywTTPox5W8Vk15JbPMfkXvXXCAztxxQ:123

Autotune is all wonky so I'll wait till christian is working on it. Thanks so much cbuchner1 for this. You da man.

Oh, for me the MRC mining became a lot slower and dropped from 270 kHash/s to 224 kHash/s
on my 660 Ti DirectCU2 from Asus.

Ultracoin also has low N-factor like MRC. So why are you getting a boost and I am getting a slowdown?

EDIT: I had /usr/local/cuda pointing to /usr/local/cuda-5.0. D'oh!  I remain in the 270-280 kHash/s
range when running interactive mode. So I am not seeing your speed boost.

Why are you using -i 10 and not -i 1 ?

Christian

[ilostcoins]

Thanks for the latest release. My 650ti can mine YACoin now. 

My 650Ti only has 1 GB DDR5 RAM and is in a Windows XP PC with only 1 GB system RAM. Autotune seems to have chosen k35x3 for it to give about 1.45kh/s at lookup gap 4. I guess that's about the expected range for a card like this.

Yeah a 660Ti would produce more than twice that hash rate. You get what you pay for

I have tried all combinations now (each on for approx. 5 mins) I get 288-292 khash/s with my 660ti. My config is

cudaminer.exe -H 2 -m 1 -i 0 -l K7x32 -o stratum+tcp://asia.middlecoin.com:3333 -O 1AqywTTPox5W8Vk15JbPMfkXvXXCAztxxQ:123

[atp1916]

Very impressive.  Perhaps this will take pressure off the top-end AMD cards.

[cbuchner1]

I have tried all combinations now (each on for approx. 5 mins) I get 288-292 khash/s with my 660ti. My config is

cudaminer.exe -H 2 -m 1 -i 0 -l K7x32 -o stratum+tcp://asia.middlecoin.com:3333 -O 1AqywTTPox5W8Vk15JbPMfkXvXXCAztxxQ:123

-C 1 should help a bit...

[Echostorm]

On my GeForce GTX 660 Ti, I used to get around 245 or so and now I'm pushing around 270.
My config is cudaminer.exe -H 1 -m 1 -i 0 -l K7x32
I tried H2 but it shaved off about 10 k/h

I also tried C 1 and though it added about 9 kh it felt like it was pushing the card too hard.  I can already hear the fans spinning up where before they were inaudible which makes sense but might be something I'll have to ease into and get more detailed temp reading about.

Thanks much bud, you're doing great work.

-C 1 adds 1-2 khash/s atmost.

I'm having the exact same card as you (but overclocked). I have no clue why you have a slowdown, and i get a boost :O
Also that -i 10 was a typo in my config, but too lazy to change, but it does not give a difference.

What if you try mining ultracoin, do you still only get 224 khash/s? These are my OC settings if someone is interested:
