Hey cbuchner1, how about bout that To Do list  

>>> TODO <<<

Usability Improvements:
- better CUDA error handling and recovery from errors
- add failover support between different pools

EDIT: And no Cudamanager isn't a satisfactory failover implementation.

Cudamanager eats some of my hash rate...yeah, we need failover more than anything else.

Which I don't quite understand because it's incredibly easy to make cudaminer quit after 1 connection error after which you can just start it for the next pool. Simple .bat/.sh...

Hmmm, it's a bit of a pain, but yeah, should work :p
Have a bunch of scripts ready and just open the next one.

I'd prefer failover support integrated into the miner, say a cgminer style interface/api/features but with cudaminer under the hood.

I'm guessing we can't mine MazaCoin with cudaminer yet? Or does algo from some other coin work? Tried same settings as with MaxCoin, but no go.
Thanks for answer and thanks for awesome work on this, I'll be definitely donating as soon as I'm able.

Can't screen run a shell script that sets LD_LIBRARY_PATH so libcudart before starting cudaminer? Somehow I don't see how this incompatibility is a a real issue with cudaminer itself...

Don't have to
this is how I do

Code:

cat miner.sh
LD_LIBRARY_PATH=/usr/local/cuda/lib64 ./CudaMiner/cudaminer.......

cat screen_miner.sh
screen -dmS cudaminer miner.sh

Thank you, I decided to use your workaround


As I said, linux image is ready then:

Mazacoin is an ASIC feast...sha256, like bitcoin.

is it working in any nvidia cards or only the gtx 750 ti ?
Also what is the size of the image ?

Failover implementation would be amazing. It'll allow for instantmining new coins when you can't be in front of your computer...

I didn't check it, but it should work properly with other Nvidia cards, cause the driver is 334.21 linux 64bit:
http://www.nvidia.com/Download/driverResults.aspx/73666/en-us

I set image size 7700MB, just to fit into any kind of 8GB pendrive
after zip compresion - about 3GB

I must agree, any simplest kind of failover to a second backup pool - is imho very, very important thing for cudaminer next successes.

[ManiacMiner]

What is the maximum of GTX750 Ti in Maxcoin (keccak SHA3).

Can hit 200 mh/s max overclocked?

My 750Ti can +/- 165 mh with 2014-02-28

Default or Overclocked?

Thanks for reply.

I have 3x750Ti from Gigabyte, alls overclocked +135 and +450 memory with increased Power Target Limit in BIOS

I think I am going to stick to this roadmap, as my risers are going to arrive within the next 2 days.

also I got a submission of some basic code using NVML to read GPU fan speed and temperatures. I might squeeze in some kind of reporting (maybe side by side with the per-GPU hash rate reporting).

Hey guys, i know it doesn´t really belong in here, but this might be the last chance to get some Orgcoins!
Orgcoin is a merged-mineable scrypt coin, and it´s going up in price right now!
The net hashrate is currently still only 32Mhash/s.
You can either solomine it or join a merged-mining pool like http://manicminer.in/ or merged-mine it via p2pool.
Or just buy some over at https://cryptorush.in/index.php?p=trading&m=ORG&b=BTC

I hope I´m right about this, and I hope I helped some of you.

may-be if they had a wallet... this coin has been out for at least a month and they don't have a wallet for windows...
(not even an instruction how to compile it...) lazy dev... they deserve their 30mhash/s net hashrate after a month of existence

590khash/s scrypt for me, w/ default clock/memory settings on gtx 780.  it also remains responsive enough to play games & watch 720p video (not 1080p, hah).   drops it down to 500 or so.

My 5x 750 ti rig is giving me huge headaches. I'm running all 5 on powered risers and 6 pin connectors on a 750W RM corsair PSU. Asrock h81 btc pro mobo. 8gb RAM. Latest Nvidia drivers.

Is anyone getting huge lag/computer freezes when running multiple 750 Tis (5+) in one instance? I'm running windows 8.1 64 bit, and starting up all 5 at once freezes the PC (sometimes it's huge lag, sometimes I need to reboot, sometimes cudaminer crashes). Seems to only work with regular scrypt without freezing/crashing 100% of the time. I get 250 khs/card mining LTC at stock. I'm about to switch to Windows 7 to see if that changes anything.

If i don't use autotune, TDP usage seems to be pretty low (~850 khs for 5 cards), config: -l T5x24 -C 1 -H 0 -i 0
W/ autotune, I get low 80% TDP. 99% GPU usage.

Also any bit of OC to my cards (EVGA 750 ti ftw) seems to crash cudaminer about 10+ mins later (even "low" ones of +20 core, +200 mem). I don't know how other people seem to get huge clocks with these cards..

Any help would be greatly appreciated. Will throw 10 VTC anyone who can get me up and running stable at ~300+khs/card... Feel free to PM. Thanks!   

I suspect that the Nvidia driver for W8.1x64 has a bug because I have 6x750 Ti's and I ran into the exact same thing.

Swap over to W7x64 and use settings: -l T5x24 -H2 -i 0 -C 1 -m 1
...I haven't really seen much difference between -m1 and no flag at all.

Use the x86 version of cudaminer when doing this on W7x64.

Finally, for whatever reason, Chrome running in the background with some Flash or HTML5 app (e.g. YouTube) gives a small boost.

Now you're good to go.

I really wanted this to work on W8.1x64 as well, but I think between MSFT/Nvidia/Cudaminer status quo, we're stuck with W7x64 for more than 2 cards running simultaneously.

Interesting. I have (3) GTX 750Ti and (1) GTX 780Ti on W8.1x64 and have not seen any issues. What motherboard are you running? Maybe it's a chipset driver issue rather than video card (my Win8.1 machine is on an old Asus P6T Deluxe for the record).

For me, I did not see much stability issues until I pushed it beyond four cards. But there was definitely overhead noticed on the aggregate hash rate I was getting with four cards. I'm on Z87-Pro w/ Intel Core-i5 2670k. Latest drivers, etc.

Thanks for the responses! I'm going to try installing W7x64 tonight and I'll let you guys know from there. Also, any good vertcoin settings for these cards?

Anyone know any good working launch configs for 780's on Yacoin?

The one in the readme doesn't work, actually nothing with uppercase 'T' works, but rather lowercase 't'.

cudaminer.exe -l t128x2 -L 4 -i 0 -b 16384 --algo=scrypt-jane
bad screen response peaks at 5.7khash.s

I max out between 3.7 - 4.0 Kh/s.

How're you getting 5?

Oh man, thanks so much for this.
I've read about 150 pages looking for up-to-date info on scrypt-jane settings but still couldn't get a working one after hours of trial and error...
You wouldn't happen to have something for the 750ti and the 780ti?

For the frequency at which all this esoteric and ephemeral knowledge is being tested, published and forgotten after an update, you'd think there would be a collective bounty on a well-maintained repertoire of optimized settings for all common gpus... I wouldn't mind pitching in.

The boost clock of my card goes to 1032mhz (no overclock), factory has it at 941mhz so I guess I am a bit lucky.
Things like CPU speed really affect it if you are using -H 1, might be a part of it.
Perhaps higher -L values work for you (autotune it!), for me it didn't.

I do indeed not have settings for those cards, sorry.
Every card is a little bit different, autotune will probably give good results.
There has been a wall of settings, on some google doc, it outdates too quickly however.

I see, and what cudaminer version are you running?
