I'm having some difficulty pulling off improved numbers after building from the repository. I pulled the repository about 6 hours ago so I'm pretty sure I have the newest code to build from.

With the 12-18 build I get around 350 khash/s, and my command line is: cudaminer -r 10 -R 30 -T 30 -d 0 -H 1 -i 0 -C 2 -l K8x32

With the 01-20 build (I created on my machine using VS2012) I get about 120 khash/s, and this iteration I ran this command line: cudaminer -d 0 -H 1 -i 0 -C 2 -m 1 -l K32x32

Have you tried with -C 0 and passing -m 1 in the second case? This would mimick the behavior of the 2013-12-18 version.

Also why not use the new Y kernel submitted by nVidia recently. Autotune it and you might find that it is faster.

Thanks for the suggestions! Running -m 1 and -C 0 and -l auto ended up with these results:

Not sure why auto-tune is reaching so hard on the launch configuration calculations... last time it was 64x16, this time it's a whopping 372x3! And it's still selecting the K kernel instead of the Y kernel, but I'm guessing that's just autotune's process thinking the K kernel would be a better choice.

-----

I decided to specify the Y kernel. I tried several configurations, including Y64x16, Y64x8, Y32x32, Y16x32 and Y32x16... all of them crashed, then finally I specified Y8x32 and got this:

Setting -C 2 and omitting the -m 1 option bumps the numbers up very slightly (to around 122 khash/s). Still can't get up over 300 khash/s for some reason. Any additional thoughts would be appreciated, I'm glad to test any option(s) you can think of or recompile in some other way. Heck I'll even dive through some of the code if you have a logical way for me to debug it!

-----

I'm all for experimentation to find the optimal configuration, but I'm not sure there is an optimal configuration for the code/build I have right now that's superior to the 12-18 release from last month. The only other alternative I can come up with is I built the wrong executable (Release|x64) or I copied the wrong executable/DLLs in when performing my test(s).

-----

EDIT: I just noticed you made a commit about 30 minutes ago, so I pulled that down and compiled it as well, just in case there would be any change. Sadly the numbers above still stand even with the newest build.

Anybody interested in UltraCoin ?
A new script-jane coin which should launch today.
Do I need to do any modification to mine it or cudaminer will detect itself the Nfactor (should be one though... )

if you know starttime, min and max nfactor, use

--algo=scrypt-jane:starttime,Nfmin,Nfmax

This works for all new scrypt-jane coins if the coin creators only modified the above constants in the wallet's sourcecode.

Starttime is apparently 1388361600

So I guess it will start from N 9?

Code:

I use a cron in linux so in windows you would set up a scheduled bat file. It would need json and curl support so im unsure on how to do that in windows

Right now my yacoin wallet sends me email like this when ever I mine a new block

"Your Yacoin balance has changed!
New balance: 2535.26 (£36.34)
Old balance: 2485.8 (£35.63)
Sat, 01 Feb 2014 06:06:01"

Is there an easy way to do this in windows? By easy I mean without setting up a parser for the debug.log.

Yep its a curl request then json parse to get the value wanted. I will check it in a minute but by the looks of it the wallet can give start time, current nfactor, current n. And all using the same login data you use to start mining from the wallet

Christian, if I set up the stuff for getting nfactor from the wallet; would you like the code to do it?

Maybe it could be good to inplement into cudaminer for solomining? I will explain how the requests work aswell

if you're using C/C++ and base the network stuff on libcurl, then I could use the code.

Congrats on 10 mil. What hashrate should I expect from my 780 if your getting 3mhash/s?

My 780 (midly OC'ed) is pushing 460 kHash/s for MRC right now.

Note that cudaminer currently has problems with Nfactor changes during mining. So you will have
to restart cudaminer when that happens.

NOTE: at extremely low Nfactors, cuda is a bit inefficient. I noticed this with MRC at N=256 (Nfactor 7). Too many memory transfers over PCI express. Keccak hashing on the GPU still not quite as fast as I would like it to be.

So I could even do something like mine using a set coin so they have the same value in each wallet. Theres lots of different ways I think

The profit calculator would be the hardest part.
The way I would run the nfactor part would be to run both wallets. Then using my bash data request I would call the current nfactor and have the scrypt manipulate it. Running every minute to see if cudaminer is running or not

there's another difficulty: if you don't trade your coins immediately, any profitability computation based on the current exchange rate is moot. The rate may have dropped before you had the opportunity to sell Wink

IMHO a good idea is to do a round robin mining of the two coins, and then sell each one whenever there is a good short term opportunity. Otherwise hoard it. If one of the stashes grows too big, then reduce the amount of mining for that coin a bit.

BTW I've got my 10 million MRC.

just received 4 GT435 OEM bulk cards. Gotta try these.

Hello everybody,

I would like to test the Z kernel on my GTX 560 ti but i don't really want to download every dependances and visual studio. Does anybody have a compiled version on an ftp for windows of the last beta version?

Cbuchner1, any chance you'll be adding the necessary support to use Cudaminer on Betarigs: https://bitcointalksearch.org/topic/ann-betarigscom-cryptocurrency-cloud-mining-thousands-of-rigs-available-434464?

Would be great to be able to use Cudaminer for this!

I think improvements to stratum and getwork should go upstream into the cpuminer project from where I inherited all this code.

Or maybe it has been improved already? I have to check if there have been any recent commits to pooler's cpuminer...

EDIT: nope, no real startup improvements so far. Just minor fixes.

Yeh I just noticed that. 15m is 0.25btc now
I think I will switch, get a few million then see how it goes. May have to write myself a batch program and try to figure out how to do a profit calculator. Self switching cudaminer :-p

the difficulty with switching different N factor coins is that you need different kernel launch configs for every N factor. An external script could take care of this, assuming it knows he current N factor of various coins

the --time-limit feature could be used to abort cudaminer after 15 minutes to assess if a different coin is then more profitable.

Someone published a GUI for cudaminer called CUDA Manager. It's probably meant for the 2013-12-18 version at the moment. You guys should try it.

I entertained the idea of learning how to change cudaMiner to have a fixed console header where it would store some figures similarly to cgminer, without scrolling, but I quickly gave up on the idea as I have very little free time.

I'm loving the --time-limit feature!
