A brave tester with 8 Fermi cards Tesla M2090 (thanks Choseh) just figured out the performance regression between 2013-12-18 and 2014-02-02. If you change the #if 0 in the fermi_kernel.cu to #if 1 (thereby enabling the previous version of the Salsa20/8 round function) you should see the previous performance figures again. Those who can compile the code themselves and want to mine on Fermi are welcome to make this change themselves. EDIT: False alarm apparently. My tester cannot reproduce this now

also there seems to be a bug in the autotuning code in salsa_kernel.cu

                            hash_sec = (double)WU_PER_LAUNCH / tdelta;

should very likely be

                            hash_sec = (double)WU_PER_LAUNCH * repeat / tdelta;

to factor in the number of repetitions in the measurement (we want to measure for 50ms minimum for better timer accuracy). So autotune was drunk after all!

So, it seems I should release fixes (new binary release) for these problems tonight.

Christian


I've been experiencing problems with the 2-2 and 2-4 releases, both dropped my Kh/s about 20-30 on my GTX 560 Ti (Fermi). I've been using the 12-18 release to maximize my hashing power.

Here's my config:

cudaminer.exe --no-autotune -O user.worker:pass -o stratum+tcp://pool.com:3333 -C 1 -i 0 -H 1 -l F8x16


I have noticed that the newer releases report that the maximum warps as 209, whereas 12-18 shows maximum warps as 211. I did a benchmark on 2-4 with -C 1 -H 1 and -i 0 flags included, which gave me a config of F32x4. According to all of the resources I've read, F8x16 is the maximum my card can handle before giving CPU validation errors.

Quote from: Quote from Readme
Example for Litecoin Mining on coinotron pool with GTX 660 Ti

cudaminer -d gtx660ti -l K28x32 -C 2 -i 0 -o stratum+tcp://coinotron.com:3334 -O workername:password

Anyone else getting infinite "result does not validate on CPU" errors with this settings?
I have an Asus GTX 660Ti OC

I think you need to use k instead of K for 28x32, as far as I understood from christian's post. K = Y in new release. I am using K7x32 for my 660Ti non-OC.

Here is how launch configs from the cudaminer 2013-12-18 release translate to cudaminer 2014-02-02 release
to get equivalent performance. This can be handy if you find some older launch configs posted by others

 L b x w  ->                   sorry, legacy kernel was replaced by Fermi kernel. Autotune the F kernel.

 F b x w  ->  F b x w       ( no change to this one )

 K b x w  ->  k 4*b x w    (the previous K kernel is now named k and no. of blocks has to be quadrupled)

 T b x w ->  t 4*b x w     (the previous T kernel is now named t and no. of blocks has to be quadrupled)

 S b x w  ->                   Spinlock kernel is GONE.


These following kernels are new in the cudaminer 2014-02-02 release:  T (nVidia), K (nVidia), f (ported over from David Andersen's code).

Christian

Anyone been able to get a evga gtx780ti with acx cooling to 640khash?

Highest I can get is around 400.  I'm just guessing different values now.  But the old version could get very close to 650
cudaminer -a scrypt:2048 -d gtx780ti -H 1 -l t15x16 -C 2 -i 0

For vertcoin getting 181khash/sec.  The gpu reaches 1.1Ghz when running cudaminer.  I should be getting over 650.  With the old version gpu would only get up to around 1000mhz.  So now I'm getting 100 more mhz but very bad hash rates.



Have you tried dropping -C. I have genrally seen that -C 1 and -C 2 drop the hashrate.

I have been away for a while, but I'm glad people are using my and Christian's binaries for good. I'm still mining Microcoin with them. Gives me about 168 kilohashes on an OC'ed 560 Ti. It even found around two blocks since yesterday. ON towards becoming an MRC Millionaire! If anyone needs any help, feel free to get in touch.

Christian, could you please explain why the F and X and f autotuning give much much lower values and choose something else then F16x8 / F8x16 on my card? Those give me 168 kilohashes, anything else is 120-130 and autotune isn't showing those configurations to give more then 70-80 kilohashes, so another one gets chosen. I'm glad I found my "sweet spot", but others may not.

I ran autotune again in debug.  And got this
cudaminer -d gtx780ti -H 1 -l T59x4 -C 2 -i 0

This gives me what I got with the december release around 630 to 650.

Would you try 60x4 as 780ti has 15 SMX thus 15*4 = 60. Maybe it will help.

EDIT: Also should it not be t instead of T = Y kernel from nvidia.

Could you give me some advices how to finetune Kepler and Titan cards for mining low-factor scrypt-jane coins? For example with Vertcoin

VertCoin is an exception, it's not scrypt-jane, it's scrypt with an adaptive N factor.

I tried t60x4 get around 370.  and T60x4 gives me 570.
So T59x4 is the best so far.

depends. I tend to add new hashing algorithms only if there are enough coins to mine (there's more than a dozen Yacoin clones, for example).

If someone posts a reasonable bounty, I might add it faster. Or someone else takes cudaminer and adds it provided the bounty is reasonably high (it's open source, and forking it on github is easy as pie).

Anyway.... 9 more hours before the wallet and miners are released, so I cannot currently see how it is working - in particular how the PBKDF2 is applied and whether they use Keccak256 or Keccak512.

I tried t60x4 get around 370.  and T60x4 gives me 570.
So T59x4 is the best so far.

There seems to be a lot of confusion over the different kernels since the release so I just want to repost directly from the README:

Code:
Prefix Alias Compute Req. Registers use for
F L 1.0 64 scrypt & low N-factor scrypt-jane
K Y 3.0 63 scrypt & low N-factor scrypt-jane
T Z 3.5 80 scrypt & low N-factor scrypt-jane

f X 1.0 32 high N-factor scrypt-jane
k 3.0 32 high N-factor scrypt-jane
t 3.5 32 high N-factor scrypt-jane

the old "Legacy" kernel has been replaced with the F kernel, which will also be faster on Compute 1.0 legacy devices in many cases.
Therefore the F kernel has been compiled to require only Compute 1.0 capability.
      

T, K, F, t, k, and f are different kernels with different uses. Please keep this in mind when you are making suggestions to others on what kernel to use.

For those who were using interim releases (special thanks to those who provided their self compiled binaries!)
  • If you were using T, K, or X kernels for scrypt-jane , you will want to use t, k, or f respectively.
  • If you were using Z, Y for scrypt in the interim releases, you will want to use T, K not t, k.

SMX counts(source http://en.wikipedia.org/wiki/CUDA):
Code:
Compute ver. 1.0 1.1 1.2 1.3 2.0 2.1 3.0 3.5
Cores per SMX 8 8 8 8 32 48 192 192
To find the compute level of your card please review this site:
http://www.techpowerup.com/gpudb/

For scrypt using the K Kernel generally the best basic configuration is going to be K(SMX)x32, you can find the SMX number by finding the number of Cuda cores on your card and dividing by 192. For example a GTX 680 has 1536 Cuda cores this means the SMX for your card is 8 giving you a basic config of:
Code:
-l K8x32

For scrypt using the T Kernel generally the best basic configuration is going to be T(SMX)x24, you can find the SMX number by finding the number of Cuda cores on your card and dividing by 192. For example a GTX Titan has 2688 Cuda cores this means the SMX for your card is 14 giving you a basic config of:
Code:
-l T14x24
Special note here, some oddities have been noted for some makes and models of cards in this kernel and the T(SMX)x24 is not always the best, Once you have establish a baseline hash rate at T(SMX)x24 try to reduce the "warps" section (ex. T(SMX)x20 or T(SMX)x16) and see if there is improvement.

For scrypt using the F Kernel generally the best basic configuration is going to be F(SMX/2)x32, you can find the SMX number by finding the number of Cuda cores on your card and dividing by the appropriate core count for your Compute capability. For example a GTX 580 has 512 Cuda cores and is compute 2.0 this means the SMX for your card is 16 giving you a basic config of:
Code:
-l F8x32
Note: If anyone has a different observation for the Fermi cards please let me know! I have only compiled this part from observation I have no direct experience with this GPU Class and Cudaminer.


This only helps with basic Kernel selection and configuration, it is up to the individual to identify what additional -H, -C, -m, and -L parameters work best on your configuration.
