2.2 released yet? or is it still in development?

2.2 has been out for awhile now; there should be a link on the first page of this thread. I can confirm that it does give ~10% boost when mining DNR. Smiley

There is no link in the first post.

THE 2.2 CCMINER VERSION IS A DEVELOPER'S SNAPSHOT--

It is not yet a pre-release on GitHub.  You will find a few links to it in the BCT threads, at least one is on Signatum (SIGT) thread.  I believe that the link on the first page of the SIGT thread for the "nVidia GPU miner" is a contribution from Epsylon3, but it does not reside on his GitHub.  Epsylon3 has published links to his preview folder in at least one BCT thread.

Seek and Ye shall find.       --scryptr

Yes, found one on another board.

But:
It is 10 % faster indeed. It shows that in the miner itself, but my average hashrate on my pool is even a bit lower than before. Dunno why.

2.2 was improved by 10% (like sgminer) with the midstate pre-computation

Where could I download v2.2 ?

THE COMPUTATION ALGORITHM IS DIFFERENT--

A miner calculates hash rate by counting the hash cycles that it performs.  The pool estimates hash rate by counting shares received.  There is also signal latency involved (ping time) in the error.

Are some pools crooked?  I think so, and avoid them.  To make your decision about any pool's hash rate accuracy, look at the reported rate over time.  At times my hash rate is reported 10% higher (on most pools) than my local rate.  So, error works both ways on an honest pool.        --scryptr

only DNR was improved, not SIGT (cf the changelog) and no, this project is made for VS2013 and linux (not VS2015 nor 2017 even if its possible to migrate it)

How to change the intensity setting? tried -i and -intensity

its "-i auto" for example



PLACE A NUMBER AFTER THE "-i"--

For example, "-i 21".  However, CCminer will crash if intensity is set too high.  Leaving it at default (no "-i" flag), or setting it to "-i auto" may be more safe.       

Different CCminer variants will take different settings for intensity.  For example, Nanashi's CCminer code works well with higher values of intensity, but other versions would crash.  Some coders set the default intensity so high that their code crashes with any extra value for intensity.

It takes experimentation to find the best value.       --scryptr

Epsylon,

Did you try Cuda 9 RC yet? Looks like __shfl was deprecated in favor of something else. There´s no programming guide for V9 yet so I don't know for sure.

I´m trying to give it a shot to see if they improved compiling for sm_61.

Almost all algos run slower on sm_61 compiled code, comparing to sm_52, which is a bit odd.

is it possible to dual mine on ccminer?

for example:

Problem no.1

Rig: 1060 & 1070

1060 mining on timetravel (bitcore)

1070 mining on tribus (denarius)

what is the code for problem no.1?

Problem no. 2

Rig: 1080ti

1080ti mining on timetravel and denarius at the same time.

what is the code for problem no. 2? is this possible?

thank you very much.

yes... sm_61 is an emulation of sm_60 P100 fp16 stuff, and when used (look like it is sometimes) its slower than normal ops generated for sm_5x ... So nothing changed for the GTX (and mining cards) about that since CUDA 8

ghostwalker: -d 0 or -d 1

So when compiling for 1080ti, you recommend using sm_60 or 61?

@scryptr - when Im using high intensity values like "25", the power limit is very unstable, but it does generate higher hashes. what is the implications of such power variances?

LOWER YOUR INTENSITY--

Stability and efficiency are just as important as maximum hash rate.  A higher, unstable hash rate is wasting wattage and time.       --scryptr
