Sorry to stir up such a shit-storm. I mean. yes, at some point one does have to look at the economies of their hobby if they want to move beyond it being just a hobby. 35MH/s mining quark from a single card sure got my attention, until I looked at the average price on ebay trending about $675 a pop. That's a very big investment for such a small return. And in 3-4 years when you've finally broken even, the card itself will have probably depreciated in value to pennies on the dollar. To really be in the game you have to be rotating out cards no more than 1 year old to get any resale value, constantly updating miner software to keep up with the flow of newer, and better cards coming out, yatta yatta yatta. I'll leave it to the kids. I'm too old already for that nonsense.

And calling it an attack I think might be overstating it just a bit. A little blunt and abrasive, maybe. I fit that description sometimes too so I try to overlook it in others. Deep breath, everyone. There. Doesn't that feel better?  

if you want to discuss code, irc is probably a better place, because you can have a "quasi" live discussion, here on the forum read by 1000 (hmm 100's ) this is not the best place as you get influenced by how you might looked in front of the crowd of potential donators (I personally don't care to be popular, which gives me the freedom to say what I think   )
on the irc where there is practically nobody, one can expect a more adult discussion without the effect of "peer pressure"

I'd come to irc, but I hate chatrooms :-)
I prefer forums with well-thought and useful posts only.

you know there is an irc channel #ccminer where you could discuss your issues with epsylon3 code, rather than writing message which can be interpreted as bashing  (if it wasn't the case...) where we (all the other dev) are usually discussing...

Something is not right in the new auto benchmark of all the algos in release 1.7.

The 980ti is mining penta slower than the 750ti.
Quark is 50% slower than sp-mod release 73
Lyra2 is as slow as the 750ti
Lyra2v2 is 43% slower than sp-mod release 73

Come on girls, get back to your own threads.

I am not. I just don't see the point in using the old slow hardware for mining.
The tpruvot 1.7 release is faster in quark, x11,x13,x15 because he has used my blake512 maxwell implementation, still it's much slower than my fork.
He just need to copy the rest of my kernals...

ok good for you... but why are you coming here to bash epsylon3 work ?

DJM34. I have published 73 (!) releases.

The latest is adding 5% in the doom algo (luffa512) 12.5% in the deep algo. and 100KHASH more in qubit. I have recieved 0BTC in donations for release 73.

I am sharing alot of my work. My kernals are the fastest always.


1.5.73(sp-MOD) is available here: (08-nov-2015)

https://github.com/sp-hash/ccminer/releases/

The sourcecode is available here:

https://github.com/sp-hash/ccminer

see ? 

Why don't you release your profitable lyra2v2 kernal then. Since you don't do this for profit, share your work...

where are all the ideal behind crypto ?
when I started to get interested in crypto (jan. 2014 so it isn't old) most people were still talking about creating a "fairer" means of exchange and so on,
programming by passion (just look at the beginning of Christian Büchner thread) because it was fun.
Now every discussion in which sp is involved is just about profit (mostly his).

and anyone who logged to #ccminer channel at least one knows that Epsylon3 isn't doing that for profit, so when sp comes to his thread to bash his current development (and there are still hobbyist with old card, who don't mine for profit) this is pretty much out of the line (like many of recent sp intervention).

the problem with sp is that he thinks the other devs (you included  ) work for him and has to make him or his release successful... 

but money is about money :-D

you know that not everything is about money ? hmm, no you don't...

This is not an attack this is just facts. A well coded 980ti kernal can mine quark easily at 35MHASH.

35x the speed of the old shitcards and with 250W of power. Instead of 5 cents a day you earn $1.75 and that's enough to cover the powerbill and give you free beers in the weekend.

ATTACKS--

Some of the attacks have been vulgar.  More than one poster has been overdoing it.

Have any of our talented coders earned a NiceHash bounty yet?

WOOF!

--scryptr

sp please go back to your thread... (your attacks are so pathetic, that it doesn't even deserve to be commented...)

Well there are plenty of "hobbiest" miners, like myself who are just playing around with older kit, who'd would be very happy with the updated software and its features

FYI on my Nvidia GT430 (Compute 2.1) on a Win7 PC, mining X11  I get 235 Kh/s (reported by the software) using ccminer21 ver 1.0 beta and 202Kh/s using ccminer 1.7-dev (so if you can tweak it a little I'd be very happy!). The video card is also running at a higher overall utilisation running the newer software while delivering the lower reported hashing rate.

Thanks for the work on ccminer.

 

With the current prices you will make $0,05775 of mining quark 24 H @ 1MHASH

Old hardware is a waste of power. Supporting the old hardware is a waste of time...

Glad to see you got it sorted out and thanks for sharing your results, even though they weren't as you hoped.

One of the side effects of optimized code is it's more specialized. Another example of an older miner being better
on older HW is neoscrypt. A new optimed neoscrypt kernel was added to 1.5.59-SP_MOD that significantly
improved performance on Maxwell but lowered kepler (780ti) performance. I'm not sure which version is
included in the TPruvot fork.

I tried analyzing the code to see where the significant differences were and made a few changes where I thought
it would affect perfomance but I couldn't find the critical code. I guess my c++ skills and cuda knowledge aren't
good enough.

I have 5 ways to fix this it, listed in increassing order of sophistication.

1. Simply use an older miner when mining neoscrypt on older HW.

2. Replace the neoscrypt source directory with an older version before compiling for 3.5.

3. I managed to put together a hack to select the appropriate neoscrypt kernel based on the architecture.
It's a run time switch meaning that both kernels need to be compiled into every SM version binary and the
appropriate kernel is chosen at run time.

4. A compile time solution would be preferable where only the appropriate neoscrypt kernel is built into each SM binary.
It seems only device code can make use of  __CUDA_ARCH__ at compile time so the differences in host code need
to be handled differently.

5. A unified kernel where only the critical code is architecture dependant.

I've done 1, 2 & 3 successfully and take a look at 4 when I get motivated. I think 5 is beyond my skill level.
I'm currenly using 1 because my 780ti is in a rig all by itself and I don't need to support multiple architectures.
I think this contributes to my lack of motivation along with age and rust. However if there is interest it might
be enough to get me out of my rocking chair and put on my old coding hat.
