SOLO-MINING BUG--

Thanks for the information.  Which coin did you attempt to mine, and what hash rate did you send into the net?

I will wait for another patch before I mine on the SecureCoin (SRC) net.

--scryptr

I'm sad that it doesn't work but happy that it's not my fault
:-D
I assume we can revert the last commit, than, because it disabled the "don't send work to GPU while disconnected", which is quite useful.
Actually I just wanted someone to test it (to know if that part was to blame), not that it ended in the main fork...
I'd have tested it myself if I had the time to do it.

Git 1092 dont work whith solo mining...

SECURECOIN--

I have downloaded the latest SecureCoin (SRC) wallet, version 0.9.0.0-g12be17d-beta.  It is now called "Securechain-wallet", and contains security upgrades to protect from the Heartbleed bug and etc.  It is synchronizing as I type this, and fairly quickly.

I plan to solomine SRC and test the latest git from sp_, commit 1092 with Pallas' patch.  My 6x 750ti FTW rig can generate 40Mh/s+ of Quark algo in the SRC net, and should hit about 1 block per hour.  SRC is worth about 1/2 of a Vertcoin (VTC).  Right now, CoinWarz rates SRC as more profitable than VTC.  The rapid rate for finding an SRC block should at least check the latest patch quickly.

Every small change I do might not do any difference, but when you add all the small changes they matter. The changes in blake,bmw,cubehash was so small compared to the lyra2v2 algo that it was almost not messurable, but my implementation use less assembly instructions. After I changed the lyra2v2 algo to use less registers my version is mining at around 4,4MHASH on the 750ti on standard clocks. I can overclock stable to 5,150.

Your version does 3,950.  (750ti) (4,6 with overclocking.) My modded kernal is 10% faster...

I do the tests in windows(x86)
You need to merge all the modded kernals together and adjust/increase the intensity to get the speedup...

I have no problem with you optimizing my work, as long as an actual optimization takes place which hasn't always been the case lately (I tested what you did on lyra2rev2 side algorithms (blake,bmw,cubehash) and I found absolutely no difference while the numbers you reported were by itself equivalent to half what you would get if you had removed these algos (minus cubehash...), which from my stand point  is more or less equivalent as saying that what I release isn't optimized. So at least make sure it is true before saying it... (especially when you say it almost every days... hey I understand that you need to motivate donators, but please don't do it repeatedly on my back  )

ps: I don't deny that you did a good job with quark and x11

I have added it now.

between those commits there is my little modification to stop gpus when disconnected (it has been edited by sp back then):

/* prevent gpu scans before a job is received */
if ((have_stratum && work.data[0] == 0 || network_fail_flag) && !opt_benchmark)
{
   sleep(1);
   continue;   
}

Let's see if it has something to do with solo mining problems; try changing it like this:

if (have_stratum && work.data[0] == 0 && !opt_benchmark)

i mostly mine quark or lyra2v2 and nothing is broken but i guess you optimized your miner or increased default intensity to a point where my cards started throttling. I am just saying that default intensity should be such that anyone  who runs the miner gets it running w/o throttling/crashing. Anyone who is not a noob can find best for their own cards for sure but it breaks or at least makes experience worse for noobs. May be set the intensity by putting your cards on reference clock from nvidia & post results from both default intensity as well as your personal highest hashrate using highest intensity you can get. This will define a range for intensity within which people can find best for their own setup. I hope this makes sense.

Here are the changeset's between release 56 and 57:
Wich algo are you mining?
The only change in the miner logic except the cuda kernals is the "stop mining when disconnecting fix" by Pallas


https://github.com/sp-hash/ccminer/commits/windows?page=7

but relatively djm34's miner is still faster in same environment. You got your variables wrong. I think you should lower intensity to a decent base, as you have done with new release. People can always try up from a lower bound and find best for their own hardware. Highest intesity for your h/w breaks the miner for people like me. You using highest intensity, now that says something about your motivations & preferences.

EDIT: i would like to add that i appreciate your work & donate whenever i can but after release 56 i had to stop using your miner. I hope we all get this sorted, i am currently using djm34's miner even though it not most optimized but it most stable for me.

Your card is trottleing, and I have already told you what to do about it.
I have reduced the default intensity abit in release 68. Please try it out.

ahem...

And after you open source it, somebody works for free and optimize your work and get a few beers in donations. I don't understand your problem.. Miners needs the software to be up do date to earn money. Old kernals are not profitable any more.

I think this discussion is worthless.

There is tpruvot fork from which most of the others were forked from.

It's the best one in terms of features but it doesn't have all the optimisations.
You can use it.

OR

Use sp fork if you want the speed.
Or Klaust's fork. Or Djm34's. Or make your own (tip: take tpruvot and apply the optimisations). Or help fixing the bugs.

Whatever you want to do, stop whining and go ahead :-D

BTW there will never be fair rewards for the miners because you can't measure the value of each one's work. And anyway it's a handful of dollars worth.

first: I don't release anything ? seriously ?  
I have released most of the algo which were released this year:  lyra (both versions, several optimizations and rewrite and for both nvidia and amd) neoscrypt and several others algos.  

second: stop accusing other devs. to release private miners all the time, which is your excuse for everything
(you know very well it isn't true at least for me since you contacted me to have my private neoscrypt and I told you no.
I release only very rarely private miners and mostly on a trust basis (if the fee is large enough, I could trust you more... yeah well...  ))

Have you considered that releasing something so that donation go to someone else or worst, as you just showed, that people like you don't even know I did release it, is at best irritating ?
It isn't a question of profit, donation never represented a lot, it is just a question of fairness and having his work acknowledged...  and again, I am usually paid for what I develop and open-source...

and sorry for being a bit direct... but I am saying out loud what many have been thinking for quite a while...
and seriously the only thing we ask is that the release process gets a little more serious than what happened over the past few months... where broken releases alternate with roll-back fixing in part the change which causes the release for being broken in the first place...

last: solo mining is important for many and there is no reason for it to get ignored.

To bensam1231, yeah that's right, solo miners is a small percent but if software has a bug it must be fixed i guess.

of course. don't have any other ways to check power consumption of my card

Without downplaying what sp_ has bring to us, the nvidia maxwell "small" miners communauty, he has built on top of what others like djm, truvot, tsiv,and before KlausT cbuchner had already built. Without them ccminer wouldn't be what it is.
On the other hand solomining is important for small miners : this allow us to benefit from recently launched coins or low profiles ones, often more profitable. Moreover, ethereum (rather shift, exp which have lower difficulties) mining is more profitable in solo, due to very fast blocks which penalized pools mining if you have not low latency network between your rig and the pool.
 

Considering DJM doesn't release anything, he doesn't really offer an alternative. I'd rather take a buggy and sometimes glitchy version with speed over one that's getting steamrolled by the private miners (usually released by the same person).

Also, everyone is getting their panties in a knot about solo mining. Who even solo mines now days? Only people who do have to have a relatively large farm for that to actually work (on the profitable coins). Perhaps consider charging them for a solo mining version. The amount of shits I have for this issue are about 0 as it is I'm sure for the majority of miners as we're all on pools... because, you know, we can't magic 5% of the network hashrate out of our asses.

Seems as though people are on SP's balls because profits are tight and he's offering a open source-public miner, which hurts the private miner business. For instance, DJM's toted L2V2 rewrite isn't even worthwhile anymore compared to Quark or other alternatives.
