CCminer(SP-MOD) Modded GPU kernels.

[Amph]

Just had a quick look. 70% of the time is lost in the cuda_streborg.cu. I managed to remove 10% pretty quickly. Sib is x11+streborg.

so it's possible in the end to double the hash? even 4MH would be a good achieve, but would put the coin at less profit than etheruem or around that

I think it is possible.

is there any efforts to make a dual GPU miner for nvidia like claymore for dcr and eth

SP was making one then stopped. I think Genoil is contemplating it, but hasn't done it yet. No one is collaborating to make it easier.

Not sure why, it's a hot item miners are willing to pay for either in BTC or in a fee.

Dual mining is actually far from hot. Red or green.

-edit- ok it is hot with red.

Just run the decred private #9 with -i 26. Works ok on the 980ti. doesn't work on the 970

Hence why we need a actual dual miner. I tried this months ago.

You just need to remove some blocking synch code from the binary. You can do it in a hex editor

TWO SIMULTANEOUS MINERS-

I tried it, Genoil's miner running with a Decred miner.  It worked, but not well.  Genoil's miner would run in spurts with zero hash, then in spurts with full or nearly full hash rate.  The Decred miner would work at a slower hash rate.  It seemed awkward, and not really working well.  I don't know where the blocking code is to remove it, either.

As I have said in the past, I used to run 2 instances of CudaMiner simultaneously.  It worked well, like running 2 threads in CGminer or SGminer.  If one miner crashed, the other would pick up the hash rate.

Miners would pay for a well co-ordinated dual miner.       --scryptr

[bensam1231]

Yup, it's not well balanced at all. It goes back and forth. Usually you just end up worse hashrate overall.

If it's really that easy SP, it shouldn't be that hard for you to make it work properly. I can run both at the same time. Add a compatibility mode to the Dcr miner so I can run it alongside Genoils without problems.

Very Intersting , i have gtx970 , but buy 1070 very soon .

[bensam1231]

I really hope Ethereum never goes PoS because when it does GPU mining is going to completely fall apart. Eth is gaining about 1TH per month and it doesn't look like it's slowing down.

We're going to be completely fucked when it does.

[restless]

You have to realize that Nvidia chips up until Pascal, have penalty when switching contexts of computing - or between computing and gaming
afaik, Pascal does have a penalty but way smaller.
AMD chips can switch almost for free between tasks - because GCN was deveoped with such scenarios in mind...
Too bad AMD never capitalised on this, except in cryptomining... and funny thing is, they were not targeting this niche at all


So "native" dual-miner will give way better results for NV. On AMD combining 2 non-native miners is more likely to give satisfying results

IMO

ABORIGINES DANCE IN MY 970 RIG?

OK, there is voodoo magic in my nVidia rig and it makes things all better?  WTF?  What precisely are you saying here?       --scryptr

PoS doesn't really matter because there's a difficulty bomb in place so mining will get harder and harder until it's not profitable anymore:

Difficulty adjustment scheme

A lot of you have been wondering how we would implement a switch from PoW to PoS in time for Serenity. This will be handled by the newly introduced difficulty adjustment scheme, which elegantly guarantees a hard-fork point in the next 16 months.

It works as follow: starting from block 200,000 the difficulty will undergo an exponential increase which will only become noticeable in about a year. At that point (just around the release of the Serenity milestone), we’ll see a significant increase in difficulty which will start pushing the block resolution time upwards.

So, a year on, the network will continue to be useful for roughly 3-4 months, but eventually will reach an ‘Ice Age’ of sorts: the difficulty will simply be too high for anyone to find a block. This will allow us to introduce PoS, perhaps via Casper, if it proves itself.

The difficulty bomb might get changed to take longer to set in though if PoS/Serenity is not ready in time.

That AMD architecture is more friendly to "dual-mining"
Simply put, its easier to do make it work.
Hence for Nvidia, a dedicated effort to make dual miner will give better more consistent results than simply ruinning 2 different miners and playing with intensities.
And what runs on one MB+video+driver combo may not work on other

[giagge]

Ok but dual mining work on Nvidia Pascal in future ? .

That's good to know... So about a year from when that post was written... Which is ~3 months from now.

Not sure why they went with increasing difficulty instead of reducing the block reward, they're essentially the same thing. Also rather disheartening that it's logarithmic with a steep drop off instead of a linear increase in difficulty or decrease in block reward. This means the market is currently deceptive and we're quickly approaching Armageddon. It wont be long before everything explodes.

Three months and we're back to earning $.50 per 1070 per day... if that. GPU mining never had this much hash on it, even back during the boom in 2013/14. Pretty sure everything is going negative. 3TH is a lot of mining power to displace.

I really hope they reconsider their current position in light of other alt coins and substantial growth of their coin, if only changing it to a linear increase in difficulty before going PoS. A lot of miners, the market, currently depends on Ethereum. The spice must flow.

1070 should give us more life in mining the same with 480, much more, the earning with their spec would be 2.5 x so even if the diff double, we would still make more than what we are making right now

not to mention that the global diff would decrease if the overall market will tank due to etheruem going out of the scene

but in my case i might be forced to shut down the rig, and wait for better time, one thing is sure for me... i will not sell the rig no matter what will be the profit, i'll simply turn it off...

[pallas]

yeah don't sell it, a new coin may come and you need to be ready.
it happened so many times during the last 3 years that I've learnt the lesson

[Genoil]

My fork has a --cuda-schedule flag that allows changing the blocking /syncing behaviour. It may help when running it alongside ccminer.
