Interesting AMD miner: Claymore's Dual Ethereum+Decred GPU Miner v1.0

I wonder if the same could be done for nvidia.

I talked about this at length, many moons ago on that once popular cuda mining application thread. 
Looks like no1 from our camp decided to pick it up, but there was always some sense in combining a memory-hard algo, with a compute-hard algo, for optimal GPU usage. Great news for the AMD miners if that works out, not-so-great for us here with nvidia

And for some reason he's still making miners with dev fees... Hmmm... wonder if it's worked out for him for the last three years.

But jesus... Decred is going to get tanked. That's merge miner glory town... This makes me feel a bit sad inside. It's going to earn as much as Ethereum was worth mining last month...

Interesting AMD miner: Claymore's Dual Ethereum+Decred GPU Miner v1.0

I wonder if the same could be done for nvidia.

I like it. I've thought about something similar and played around with running two miner instances in parallel,
each one mining a different algo without much success. Depending on the algos I choose I can get a bit over 100%
but not much. Each algo hashes at a significantly reduced rate but the sum is greater than either ine alone.
Complementary algos work best, one CPU bound, the other memory bound.

I have no idea how Claymore managed to hash a second algo without reducing the performance of the first. There
seems to be a priority order with ethereum being higher.

...yeah I saw he didn't mention the speed of Decred either. I assume it's working on whatever is left over.

They expect value. When a new release comes out they expect significant performance increases
in preformance.

And when Pallas opensource a 10% improvement, they expect me to do another +10% in my mod right? And when Alexis spend another 50hours to squeeze out a few percent, they expect that the sp-mod will be faster right?
The competition is also working. You never see wolf0 release updates to his modded kernals. I do. Sometimes with bugfixes, sometimes with improved hashrate.. My Vcash and cryptonight kernals need some more work. Let's see what I can do, the limit is not yet reached.

X11:

My 1.5.74 does 14.5MHASH on the 980ti with OC

My private does around 15MHASH on the same clocks.(0.1BTC)

I am working to reach 15.5MHASH kernal in the sp-mod ultimate(simd rewrite).. Much more interesting than the stupid blake algos.. a 980ti@15.5 MHASH makes $4.6 a day on nicehash mining x11 with todays prices..


Sp-mod ultimate will contain these modded kernals:

1. x11,x13,x14,x15,x17
2. quark,nist5m
3. lyra2re,lyra2v2
4. Neoscrypt
5. Decred, Blake2s, Vcash, Pentablake

Refork of 1.7.5 with all the bugfixes and improvements by tvpruvot.

Wolf0 just AES_NI optimized a CPU miner for HOdl for a bounty and released the source. Now anyone can take that source
and improve it. He did the same with his cryptonight AES_NI optimisations. I've added both to cpumier-opt. He got his bounty
so I'm not stepping on his toes. Whether he chooses to optimise further is entirely up to him but he probably realizes the
profit/work ratio has gone way down.

That is part of the problem with SP_MOD. Early on the was excitement for Maxwell and people were anxious to donate for
more hash and the improvements came big and fast. But that has reached the pont of dimishing returns, donations dropped
off, improvement were fewer and smaller and interest waned. Your profit dropped and you tried to get them back. The
conversion from free to fee based didn't go smoothly. For one the big increases for existing algos were long gone, each
release was only 1 or 2% and sometimes caused regresssions on some cards. People don't want to pay for that. You need
to produce something people want to pay for, not something you need to beg them to pay for.

Your reaction to the inevitable has been negative and has had the effect of turning off many customers making the situation worse.

It would help if you accepted the reality that the big gains in Maxwell are done. You should focus on new algos and prepare
for Pascal and Cuda 8. If you get a head start it could give you a market advantage which means more profit for you. Imagine
being the first to advertise a Pascal optimized miner. I'm sure poeple would be willing to pay for that. Shit I just tipped off the
competition. Oh well better for customers.

Ofcourse ppl will donate for a 6% faster x11 kernal if it is profitable. With etherum and decred taking a dive, you need to move the rigs to the profit. Everyone is welcome to mine Dash. If you don't use my modded kernals you are eighter stupid or have to few cards..

People who already mine x11 will, but I don't think it will motivate people to switch to x11. That decision is probably made
based only on x11's proofitability regardless of the miner.

Another porblem for devs was cuda 7.5. It's release should have been an opportunity for further optimisations but it
was a flop. Most of the work on cuda 7.5 was to recover lost hash. There's no profit in that.

You are wrong. The big gains in Maxwell are only in private farms.

Ok, the're done in private farms then, but the're still done. If they were yours I expect you would be releasing
them in your fee based miner so I assume they are other devs' private miners. If you can't get access to them
you can't sell them so your Maxwell business is also done.

Like I said, focus on pascal & cuda 8, be the first to market with a pascal optimized miner, make lots of profit.

Worth way more than 0.1BTC. I will not do the opensource pascal mod. You can do it.

I said profit, not open source. If you have the product when people want it you make big profit. You can decide
how you want to market it and if and when you open the source. At the moment you are trying to sell a product
that has no market appeal. Develop a better product and it will sell itself.

That's what I'd do, if I could. I have cpuminer-opt, but it isn't a marketable product so there is no point in me
trying to sell it. But the work is fun so I do  it.

BTW I got my first donation a couple of days ago but I'm not sure it was for my cpuminer work.

Still waiting for it sp.... donated .4 BTC total.

Comming soon. I have already merged all the kernals in 5)

Check my donation adress again in a block explorer. My kernals are good. My donators are mostly happy. My kernals work, and they are the fastest in the world available for the small miners. The sp-mod ultimate will wrap it all up. With all algos optimized you are guaranteed a higher profit..

Decred is tanking only $1.45 now.

I can't sell even if I wanted to. My holdings are all in tickets... And I am happy with that.

I will buy Decred below 0.025 On all time low..

Interesting AMD miner: Claymore's Dual Ethereum+Decred GPU Miner v1.0

I wonder if the same could be done for nvidia.

Looks as though AMD miners aren't seeing a huge benefit from merge mining on lower end AMD GPUs. Higher end ones are giving a boost in DCR mining. I'm guessing this due to the fact that the GPU is actually being utilized and it's not completely memory locked.

Nvidia GPUs would see probably pretty close to full utilization on DCR considering they're pretty memory bound with ample GPU processing.
