Here it is finally: https://github.com/ghostlander/cudaminer-neoscrypt

It supports all NVIDIA GPUs with compute capability 5.0 and higher, i.e of the Maxwell and Pascal architectures. Should work on Volta, too, with manual settings. I’ve changed the name back to CUDAminer because both Christians who have managed the CCminer project back in 2014 are no longer in business, so the old name is rather confusing.

Both Stratum and GetWork should work fine. No GetBlockTemplate.

There is a single CUDA kernel written in PTX asm for the most part. CUDA 6.5 seems to do the best, CUDA 7.5 is slightly slower, CUDA 8.0 is considerably slower. Although there are 3 hashing modes which fit different GPUs:

-m 1 is for the Maxwell architecture. Derived from NSGminer. Does very well on 750 Ti like 270KH/s @ 1400MHz core / 3200MHz memory;

-m 2 is for the Pascal architecture with GDDR5, i.e. 1060 and 1070. Over 1.1MH/s on a reference 1070 with no overclocking;

-m 3 is for the Pascal architecture with GDDR5X, i.e. 1080. From TPruvot’s miner. Needs more work though. 1080 is almost as fast as 1070 with it.

The miner is open source, no dev fees or anything, though your donations are welcome.

const int nForkThree = 204639;

int64 GetBlockValue(int nHeight, int64 nFees) {

int64 nSubsidy = 200 * COIN;

if(nHeight >= nForkThree || (fTestNet))
	nSubsidy = 80 * COIN;

// Halving subsidy happens every 2,100,000 blocks. The code below takes account for the
// fact that the first 204,639 blocks took 2.5 minutes and after changed to 1 minute.
nSubsidy >>= (nHeight + 306960) / 2100000;

return nSubsidy + nFees;

}

and 328,125 additional

Total is 335,999,760 coins.

Everything works as expected.

NSGminer v0.9.4 Xmas Edition is ready. Hope you like it.

If the Omni developers are interested, I’m ready to co-operate. We can do what BTC or LTC don’t want to.

@alkaline18 FTC hasn’t got much done about marketing, that’s true. There are many coins out there with clueless devs and copy-paste tech, but they do rather well thanks to aggressive marketing approach. Although I wouldn’t mind if FTC gets more outreach indeed.

I don’t do Skype, but we can have a Google hangout set up for a discussion.

@alkaline18 The features you’re suggesting require a hard fork and a lot of preparation time. It’s unclear if most of the community will follow. A sizable part of the community left in 2014 after the introduction of NeoScrypt which they thought was a bad move. Time told it wasn’t, but major changes were never easy.

What ideas have you got to push FTC to top 30?

@sradics said in Is there still any activity for Feathercoin:

It has been at least in my impression really silent in this forum for the last months/weeks. Is there any activity for further FTC development planned or is the coin just there and slowly but surely dying? I also cannot find activity at https://bitcointalk.org/index.php?topic=178286.2400 .

What are in in your opinion reasons to further consider FTC as a valuable altcoin?

Are developers still on board?

They still are, though some people left on the way here, some joined.

AFAIR Myriad struggled to keep all 5 algorithms balanced and set SHA-256d and Scrypt to merge mining eventually.

FTC makes use of BLAKE2s already as a part of NeoScrypt. If I wanted it a simple way, I could just use BLAKE2s two years ago. However it isn’t ASIC resistant. Neither Groestl nor Keccak.

I get ~730KH/s on a GTX 1060 6Gb @ 90W with my CUDAminer. Additional ~100KH/s with the default 120W power consumption which boosts SPs from ~1600MHz to ~2000MHz.

@j1732 Have you specified --net feathercoin?

strip -s feathercoind

@clickinorka You can go for it indeed. Seems expensive though.

@clickinorka Older 8Gb Pro Duo cards are Fiji based. Essentially dual R9 Fury X.

1080’s don’t do very well with NeoScrypt because of GDDR5X. Access latency is too high compared to GDDR5. That Pro Duo is two Polaris GPUs with double memory on the same card. Not any better than two RX580 + much more noise.

Uploaded NeoScrypt CUDAminer v1.0.1. It supports Kepler (GK110) in addition to Maxwells and Pascals. The original Titan, Titan Black, Titan Z, GTX 780 Ti and GTX 780. Keplers were never energy efficient, so the hash rate is about 400KH/s for 200W TDP. Well, it works at least.

@bushstar said in Solo Mining:

0.8 cannot be used to mine blocks as it generates version 2 blocks which are no longer accepted by the network.

It’s a one line change to generate whatever version blocks.

main.h:1299: static const int CURRENT_VERSION=2;

You can probably still use v0.8 for solo mining as it is known to work with both GW and GBT.

GetWork seems obsolete in Bitcoin Core and derivatives. You have to use GetBlockTemplate instead. You can specify your own coin base or use one provided by the daemon.
