1  Alternate cryptocurrencies / Mining (Altcoins) / New OpenCL Kernel for Myriad-Groestl (DGB, MYR, etc.) on: October 17, 2015, 08:39:03 PM
I release open source my Myriad-Groestl OpenCL kernel which is faster than any public kernel including one bundled with the current SGminer. There is a 10% performance improvement at least. Tested fine on Linux and Windows. Supports work sizes of 64, 128 and 256.

4  Alternate cryptocurrencies / Mining (Altcoins) / NSGminer v0.9.4: The Fastest NeoScrypt GPU Miner on: July 27, 2014, 03:43:54 PM

NeoScrypt




NeoScrypt is the next generation proof-of-work algorithm designed to replace Scrypt. It consumes less memory than the latter yet is more memory intensive and stronger cryptographically. Combines power of Salsa20/20, ChaCha20/20, BLAKE2s and FastKDF into a secure ASIC resistant solution. It isn't some kind of Scrypt-Jane or Scrypt-N or whatever.


NeoScrypt, a Strong Memory Intensive Key Derivation Function (white paper)

NeoScrypt - the latest proof of work algorithm (press release)

NeoScrypt (source code)


NSGminer v0.9.4:

GitHub (source code)

32-bit Windows release

64-bit Windows release

NSGminer is an advanced NeoScrypt CPU and GPU miner with the OpenCL support delivering the best hash rates for the AMD Radeon hardware (HD4000 series and newer). Should be compatible with the latest AMD Catalyst drivers. Also provides limited support for all NVIDIA OpenCL capable GeForce, Quadro and Tesla hardware. No external dependencies other than libcurl. Getwork, GetBlockTemplate and Stratum protocols are supported.

Example configuration for the AMD HD5870:

Code:
nsgminer -k neoscrypt_vliwp -g 1 -w 128 -I 13 --gpu-engine 850 --gpu-memclock 1200 -o stratum+tcp://some_pool:some_port -O some_user:some_password

Example configuration for the AMD R9 280X (HD7970):

Code:
nsgminer -k neoscrypt -g 1 -w 64 -I 16 --gpu-engine 1000 --gpu-memclock 1500 -o stratum+tcp://some_pool:some_port -O some_user:some_password

Example configuration for the NVIDIA GTX 1080:

Code:
nsgminer -k neoscrypt -g 1 -w 64 -I 15 -o stratum+tcp://some_pool:some_port -O some_user:some_password

--thread-concurrency, --shaders, --vectors are not used for NeoScrypt. --intensity or -I is the primary performance optimiser. May be set between 8 and 20 according to your video card's memory size. For example, -I 16 means (2 ^ 16) GPU threads each of 32768 bytes = 2,147,483,648 bytes or 2Gb. There are some configuration tweaks available in neoscrypt.cl which might deliver a little bit of additional performance. For example, FASTKDF_COMPACT 1 may yield a bit more performance on the AMD Tahiti and Hawaii based cards.


NeoScrypt CUDAminer v1.0.1:

Windows builds (32-bit and 64-bit, CUDA 6.5)

Supports the NVIDIA Kepler (GK110), Maxwell and Pascal architecture GPUs only.


NeoScrypt CPUminer:

v2.4.3 for Windows (32-bit and 64-bit)
v2.4.3 for MacOS X (32-bit and 64-bit)
v2.4.3 for Linux (32-bit and 64-bit)


Implemented in Phoenixcoin v0.6.6.0 initially and hard forked at block #400K (13th of August 2014). Phoenixcoin testnet runs with NeoScrypt since the 17th of July 2014. Feathercoin switched to NeoScrypt when the 1st GPU miner and pool software became available (block #432K, 26th of October 2014). Many other coins followed (List of NeoScrypt Powered Coins). Updates will be posted to this thread.

Phoenixcoin Development Fund





In order to advance the development of Phoenixcoin and associated projects, our core team has decided to establish this development fund.

As you may know already, the PXC pre-mine has been stolen and sold at Cryptsy by the previous developer in June and July of 2013
(Phoenixcoin Wiki)

After taking over the development, most Phoenixcoin related activities have been funded by the core team members.

Phoenixcoin is a community driven coin, so if you are interested in making it a success, please consider a donation.

All incoming and outgoing funds are accounted with a public ledger.
These funds are not to be used for personal needs of the core team members.
They shall be used to expand the development of Phoenixcoin in particular and crypto related projects in general.
The current objective is to establish our crypto gambling infrastructure as well as to assist independent crypto game developers.

The donations to be made in PXC to the address below. Thank you.

7  Alternate cryptocurrencies / Altcoin Discussion / [PXC] Phoenixcoin Give-Away! 1 PXC Each or More! on: December 23, 2013, 01:43:28 AM




Another Phoenixcoin Give-Away!


Phoenixcoin (PXC) is a decentralised open source digital currency.
It was founded as a further development of Litecoin 7 months ago.
No matter what people say, this coin is here to stay.

If you want some PXC for free, you have it here!
New to PXC? Visit Phoenixcoin.org and download a wallet of your choice.
Install, launch, copy your PXC address from the 'Receive coins' tab and paste it in this thread.
Would be nice if you care to say what you think about Phoenixcoin, too.


The conditions:

1) anyone with at least 10 forum posts can participate;

2) only 1 payout per user (nicknames and addresses are logged);

3) regular payout is 1 PXC;

4) you get double the regular payout if you've ever mined to the address you provide
(we shall verify with a block explorer, but you tell us first).


You can spend the coins on dice games at Altcoin Dice, blackjack at Crypto Blackjack or whatever else.

The coins are given away in small batches to minimise time consumed and transaction fees, so be patient.

9  Alternate cryptocurrencies / Altcoin Discussion / [ANN] [PXC] Development Takeover on: October 01, 2013, 04:53:19 AM

Phoenixcoin






As it become apparent that the previous PXC developer, Mike Burns aka iamatrix, abandoned the project,
also took the primary web site and forum down nearly 3 weeks ago without any prior notice,
and his competence in cryptocoin development leaves much to be desired in general,
I have decided to take over the coding to bring the coin back in business.


I have fixed two critical vulnerabilities in this 0.6.4.12 release:

1) broken IRC peer discovery which in fact didn't allow new peers to connect to the network
(now works fine using any of three LFNet nodes coded in);

2) communication issue when PXC peers accepted connections from non-PXC nodes
(it was driving Qt client crazy showing progress like 300000 blocks to download).

Further changes require a hard fork to be introduced in a few weeks after research and community discussion.


[ANN] [PXC] Phoenixcoin v0.6.5.0 Released, UPGRADE REQUIRED Before Block #154000


Our new web site, Phoenixcoin.org, is online.

Any development related matters to be discussed at our forum hosted at CryptocoinTalk.

I have no insider access to PhenixEx or other half baked projects of the previous developer, so don't bother to ask me about them.
