grs-sgminer is a OpenCL optimized miner for coins using Groestl and MyriadGroestl algo (Groestlcoin, Diamond, Myriadcoin, Saffroncoin, etc).
Notice: cryptohunger.com:81 and grs-sgminer are going to be retired on 31 October 2014. Please migrate to boostpool.com before 30 September See details here.Note: boostpool.com with auto payouts in BTC and GRS is currently in Beta (official release date: 22 September). No exchange fee until 22 September and BTC payouts are allowed (just use your BTC address to log in instead of GRS address). Details: boostpool.com BoostPool now has a separate
BTC talk page.
Speed with Groestl mining:
R9 290 - 20.5 MH/s (14.4MH/s if using standard sph-sgminer with 14.6 beta AMD drivers and 9.5MH/s on drivers prior to 14.6)
R9 270X - 10 MH/s
R9 280X - 16 MH/s (some only report 12MH/s, see details below. Probably you need 13.12 driver)
Speed with Myriad-Groestl (Myriadcoin, Saffroncoin, Futurecoin) mining:
R9 290 - 34.2 MH/s

*
Windows build* switch between Groestlcoin and Myriadcoin-groestl on the fly without restarding the miner
* 5% more hashrate in optimized kernel
Version 1.3.1 (10 July 2014)
* Added support for a wide range of AMD videocards (more .bop files in the package)
* packed with 7zip now (
http://http://www.7-zip.org/)
Version 1.3.0 (7 July 2014)
* Added myriadcoin groestl support (see example-myriad.conf)
* Removed "l4" suffix from .bop filenames
Version 1.2.5 (25 June 2014)
* Added R9 290 optimized Kernel for Tahiti, Pitcairn and Hawaii GPUs
* Shows a warning if "optimized" kernel is used with incorrect pool
*
BAMT setup instructions (see step "6a").
*** Example command line ***Groestlcoin (20.5 MH/s on R9 290): sgminer.exe -k optimized -o stratum+tcp://cryptohunger.com:50001 -u FnzMEE2fkX31J5EjheNMo8pq2672Q5kjGh -p xxx -I 22 -w 256
Myriadcoin (34.2 MH/s on R9 290): sgminer.exe -k myriadcoin-optimized -o stratum+tcp://cryptohunger.com:60001 -u MUbwYW4NmmkR4Ejg5v7tQye5DW5jSQVz3X -p xxx -I 22 -w 256
Diamondcoin (20.5 MH/s on R9 290): sgminer.exe -k optimized -o stratum+tcp://cryptohunger.com:50002 -u dSwcxqXiYrZehaiy6sKfQv1NyEtxTXrmrz -p xxx -I 22 -w 256 --normal-hashing true
*** Release highlights **** Built-in Diamondcoin support (via a "normal-hashing" per-pool parameter, see example.conf)
* Automatically sets proper difficulty multiplier (not required to write --difficulty-multiplier 0.0039062500 anymore)
*
thread-concurrency and
lookup-gap parameters are not used anymore
* Added "optimized" kernel, see below
Attention
Diamondcoin miners:
* You need to specify
--normal-hashing true parameter on the command line
or in the .conf file (see example.conf)
!!! Optimized kernel binaries (about 5%-25% better hashrate than if you don't use them) !!!You need to use "-k optimized" instead of "-k groestlcoin" in command line parameters.
Note: "optimized" kernel
only works with these stratums:

They do
not work with any other pools. They do not work with cryptohunger.com:3333 either. You'll get HW errors and no accepted shares.
See statistics here:
http://cryptohunger.com:81. Payouts every hour. Just use your wallet as login.

https://docs.google.com/spreadsheets/d/1hTOUdJZrKqrNDXTIbXgNvJtj_fnpECREcs-eHxaGrZc/edit?usp=sharing to fill in your "Groestl" parameters.
Note: With Groestl and Myriad Groestl algorithms, you usually can overclock GPU quite significally. For example, I'm using 1170Mhz on R9 290 (where standard frequency is 1000Mhz).
This happens because these algorithms don't use power hungry memory exchange operations and thus GPU produces less heat and stays within TDP bounds.
Make sure you are using 14.6 AMD drivers for R9 290 and R9 270X. And make sure your are using 13.12 drivers for R9 280X (other driver versions give lower hashrate).
Note: you can compile .bin files in with one version of drivers and execute miner while another version is installed.
Notice: OpenCL source code for optimized groestl kernel is
not open source.
I am ready to exclusively sell the source code and the cryptohunger.com pool for 10 BTC (opensource or keep to yourself the kernel; use the pool or close it and be the only one using the optimized kernel).
