about bamt -> http://bamt.wikia.com/wiki/Litecoin_BAMT

on bamt system

apt-get install libcurl4-openssl-dev pkg-config libtool libncurses5-dev
apt-get update
cd /opt/miners
git clone https://github.com/sgminer-dev/sgminer.git
cd sgminer

CFLAGS="-O2 -Wall -march=native -std=gnu99" ./configure
make

cd ..
mv sgminer sgminer-5.1.1-lyra2re

cd /opt/bamt
vi common.pl
modify the sgminer-sph section to sgminer-lyra2re using the path /opt/miners/sgminer-5.1.1-lyra2re

cd /etc/bamt
vi bamt.conf
modify the cgminer section by adding a line with sgminer-lyra2re.conf and miner-sgminer-lyra2re: 1

copy sgminer-sph.conf to sgminer-lyra2re.conf and fit the values for your graphic card

i am currently running a sapphire 5850 xtreme with i=18, clock=775, mem=1000, volt=1.000 with about 350kh/s @ 170Watt @ 68°C

good luck !

Updated the donation text in the OP:

If you feel you can donate to: 1H7qC5uHuGX2d5s9Kuw3k7Wm7xMQzL16SN
Or just mine a bit with the provided start.bat which loads the included lyra2re.conf:
{
"pools" : [
        {
                "name" : "NiceHash_Lyra2RE",
                "url" : "stratum+tcp://lyra2re.eu.nicehash.com:3342",
                "user" : "",
                "pass" : "d=1",
                "algorithm" : "Lyra2RE",
                "intensity" : "15",
                "gpu-engine" : "835",
                "gpu-memclock" : "1500",
                "worksize" : "128",
                "gpu-threads" : "2"
        }
]
}

because of the new nicehash urls and removal of yaamp.
zip archives updated as well: no need to update, only the conf file is changed.

I believe you can extract it from the driver package, but I'm a linux guy so I never tried it myself.

opencl.dll form 14.12? Where can I get the file?

if you are on windows, you can keep your driver and compile the opencl on 14.12 just by putting opencl.dll in the miner's folder.

But i think it's probably drivers' fault

What should I do with the bin file ( i'm newbie in mining ) please send [email protected]

try:
"intensity" : "15",
"gpu-engine" : "835",

I never tried compiling the opencl code using 15.4: it might need tweaking for that version.
You can try 14.12 or I can send you the precompiled bin (64 bit for hawaii).

start file:

setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100

sgminer.exe -c lyra2re.conf

pause

config:

{
"pools" : [
        {
                "name" : "NiceHash_Lyra2RE",
                "url" : "ca.simplemulti.com:3374",
                "user" : "VpzyncgawVk3kC7Yp5M8YHVcS97bYLvQCs",
                "pass" : "x",
                "algorithm" : "Lyra2RE",
                "intensity" : "18",
                "gpu-engine" : "935",
                "gpu-memclock" : "1500",
                "worksize" : "128",
                "gpu-threads" : "2"
        },
   
}


Drivers the latest  15.4 Beta

Which driver version are you using?
Which settings: clocks, intensity etc.?
Please paste the full commandline or conf file.

I'm having 800kh on my r 290 ( 3GB )  what's the problem?

Originally from sph -sgminer, not a copy paste typo, just bad precompiler code ;-)

in fact its just a coding copy paste typo from cpu or ccminer code...

OpenCL doesnt supports ULL, because UL is the same... 64bit

I guess the amd compiler "handles" it but its just wrong...

Thanks very much for testing this!
Long long is not used on amd, there is an ifdef which defines sph_u64 differently on nvidia (legacy sph stuff I didn't care to polish yet).
I will update the two archives and the post, to add intel and nvidia compatibility, later.
High cpu usage can be avoided by setting GPU_USE_SYNC_OBJECTS=1, don't know if there is an equivalent for nvidia.

Just for fun: managed to run it on my gtx 750.
It gives 650 khs instead of 880khs with sp_'s ccminer. Not bad but cpu usage is huge.

In order to make it work I needed to change long long constants in Lyra2cl to unsigned long as long long is not supported in nvidia opencl

__constant static const sph_u64 blake2b_IV[8] =
{
  0x6a09e667f3bcc908UL, 0xbb67ae8584caa73bUL,
  0x3c6ef372fe94f82bUL, 0xa54ff53a5f1d36f1UL,
  0x510e527fade682d1UL, 0x9b05688c2b3e6c1fUL,
  0x1f83d9abfb41bd6bUL, 0x5be0cd19137e2179UL
};

Then it was an error in keccak1600.cl with

inline void keccak_block(ulong *s) {

I added static
inline static void keccak_block(ulong *s) {

and the problems seems to vanish.

Then it was an error with 2d array init skein256.cl

__constant static const ulong ROT256[8][4] = {
   46, 36, 19, 37,
   33, 27, 14, 42,
   17, 49, 36, 39,
   44, 9, 54, 56,
   39, 30, 34, 24,
   13, 50, 10, 17,
   25, 29, 39, 43,
   8, 35, 56, 22,
};

I've added more {} to form this

__constant static const ulong ROT256[8][4] = {
   {46, 36, 19, 37},
   {33, 27, 14, 42},
   {17, 49, 36, 39},
   {44, 9, 54, 56},
   {39, 30, 34, 24},
   {13, 50, 10, 17},
   {25, 29, 39, 43},
   {8, 35, 56, 22}
};

And it finally got compiled.
It works and receives "accepted" from the pool )))

I used "intensity" : "14",   "worksize" : "512",  "gpu-threads" : "1" to run ...
gpu_z shows 100% load for gpu engine and memory, the same is with ccminer )))

I've been using omega drivers when developing it.

Glad it works on Intel GPUs as well! :-)
About the other kernels, you can try adding the missing .cl files into the kernel folder, getting them from the stock sgminer. Not guaranteed to work....

What speed are people getting with this miner with the omega 14.12 drivers?
