Re: Wolf's XMR GPU Miner

Quote from: cryptocurrencyfuture on October 13, 2016, 01:36:39 AM

(Updated with code tags that I didn't do originally - apologies for that as I'm new to this forum and Wolf's XMR GPU miner)

As originally stated I'm new to GPU mining and have been following this thread for Wolf's XMR GPU Miner where I have done the following below:

1. Fresh minimal install of Ubuntu 16.04 Server with OpenSSH Server along with latest updates for headless remote SSH access
2. Installed AMDGPU-PRO Driver version 16.30.3-315407 with sudo privileges
3. Installed AMD APP SDK 3.0 with sudo privileges in the /opt/AMDAPPSDK-3.0 directory location
4. Cloned the GitHub repository at https://github.com/wolf9466/wolf-xmr-miner
5. Updated the Makefile with the following changes for new AMDAPPSDK-3.0 installation

Code:

CC = gcc
LD = gcc
OPT = -O2 -s -I/opt/AMDAPPSDK-3.0/include -L/opt/AMDAPPSDK-3.0/lib
CFLAGS = -D_POSIX_SOURCE -D_GNU_SOURCE $(OPT) -c -std=c11
LDFLAGS = -DPTW32_STATIC_LIB $(OPT)
LIBS = -ljansson -lOpenCL -lpthread -ldl

6. Execute make without any errors and only warnings

Code:

$ make

7. Configure the xmr.conf as needed

Code:

{
"Algorithms":
[
{
"name": "CryptoNight",
"devices":
[
{
"index": 0,
"threads": 1,
"rawintensity": 640,
"worksize": 8
},
{
"index": -1,
"threads": 1,
"rawintensity": 8,
"worksize": 8
}
],
"pools":
[
{
"url": "stratum+tcp://:",
"user": "",
"pass": "x"
}
]
}
]
}

8. Execute the miner and get this error a few seconds later

Code:

$ ./miner xmr.conf

[17:32:27] Setting up GPU(s).
[17:32:27] Successfully connected to pool's stratum.

Any help with getting further along would be greatly appreciated as my next step is trying one AMD GPU card installed at a time to see what happens

1. I resolved the issue I was having before by modifying the compiler options further with the -D_FORTIFY_SOURCE=0 option shown below

Code:

OPT = -O2 -s -I/opt/AMDAPPSDK-3.0/include -L/opt/AMDAPPSDK-3.0/lib
CFLAGS = -D_POSIX_SOURCE -D_GNU_SOURCE $(OPT) -c -std=c11 -D_FORTIFY_SOURCE=0
CC = gcc
LD = gcc
LDFLAGS = -DPTW32_STATIC_LIB $(OPT)
LIBS = -ljansson -lOpenCL -lpthread -ldl

2. I can successfully CPU and GPU mine XMR with the following xmr.conf file

Code:

{
"Algorithms":
[
{
"name": "CryptoNight",
"devices":
[
{
"index": 0,
"threads": 2,
"rawintensity": 1024,
"worksize": 8
},
{
"index": 1,
"threads": 1,
"rawintensity": 640,
"worksize": 8
},
{
"index": -1,
"threads": 3,
"rawintensity": 12,
"worksize": 12
}
],
"pools":
[
{
"url": "stratum+tcp://:",
"user": "",
"pass": "x"
}
]
}
]
}

3. Current output example from my wolf-xmr-miner build and configuration listed above

Code:

4. I will continue to play around with the best settings for xmr.conf and find the best performance and stability.

5. I haven't done any overclock/undervolt efforts on the stock AMD GPUs and will see what options might help performance along with stability as time permits.

At this point I'm just happy to have it working now using stock settings and hope this information helps others attempting to use the wolf-xmr-miner on Ubuntu 16.04 LTS in the future. Thanks to Wolf again for sharing with others and making this wonderful GPU miner.
