Does anyone know how to use multiple GPU's with oclvanitygen? I have these two:
Available OpenCL platforms:
0: [Intel(R) Corporation] Intel(R) OpenCL
0: [Intel(R) Corporation] Intel(R)
1: [Intel(R) Corporation] Intel(R) HD Gra
1: [NVIDIA Corporation] NVIDIA CUDA
0: [NVIDIA Corporation] GeForce GT 630M
What would be the command for using both of them if I want an address that starts with 1MYbtc?

-D 0:0 -D 0:1 -D 0:2 (etc for as many GPUs as you have)
Edit: Sorry I'll clarify for future users..
./oclvanitygen -i 1address
gets me..
Available OpenCL platforms:
0: [Advanced Micro Devices, Inc.] AMD Accelerated Parallel Processing
0: [Advanced Micro Devices, Inc.] Tahiti
1: [Advanced Micro Devices, Inc.] Tahiti
2: [AuthenticAMD] AMD FX(tm)-4130 Quad-Core Processor
So if I want to use the 2x GPU but not the CPU then I'll run..
./oclvanitygen -i 1address -D 0:0 -D 0:1
or if I want to only use the CPU then I'll do..
./oclvanitygen -i 1address -D 0:2
(yes you can use multiple processes so I could mine one address with one GPU and another with the other GPU)

Hmm, I was interested after your previous question, and tried to install it myself. Unfortunately I keep getting the
vanitygen: pattern.c:164: vg_exec_context_init: Assertion `vxcp->vxc_key' failed.
error, and I have no sudo-rights to fix it right now.
However, to fix your problem, it runs on CPU, not GPU. And it already uses all CPU's, according to the README. If you have a quad-core CPU there will be 4 workers who have ~100% CPU each. If you want to limit the amount of CPU's used, use the -t <threads>-option.

on Windows for example:
oclvanitygen.exe -D 1:0 1YourName
Hey sorry, I meant OCLvanitygen. – rahulgarg12342 – 2014-06-30T14:33:27.667
Oh crap. I didn't knew that also existed – Mathias711 – 2014-06-30T14:50:35.043
