oclHashcat benchmark with Apple CPU + GPU

[forumhero]

You are confusing --opencl-device-type for --opencl-devices. When you specify ''--opencl-device-type 3'' you're telling oclHashcat to only use devices which present themselves as CL_DEVICE_TYPE_ACCELERATOR (3) when you want CL_DEVICE_TYPE_GPU (2). So if you want to run on only your Nvidia GPU, you would use ''--opencl-device-type 2 --opencl-devices 3''.

thank you for that.  I should've read the help, doh!

GPU only

Code:

./oclHashcat.app -b --opencl-devices 3 oclHashcat v2.01 (gd0d3507) starting in benchmark-mode... Device #1: Intel(R) Core(TM) i7-3615QM CPU @ 2.30GHz, skipped Device #2: HD Graphics 4000, skipped Device #3: GeForce GT 650M, 256/1024 MB allocatable, 900Mhz, 2MCU Hashtype: MD4 Workload: 16 loops, 256 accel Speed.Dev.#3.:   221.1 MH/s

CPU and GPU

Code:

./oclHashcat.app -b --opencl-device-type 1,2 --opencl-devices 1,3 oclHashcat v2.01 (gd0d3507) starting in benchmark-mode... Device #1: Intel(R) Core(TM) i7-3615QM CPU @ 2.30GHz, 4096/16384 MB allocatable, 2300Mhz, 8MCU Device #2: HD Graphics 4000, skipped Device #3: GeForce GT 650M, 256/1024 MB allocatable, 900Mhz, 2MCU Hashtype: MD4 Workload: 16 loops, 64 accel Speed.Dev.#1.:   282.7 MH/s Speed.Dev.#3.: 40020.5 kH/s Speed.Dev.#*.:   322.7 MH/s

I have to make sure to exclude the HD Graphics otherwise I get this error everytime

Code:
