I looked around and guess this should work with the Intel_r3541 and NVIDIA_r3584_SoG app... - or? ...for the iGPU 'HD Graphics': -cpu_lock_fixed_cpu 3 -low_perf -spike_fft_thresh 2048 -tune 1 2 1 16 -hp ...for the 'GT 730': -cpu_lock -instances_per_device 2 -total_GPU_instances_num 2 -use_sleep -high_prec_timer -low_perf -sbs 128 -spike_fft_thresh 2048 -tune 1 2 1 16 -hp On the iGPU just 1 WU/GPU, and the GT730 with 2 WUs/GPU? Maybe someone with similar hardware made bench test runs and/or have experiences which cmdline settings work fast/best? Until now just 1 (AP&MB) WU/GPU on the iGPU and 2 (AP_OpenCL&MB_cuda50) WUs/GPU on the GT730. Cmdline settings for AP (after bench test runs): ...for the iGPU: -unroll 5 -ffa_block 1472 -ffa_block_fetch 368 -tune 1 64 2 1 -oclFFT_plan 32 8 256 -cpu_lock_fixed_cpu 3 -hp ...for the GT730: -unroll 9 -ffa_block 896 -ffa_block_fetch 448 -tune 1 16 4 1 -oclFFT_plan 256 32 64 -use_sleep -cpu_lock -instances_per_device 2 -total_GPU_instances_num 2 -hp Thanks. |

Don't bother trying to run two concurrent tasks on the GTX730, as it will really struggle to do them. Just now you have no tasks for the GPUs, only a small number for the CPU, having abandoned a fair number that were assigned to the GTX730.
