This article explains how PIX4Dmapper utilizes each hardware component at each processing step.
Information:
The software is highly parallelized and takes advantage of multi-core CPUs, as well as MMX/SIMD instructions and NVIDIA GPU Cuda processing. However, the different steps of the processing do not use the resources the same way, and not all parts can take advantage of multi-core or CUDA.
Step 1
