We have a Dell T3610 Xeon based system built up with 128GB of RAM (ECC DDR3, all slots filled), but Pix4D does not seem to be using much of the memory during processing - only 18GB or so is the max I have seen used so far. The baseline job I am processing has 300 36MP images (Sony A7R), and the job was flown for ~80% overlap, and set up for medium point cloud density.
We are getting 100% utilization of CPU (8 cores, 16 threads) and GPU as well (Nvidia GTX-1080), but not the memory.
Running the same job on Trimble Business Center’s Photogrammetry module, ~50GB of 128GB was used. Also, I have run some tests with burn-in software (Prime95) and gotten full utilization of all RAM, so I know that it is working.
Question is, should Pix4D be using more memory than this, if it is available?
