We appreciate your quick response.
We obtained the following information from RC, which tells us that we require 128GB of RAM to process 16,000 photographs but they do not specify how much time is required (because they do not know the hardware performance).
Jonathan, what we have thought so far is to separate the 640,000 photographs in 20 different lots, which means that we would need 20 machines working at the same time. * 640,000 / 32,000 = 20
The above means that we need at least 256GB RAM per machine to proceed with processing. But we do not have information about the necessary time, and we would appreciate if you have more information about the planning that you mention.
