Quoting from the DUCC overview at http://uima.apache.org/doc-uimaducc-whatitam.html "DUCC is particularly well suited to run large memory Java analytics in multiple threads in order to fully utilize multicore machines." Our experience to date has been with machines 16-256GB and 4-32 CPU cores. Smaller machines, 8GB or less, have only been used for development of DUCC itself, with dummy analytics that use little memory and CPU.
