I am running a large project with 50 subroutines in it. The problem is three-dimensional with lots of array allocation/deallocation.When I run the project, the iteration ends in 2 to 3 days. During the iteration, RAM usage stuck in maximum of 6 GB RAM ( 98% = 5.375.500 K). How can I decrease the RAM usage effectively ? There are lots of suggestions in forum but I don't want to mix them and make the process to end in longer time. Any suggestion ?
