I found memory leak issue, when I ran Parallel_HOP code. It may not be in python itself but may be in packages(e.g. kdtree etc..), which we call from"parallel_hop_interface.py". Please find attach file, in which you see memory keep increase in every region
(I ran program with 32 processes for 0-3 regions.)
I like to get your comments/suggestions to solve this issue.
I am trying to find more about it using Valgrind. I will let you know.
