Summary: Large memory usage on first evaluate with many
OS/Version: Mac OS
Estimated Hours: 0.0
'm trying to optimize a set of particles as done for the alpha-globin domain
(I'm doing some testing on a larger chromatin domain) using a large set of
restraints (over 10^6 restraints).
The memory usage is OK until all the restraints are generated (~2GB), and then
increase to 100% of memory and swap (16GB + 16GB) when I first call
m.evaluate(False) (to check the initial score) causing the script to stop. I
understand that a large number of restraints are being evaluated, but I was
wondering if this is an expected behavior (i.e. if there is a sort of
limitation in the number of restraints that can be implemented per memory GB)
or if there is a workaround, before trying to run the script on a (shared)
machine with much more memory.
