After pondering this problem some more, I found a solution to the problem was to introduce strictness, not deep down in the StateReader monad, but rather at the top level, i.e., forcing evaluation of each Matrix as soon as it is pulled of the list of Matrices. I found I could do this simply by summing all the elements in each matrix and printing the sum to std out. With this approach, i successfully run the full program and never even saw my memory performance graph move up.
I suppose there might be a way to do the same thing more efficiently with seq...?
Undoubtedly, but it's customary when asking for help to produce a complete minimal example that reproduces the problem. I can't help if I can't run your code!
