Estimate memory usage

[alexweisberg]

I am attempted to run Spectre's version of SuperQ on a dataset of 91 trees with several hundred taxa. Running this with the quadratic method with JOptimizer primary and secondary solvers like so:
/Software/spectre-1.1.5/bin/superq -b QUADRATIC -f 0.1 -o ./mydataset.SuperQspectre.quad.f0.1.nex -v -x JOptimizer -y JOptimizer ./mynexustrees.tre
ends up using 500GB of heap space (the set maximum and nearly the max for our compute node) before dying. Is there a way to estimate before a run about how much memory would be required for a given dataset? Alternatively are there other options/flags for the program that might reduce the memory requirement? Thanks!
