Union Find decoder Out of Memory #65
Description
Hello,
in some recent simulations of mine of the Rotated Surface Code (d=9, r=9) from STIM under very heavy Pauli noise, I noticed that sometimes the UnionFind decoder and the BeliefFind decoder trigger the oom killer and crash.
The PCM has a size of (720, 12705), but it is passed as a CSR matrix.
What could be causing this?
