Hi all,
I’m running DMRG simulations using ITensors.jl, and some of my systems require a very large bond dimension — so large that the memory usage exceeds the capacity of a single node (about 1 TB RAM). I’m using the write_when_maxdim_exceeded=true option in dmrg to offload large tensors to disk, which helps a lot.
However, I would like to ask:
Is there currently a way to limit the total disk usage when using write_when_maxdim_exceeded=true?
This is particularly important for me because I have limited disk space on the compute nodes (e.g., ~800 GB), and uncontrolled growth of disk usage might cause crashes or job termination.
Thanks in advance!
Best
