I run a DMRG code to calculate the correlation function with about 50 sweeps and 500 maxstates. Some tests is killed without any prompt message, while the others are successful. I can also get the results with lower sweeps and maxstates. I wonder if there are some ways to solve this problem or just a better computer.
Generally, Calculating all the correlation functions uses a lot of memory during the last sweep in the ALPS DMRG. So checking the memory usage of the DMRG program using e.g. 'top' might give you some hint.
