dear all,
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. . thank you very much

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.
Best regards,
thank you...
