Could you upload the zip file including all input files to investigate the origin of error?

Thank you for sending the input files. As far as I checked, I successfully finished the calculation on my laptop.

Could you send me the error messages?

chendahcuan commented 3 years ago

The program has been stuck here

The programs in /samples can run successfully

By changing L in the below input file for Standard mode, could you check how many sites you can treat?

L=21 corresponds to your case.

model = "Hubbard"
method = "Lanczos"
lattice = "chain"
L = 16
t = -1
U = 4
2Sz = 0
nelec = 2

just 14

Why is it so slow to deal with 256*256 matrices
