Dear Mr. Troyer,
I want to estimate how much memory and CPU time the program need to run fulldiag and sparcediag.
1) As I understood, in fulldiag, the main limitation is memory, which have to store the matrix, which is diagonalized. Am I right?
2) What about sparcediag? Does the program also store the matrix, or just generate its elements? Do you think it is possible to find few lowest eigenvalues for the Hubbard model on the 18 sites, with 9 particles (say 4 spins up and 5 down)?
3) Is it possible to have a degeneracy of eigenvalue in sparcediag?
4) How to extract column of eigenvalues from h5-file after running fulldiag?
Thank you in advance, Volodymyr Derzhko
