Hi, everyone I'm using sparsediag to get the ground state of Hubbard model, e.g. L=12, with the particle number constraint Nup_total=6, Ndown_total=6. Using the command line. If I calculate the correlation function , it takes 900 sec, if not it takes 100 sec, does anyone know how to speed up this calculation?
Btw if I use python to run the result, I can't see the result from the task.out.xml file, how to look up the result
