i can get a successful calculation using a large mixing_beta=16 but for mixing_beta=8 it failed.

i always meet a situation that jobs still run but it didn't output informations and modify the data in out directory (just like endless loops) when i use david diagonalization. that might be caused by poor resources. for cg diagonalization, everything is OK. 

All best
