Dear Developers and Users,
I was calculating the band structure of ZB-InN using 'hse' hybrid
functional. It gives the reasonable band gap opening but the run was goes on
and can't stop. Here i am giving some sort of it's output.
Firstly sorry for giving long output data...but have no choice...
Please give me a ray of hope to converges of hse calculation in pw.x.
input....

goes on for atleast total time will take approximate 14 hrs but not stop
the run.
Please any type of comment is appreciable.
