[Pw_forum] A small question for hard disk requirement.

[Shaofeng Wang]

Dear pwscf users,

Could anyone give me an estimation of hard disk requirement for a 
calculation of IR spectrum at gamma using 200 atoms? When I tried to 
calculate this supercell, all 40 GB disk was full and not enough for further 
calculation.


Regards,

Shaofeng
