[Pw_forum] error in scf total energy calculation

[Dhaval Satikunvar]

Hi,

 I am working on Quantum espresso -6.1 installed on linux ubuntu 16.04.
 However, on running the program for scf calculation, I am getting the
 following error on the terminal.

 "Operating system error: Cannot allocate memory
 Allocation would exceed memory limit".

 Please suggest me a possible way to troubleshoot.
