Its clear... your problem require more memory than you have. <br>

You have one of three options: 1) increase the memory 2) allocate swap space from hard disk or 3) simplify your problem or use lower memory options.<br>

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.<br>
