hi all ..........
I am a new VASP user. My program terminates itself without relaxing after a few steps. And when I take large no. of atoms like 80 or more the program does not start at all and show error like memory allocation .......
What is the program ? has anybody any idea?

you seem to have too little memory to run large jobs:
please either use more parallel nodes,
or reduce the precision, or the k-mesh density to make the run less memory-demanding
