help with problem " forrtl: severe (29): file not found, unit 8"
Posted: Thu Apr 22, 2010 4:07 pm
Dear all,
The compute I am using is a server with two quad core CPUs and the OS is ubuntu server. VASP version 4.6 and 5.2.
There is no problem when I run small calculations(half day work). When I try to run a large (2x2x1) supercell (16 atoms in total) with a 8x8x10 or larger kpoint mesh, it works at the beginning and give reasonable reults, but it stops in the middle. The error message is "orrtl: No such file or directory forrtl: severe (29): file not found, unit 8 ".
I don't understand why it suddenly can't find the OUTCAR file after it wrote it for quite some times.
Very frustrating, can anyone help me out? Thank you very much.
