These files are generated at startup to test disk availability and should disappear (they are deleted by the code) once the DFT starts running. Disk is otherwise not used in your calculation.

Hi,

i'm running nwchem installed from RPM on CentOS 5 x86_64:
(https://nwchemgit.github.io/Special_AWCforum/st/id262/RPMS_of_NWchem.html), with
mpiexec -np 4 nwchem
I want to limit disk io as much as possible (see the attached input below), but still
noticed periodically the presence of "*.junk.[0-3]" files.
For the CH3Cl system one junk file has a size of ~10 Megabytes.
What are the junk files are how to get rid of them?
