[QE-users] shared library error

[Thomas Brumme]

Dear Haider Abbas,

do all the nodes have access to the same filesystem? I remember getting 
such (or similar) errors
when I wanted to run a job on nodes with separate filesystem... In this 
case be sure that each node
has access to the temporary directory. See also input variables outdir 
and wfcdir

Regards
