CORE FILE LOCATION

   If slurmd is started with the -D option then  the  core  file  will  be
   written  to  the current working directory.  Otherwise if SlurmdLogFile
   is a fully qualified path name (starting with a slash), the  core  file
   will  be  written to the same directory as the log file.  Otherwise the
   core  file  will  be  written  to  the  SlurmSpoolDir   directory,   or
   "/var/tmp/"  as  a last resort. If none of the above directories can be
   written, no core file will be produced.
