       Hi,
      When I try to execute a Gamess parallel job at 2 nodes of my
 cluster with the command line ../ddikick.x ../gamess.01.x exam01 -ddi 2
 2 node01:cpus=1 node02:cpus=1 -scr <dir scr>, I've got the
 following
 error message:
 Distributed Data Interface kickoff program.
 Initiating 2 compute processes on 2 nodes to run the following command:
 ../gamess.01.x exam01
 TCP connect error: ECONNREFUSED.
 TCP: Connect failed. server -> node01:34910.
 A fatal error occurred on DDI Process 2.
 TCP connect error: ECONNREFUSED.
 TCP: Connect failed. server -> node01:34910.
 A fatal error occurred on DDI Process 0.
 Permission denied.
 ddikick.x: Timed out while waiting for DDI processes to check in.
 ddikick.x: Fatal error detected.
 The error is most likely to be in the application, so check for
 input errors, disk space, memory needs, application bugs, etc.
 ddikick.x will now clean up all processes, and exit...
 ddikick.x: Sending kill signal to DDI processes.
 ddikick.x: Execution terminated due to error(s).
                what happens? How can I fix this?
                   Thanks is advance,
                      Alexander.
