[QE-users] NEB calculation

[Debashrito Deb]

Dear experts,
I am trying to run the example file of NEB calculation in Cygwin command
prompt.
Once I run the program i am encountering error and the error reads,



executables directory: /home/Administrator/q-e-qe-6.5/bin
  pseudo directory:      /home/Administrator/q-e-qe-6.5/pseudo
  temporary directory:   /home/Administrator/q-e-qe-6.5/tempdir
  checking that needed directories and files exist... done
  running Born-Oppenheimer NEB as: mpirun -np 4
/home/Administrator/q-e-qe-6.5/bin/neb.x  -nk 1 -nd 1 -nb 1 -nt 1
  cleaning /home/Administrator/q-e-qe-6.5/tempdir... done
  running Born-Oppenheimer NEB calculation for H2+H =>
H+H2...--------------------------------------------------------------------------
MPI_ABORT was invoked on rank 0 in communicator MPI_COMM_WORLD
with errorcode 1.
NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.
You may or may not see output from other processes, depending on
exactly when Open MPI kills them.

Aborting

What can be the possible reason ? a little help would be great.
