# Command: nest_serial

NEST HelpDesk | Command Index | NEST Quick Reference

Name:

    nest_serial - Returns a non-distributed call of nest as a string

      Synopsis:  (sli-filename) nest_serial -> (string with shell command)

Examples:

      (hello.sli) nest_serial -> (mpirun -mca btl self,tcp -np 1 /home/dummy/nest/bin/nest hello.sli)

Description:

      If nest was compiled with MPI it may be unsafe to directly call the binary to
      obtain a non-distributed version. The command nest_serial looks up the appropriate
      way to call nest and returns a suitable command as a string. The algorithm is as
      follows:
      1. if nest is not compiled with MPI, return "nest"
      2. if sli command /mpirun is defined, return this with
      the -np 1 equivalent
      3. issue and error with the message that nest was compiled with MPI
      but no method to call nest has been specified.

Diagnostics:

      This function issues an error if NEST was compiled with MPI but is not aware of
      a safe method to call a non-distributed version of nest.
