Thanks for pointing this out for both local and remote execution. This changeset:

https://sourceforge.net/p/octave/parallel/ci/4045205aad9c969271022c7416586521244b76e7/

should fix this for both by first trying the octave-cli-VERSION and then octave-cli.

In both local and remote parallel modes, the parallel package runs Octave as the 'octave-cli' binary. However, this command name is not safe, 'octave-cli-${OCTAVE_VERSION}' should be used instead.

Example on a system where the 'octave-cli' symlink does not exist in the same directory as 'octave-cli-6.0.1':

>> y = parcellfun (...)
open: No such file or directory
couldn't set executable
open: No such file or directory
couldn't set executable
error: can't reset scheduler
error: called from
    parcellfun at line 117 column 9
    pararrayfun at line 85 column 28

Example on a system where the 'octave-cli' symlink exists but points to a different version of Octave that doesn't have the parallel package installed:

>> y = parcellfun (...)
error: package parallel is not installed
could not load variable
could not save variable.
error: package parallel is not installed
could not load variable
error: __parcellfun_initialize_job__: could not initialize job
error: called from
    parcellfun at line 181 column 7

I'm aware that the Debian and Ubuntu packages only install /usr/bin/octave-cli, without the version suffix, but maybe that target can be treated as a special case, either detected at install time or at run time. In general, if you want to handle both possibilities, I'd think that 'octave-cli-${OCTAVE_VERSION}' should always be preferred if it exists.
