So probably the installed pserver.oct is compiled for Octave-3.2.., i.e. not usable with Octave-3.0.5 (and also not in its path).

Its not necessarily true that the server is already running, maybe there was a crash already then and the pid-file was not deleted in /tmp/. One could check whether 'ps ax | grep octave' gives the same as 'cat /tmp/.octave-domU-12-31-39-0E-B0-B2.pid'. > panic: Segmentation fault -- stopping myself... > attempting to save variables to `octave-core'... > save to `octave-core' complete > Segmentation fault I don't know where this crash comes from. May be not even from 'parallel'. You probably do not have the original version 2.0.0 of 'parallel' installed, since this did not compile at all with the Octave-3.2.. series. So it might help to install the original package from Octave-Forge manually. For Octave-3.2.., use parallel-2.0.1 (no such crash on my machine with Octave-3.2.4). For Octave-3.0.5, an earlier version of 'parallel' might work.
