Parfor

[eschardt]

Is it true that parfor is the same as for?
I don't get any speedup when i tell it the number of cores to use.  If there is no use for parfor, is there some other similar function that I could use?

Yes, parallizing the Octave interpreter has proven to be a difficult task.

There are some octave-forge packages that provide parallel support.
The general package has pararrayfun and parcellfun[1]. The openmpi_ext
package provides access to MPI from Octave[2].
