One could compile against parallel linear algebra libraries, but this 
is a very fine-grained approach that won't give much of a speedup in 
many cases. If your tasks are reasonably coarse-grained, you can 
directly write parallel Octave scripts using the MPITB toolbox. The 
mle_obj.m function in the econometrics package in octave-forge is an 
example of a script that will run either serially (default) or in 
parallel (when MPITB is available).
