LAPACK and BLAS do have parallelised libraries PLAPACK and PBLAS, which work 
with PVM on clusters. This is probably the best route to follow, and could 
speed up the numerically intensive stuff. I'd like to keep in touch on this 
process, as I will hopefully be parallelising some of my own geophysical 
algorithms in the near future.
