Algorithm was re-programmed from scratch
But it needed an estimated 9 Days of CPU time on a single J90 processor (or Cray T3D node) to perform a single UK run using census Ed data
Fortunately:
- a modern workstation is as fast as a Cray J90 processor
- a single run could be completed in less than 1 hour on a 512 processor Cray T3D, however..
This would hardly constitute a generally applicable and easy to use method!
