Nature of problem:
Computational scientists look upon parallel architectures as a means to fulfil their dream of almost limitless processing power. Such power would enable hitherto unapproachable problems in physics, chemistry and engineering to be tackled. To benefit from the new hardware which is becoming available today there is clear incentive to embody parallel ideas into what we already know i.e. FORTRAN

Solution method:
Codes which presently enable accurate solution of physical problems are almost exclusively written in FORTRAN. Rewriting these codes in a special parallel language cannot be contemplated in less than a decade. We have therefore implemented the Fortnet package to facilitate adaptation of existing FORTRAN codes to the new transputer-based parallel computers.

Restrictions:
None, but see comments on optimisation in section IV.

Unusual features:
Parallel execution, most current transputer architectures require a folding editor to handle Occam code and configuration
