The shell software GOSPEL is an example of how a PSE can be designed for EHL modelling using a Grid resource. With the PSE, one can visualise the optimisation progress, as well as interact with other simulations.<ref name=":3">{{Cite web|url = http://www.comp.leeds.ac.uk/pkj/Papers/Conf-O/GBJS03.pdf|title = Grid-Based Numerical Optimisation in a Problem Solving Environment|date = |access-date = 2015-11-03|website = |publisher = The University of Leeds|author1=C.E.

The PSE parallelise and embed many individual numerical calculations in an industrial serial optimisation code. It is built in NAG's IRIS Explorer package to solve EHL and [[Parallel computing|Parallelism]] problems and can use the gViz libraries, to run all the communication between the PSE and the simulation. It also uses MPI — part of the NAG libraries — which gives significantly quicker and better solutions by combining the maximum levels of continuation.<ref name=":3" />
 
Moreover, the system is designed to allow users to steer simulations using visualised output. An example is utilising local minima, or layering additional details when around a local in and out of the simulation and it can imagine the information which is produced in any sharp and also still allow to steer the simulation.<ref>{{Cite web|url = http://www.comp.leeds.ac.uk/vis/kwb/e-science/paper098.pdf|title = A Distributed Co-operative Problem Solving Environment|access-date = 2015-11-03|publisher = The University of Leeds|author1=Mark Walkley |author2=Jason Wood |author3=Ken Brodlie |name-list-style=amp }}</ref>
