JOSTLE is a software package designed to partition unstructed meshes (for example, finite element or finite volume meshes) for use on distributed memory parallel computers.
It can also be used to repartition and load-balance existing partitions (such as those deriving from adaptive refined meshes).
It achieves this by modelling the mesh as an undirected graph and then using state-of-the-art graph partitioning techniques.
The code is extremely fast and provides high quality multilevel partitioning
and diffusive load-balancing in both serial & parallel.
Since its first release in 1995, JOSTLE has gained a worldwide user community of around 150 licensed sites.
Although some are no longer current, it has been licensed by groups based at Los Alamos, Argonne & Sandia National Labs (all in the USA), NASA, and in Universities across the world (specifically the USA, Canada, Brazil, Austria, Belgium, Czech Republic, Finland, France, Germany, Greece, Holland, Italy, Poland, Russia, Spain, Sweden, Switzerland, Turkey, Israel, Oman, India, Japan, Singapore & Taiwan).
JOSTLE has recently been commercialised and is available under the name of NetWorks.

After 20 years as a free software package, JOSTLE has been withdrawn from service.
As an alternative, take a look at the commercial version, NetWorks.
