* Huge speed win for the relaxation dispersion analysis - optimisation now uses the multi-processor. The relaxation dispersion optimisation has been parallelised at the level of the spin clustering. It uses [https://{{gna link|url=gna.org/users/varioustoxins |text=Gary Thompson's] }} multi-processor framework. This allows the code to run on multi-core, multi-processor systems, clusters, grids, and anywhere the OpenMPI protocol is available. Because the parallelisation is at the cluster level there are some situations, whereby instead of optimisation being faster when running on multiple slaves, the optimisation will be slower. This is the case when all spins being studied in clustered into a small number of clusters. It is also likely to be slower for the [http://www.nmr-relax.com/manual/minimise.html minimise user function] when no clustering is defined, due to the overhead costs of data transfer (but for the numeric models, in this case there will be a clear win). The two situations where there will be a huge performance win is the [http://www.nmr-relax.com/manual/grid_search.html grid_search user function] when no clustering is defined and the Monte Carlo simulations for error analysis.
