nonBlockingGaussSeidelSmoother Class Reference

Variant of gaussSeidelSmoother that expects processor boundary cells to be sorted last and so can block later. Only when the cells are actually visited does it need the results to be present. It is expected that there is little benefit to be gained from doing this on a patch by patch basis since the number of processor interfaces is quite small and the overhead of checking whether a processor interface is finished might be quite high (call into mpi). Also this would require a dynamic memory allocation to store the state of the outstanding requests. More...

Detailed Description

Variant of gaussSeidelSmoother that expects processor boundary cells to be sorted last and so can block later. Only when the cells are actually visited does it need the results to be present. It is expected that there is little benefit to be gained from doing this on a patch by patch basis since the number of processor interfaces is quite small and the overhead of checking whether a processor interface is finished might be quite high (call into mpi). Also this would require a dynamic memory allocation to store the state of the outstanding requests.
