1. A method, comprising: loading a set of domain data points into a cache memory, wherein the set of domain points comprises N data points; obtaining an iteration count T, and a first data structure comprising a base stencil operator having a first set of coefficients; generating a second data structure comprising a convolved stencil operator having a second set of coefficients, wherein the convolved stencil operator is generated by convolving the base stencil operator with itself at least one time; and iteratively processing, by a processor, the set of domain data points in the cache memory using the convolved stencil operator no more than T/2 iterations to obtain final processing results; wherein the final processing results that are obtained are similar to processing results that would be obtained by iteratively processing the set of domain data points in the cache memory using the base stencil operator for the iteration count T.
