1. A method comprising: performing, at a processor, a multi-level integration operation on a plurality of elements, wherein the multi-level integration operation includes a first level of integration and a second level of integration, and wherein performing the multi-level integration operation comprises: generating a first result of a first integration operation performed on a first subset of elements of the plurality of elements, wherein the first integration operation is associated with the first level of integration; generating a second result of a second integration operation performed on the first subset of elements, wherein the second integration operation is associated with the second level of integration; and performing a third integration operation on a second subset of elements of the plurality of elements, wherein the third integration operation is associated with the second level of integration, and wherein the third integration operation is performed based on the first result and the second result.
