This contribution describes a Square Block, SB, format for storing a banded symmetric matrix. This is possible by rearranging “in place” LAPACK Band Layout to become a SB layout: store submatrices as a set of square blocks. The new format reduces storage space, provides higher locality of memory accesses, results in regular access patterns, and exposes parallelism.
