From: HASE: Framework for efficient high-dimensional association analyses

Explanation of the achieved speed reduction in HASE framework by removing redundant computations.
In HASE multi-dimensional (A,B) matrices need to be calculated to perform GWAS studies. In the figure grey color means elements are parts of the matrix that are not necessary to calculate, as the A matrix is symmetric. The green color indicates elements that need to be calculated only once. Blue elements only have to be calculated for every SNP and yellow only for every phenotype. The red color indicates the most computationally expensive element, which needs to be calculated for every combination of phenotype and genotype. N denotes the number subjects in study.
