In this paper we study various implementations of Cholesky factorization on SIMD architectures. A submatrix algorithm is implemented on the MasPar MP-2 using both block and torus-wrap data mappings. Both LL T and LDL T (square root free) implementations of the algorithm are investigated. The executi
