Question

(Cholesky factorization) Algorithm 8.6 describes a row-oriented version of the Cholesky factorization algorithm for factorizing a symmetric positive definite into the form A = U^T U. Cholesky factorization does not require pivoting. Describe a pipelined parallel formulation of this algorithm that uses 2-D partitioning of the matrix on a square mesh of processes. Draw a picture similar to Figure 8.11. Algorithm 8.6 A row-oriented cholesky factorization algorithm. procedure CHOLESKY (A) begin for k: = 0 to n - 1 do begin A[k, k]: = Squareroot A[k, k]; for j: = k + 1 to n - l do A[K, j]: = A[k, j]/A [k, k]; for i: = K + l to n - l do for j:= i to n - 1 do A[i, j]: = A[I, j] - A[k, i] x A[K, j] endfor;/* Line3 */end CHOLESKY

Explanation / Answer

the conceivable advantages every intercession may present and figured the fiscal estimation of the

part of advantages that could be distinguished and measured in view of the outcomes revealed in the effect

assessment. We then processed fitting monetary measurements – advantage cost proportions and net present

values – and performed affectability testing to check whether the outcomes are hearty to option determinations.
