Title HSL_MA97 : a bit-compatible multifrontal code for sparse symmetric systems
Abstract The multifrontal method is widely used for the numerical solution of large sparse symmetric linear systems of equations. In this report, we discuss the design and implementation of a new multifrontal code HSL_MA97. Our motivation for the new code is discussed along with the key design features. HSL_MA97 is for real and complex problems and is designed to be efficient for both positive definite and indefinite systems. HSL_MA97 can be run in serial or in a shared memory environment using OpenMP. An important feature is that in parallel it offers bit-compatible solutions. Numerical results are presented for a range of problems from practical applications and comparisons are made with existing codes. Future plans for HSL_MA97 are outlined.
