G.11 PARDISO – Parallel Sparse Direct and Multi-Recursive Iterative Linear
The PARDISO package is a thread-safe, high-performance, robust, memory eﬃcient and
easy to use software for solving large sparse symmetric and non-symmetric linear systems
of equations on shared-memory and distributed-memory multiprocessor systems [52, 53].
More information is available at https://pardiso-project.org.
When the Matlab interface to PARDISO is installed, PARDISO’s solvers can be used
to replace the built-in ∖ operator for solving for the Newton update step in Matpower’s
default primal-dual interior point solver (MIPS) by setting the mips.linsolver
option equal to 'PARDISO'. The mplinsolve function can also be called directly to
solve problems via PARDISO or the built-in solver, depending on the
arguments supplied. This interface also gives access to the full range of PARDISO’s
options. For details, see help mplinsolve and the PARDISO User’s Manual at
When solving very large AC optimal power ﬂow problems with MIPS, selecting
PARDISO as the linear solver can often dramtically improve both computation time and
Also note that precompiled MEX binaries for a high-performance version of Ipopt,
using the PARDISO linear solver, are available. Refer to Section G.6 for more
