The PARDISO Version 5.0.0 has been released in January 2014. It contains full support of multi-threaded Schur-complement computations and full support for parallel selected inversion. The new features are described in the following papers:
- M. Luisier, O. Schenk et.al., Fast Methods for Computing Selected Elements of the Green's Function in Massively Parallel Nanoelectronic Device Simulations, Euro-Par 2013, LNCS 8097, F. Wolf, B. Mohr, and D. an Ney (Eds.), Springer-Verlag Berlin Heidelberg, pp. 533–544, 2013,
- C. Petra, O. Schenk, M. Lubin, K. Gärtner, An augmented incomplete factorization approach for computing the Schur complement in stochastic optimization, SIAM J. Sci. Comput, accepted, in press.
Additional publications related to PARDISO are available on the webpage of the research group of Olaf Schenk.
Important: Please note that the Intel MKL version of PARDISO is based on our version from 2006 and that a lot of new features and improvements of PARDISO are not available in the Intel MKL library.
How To Use PARDISO

Ipopt 3.12.1 (extended version), PARDISO 5.1.0 (threaded version)
You need to set the numbers of threads with, for example, if you would like to use 8 cores you should use
export OMP_NUM_THREADS=8 before running ipopt.mexa64 in Matlab.
In addition, you need a PARDISO license file pardiso.lic which can be obtained here.
