To this end, it is enough to enable OpenMP on your compiler, for instance: GCC: -fopenmp. You can control the number of threads that will be used using either by the OpenMP API or by Eigen's API using the following priority:

We compute the Schur forms of A and B, viz. UTU* and VSV*, transforming the equation into (2). UTU X + XVSV = C (2) Apply U* on the left and V on the right to transform (2) into the equation below. T (U XV) + (U XV)S = U*CV. Parentheses are added to aid reading. A general SYCT (Sylvester CT) is reduced to triangular SYCT. fernbedienung total control 11-1033r00 https://thejerdangallery.com
