Flosolver Mk1B - An eight processor parallel machine
The Flosolver MklB has two nodes, each having four processing elements based on intel's 8086/8087 chips. In each node one of the processor acts as the host. The internade communication is done through the parallel ports available on the hosts. Within a node the cynchronisation and inter processor communication is done through the global memory. As a sample case the flow part NACA 0012 aerofoil at zero incident using transonic small perturbation equation is computed and an efficiency of 90 percent is obtained.
We study multiple orthogonal polynomials of Meixner-Pollaczek type with respect to a symmetric system of two orthogonality measures. Our main result is that the limiting distribution of the zeros of these polynomials is one component of the solution to a constrained vector equilibrium problem. We also provide a Rodrigues formula and closed expressions for the recurrence coefficients. The proof of the main result follows from a connection with the eigenvalues of block Toeplitz matrices, for which we provide some general results of independent interest. ::: The motivation for this paper is the study of a model in statistical mechanics, the so-called six-vertex model with domain wall boundary conditions, in a particular regime known as the free fermion line. We show how the multiple Meixner-Pollaczek polynomials arise in an inhomogeneous version of this model.
