This paper presents a new idea of developing parallel programs for clusters of SMP nodes using the Ada programming language. We show how to implement OpenMP in Ada and simplify programming of distributed memory applications using remote subprograms calls instead of complicated message passing. 1. Introduction While the largest computers in the world are(More)
The aim of this paper is to show that linear recurrence systems with constant coefficients can be efficiently solved on hybrid GPU accelerated manycore systems with modern Fermi GPU cards. The main idea is to use the recently developed divide-and-conquer algorithm which can be expressed in terms of Level 2 and 3 BLAS operations. The results of experiments(More)
The aim of this paper is to show that the recently developed algorithm for solving linear recurrence systems on shared-memory parallel computers can be efficiently implemented on high performance message passing parallel and vector computers and clusters of workstations. We analyze the performance of the algorithm using two well known models: BSP and(More)
The aim of this paper is to show that a special kind of boundary value problem for second-order ordinary differential equations which reduces to the problem of solving a tridiagonal system of linear equations with almost Toeplitz structure can be efficiently solved on modern heterogeneous computer architectures based on CPU and GPU processors using an(More)
