We introduce a method of constructing classes of graphs by algorithmic removal of entire groups of edges. Our approach to creating new classes of graphs is to focus entirely on the structure and properties of the adjacency matrix. At an initialisation ste... see more

We demonstrate that a live-programming environment can be used to harness and add run-time interactivity to scientific simulation codes. Through a set of examples using a Particle-In-Cell (PIC) simulation framework we show how the real-time, human-in-the-... see more

Numerical solution of the quantum mechanical Schrödinger equation is required to model electronic excitations in the light-harvesting photosynthetic complexes composed of up to millions of atoms. We demonstrate that the modern supercomputers can be used t... see more

The INMOST mathematical modeling toolkit helps a user to formulate and solve a problem of partial differential equations on general meshes in parallel. The current work covers: data structure description for efficient distributed unstructured mesh represe... see more

We present a review of the current best practices in parallel programming models for dense linear algebra (DLA) on heterogeneous architectures. We consider multicore CPUs, stand alone manycore coprocessors, GPUs, and combinations of these. Of interest is ... see more
