We provide a description of the architecture of PSBLAS and its usage in the solution of large and sparse linear systems arising in applications. We will describe the data setup process, the available facilities, and the plugin architecture that enables us to support multiple extensions, e.g. running on NVIDIA GPUs.
Current applications in Computational and Data Science often require the solution of large and sparse linear systems. The notion of "large" is qualitative and there is a clear tendency to increase it; currently, it is not unusual the need to solve systems with millions or even billions of unknowns. The methods of choice to efficiently solve the above systems on high-end massively parallel...
