Abstract [en]

Abstract. In this paper, we present the StarNEig library for solvingdense nonsymmetric (generalized) eigenvalue problems. The library isbuilt on top of the StarPU runtime system and targets both shared anddistributed memory machines. Some components of the library supportGPUs. The library is currently in an early beta state and only real arith-metic is supported. Support for complex data types is planned for afuture release. This paper is aimed at potential users of the library. Wedescribe the design choices and capabilities of the library, and contrastthem to existing software such as ScaLAPACK. StarNEig implements aScaLAPACK compatibility layer that should make it easy for new usersto transition to StarNEig. We demonstrate the performance of the librarywith a small set of computational experiments.
