  In this paper, we present the StarNEig library for solving dense
non-symmetric (generalized) eigenvalue problems. The library is built on top of
the StarPU runtime system and targets both shared and distributed memory
machines. Some components of the library support GPUs. The library is currently
in an early beta state and only real arithmetic is supported. Support for
complex data types is planned for a future release. This paper is aimed for
potential users of the library. We describe the design choices and capabilities
of the library, and contrast them to existing software such as ScaLAPACK.
StarNEig implements a ScaLAPACK compatibility layer that should make it easy
for a new user to transition to StarNEig. We demonstrate the performance of the
library with a small set of computational experiments.
