Parallel eigensolver operations are at the computational core of many large-scale scientific and engineering application codes. This project analyses parallel performance of established and newly developed parallel dense symmetric eigensolver numerical library routines on PRACE Tier-0 systems using real datasets from large-scale application codes. This whitepaper builds upon the research report 'Dense Linear Algebra Performance Analysis on the Fujitsu BX900 OPL Machine†' (from the same author)

This version of the report is updated with results from ScaLAPACK and with the recently released ELPA library routines on the PRACE Tier-0 machines CURIE and JUGENE.
