Explanation of where the parfu name comes from.

Parfu version 0.6 (the full C++ port of the code with major performance and structural improvements over previosu versions) has been in development as of summer/fall 2022. In late fall through winter 2022 we are running performance testing on 8 different NSF ACCESS systems. Access to these systems was granted with an XSEDE Startup Request that was granted June 21, 2022.

The 2022 work on parfu was supported by Blue Waters closeout funding. I thank the Blue Waters Project Office for the opportunity. The performance results currently being collected are being rolled into a paper that will be submitted sometime in 2023.
