PAPR meaning in Academic & Science ?

Answer: What is Power Architecture Platform Reference mean?

Power Architecture Platform Reference (PAPR) is an initiative from Power.org to make a new open computing platform based on Power ISA processors. It follows two previous attempts made in the 1990s, PReP and CHRP.

The PAPR specification provides the foundation for development of standard server computers. Various operating systems like Linux and IBM AIX rely on the PAPR interface to run on Power-based hardware. PAPR is Power.org's move toward what IBM did originally with PReP, in that it defines a common hardware definition and software/firmware platform under a set of requirements. In practice, the PAPR is an extension to the Open Firmware specification.

Since 2013, extensions have been done by the OpenPOWER Foundation, which released a slightly reduced public version of the PAPR standard for running Linux on Power hardware (called LoPAPR) [1].In 2020, LoPAPR was renamed to Linux on Power Architecture Reference (LoPAR) [2] with the release of a new version.
