DESCRIPTION;ENCODING=QUOTED-PRINTABLE:ABSTRACT: The PAPI library has evolved from a cross-platform interface for accessing processor hardware performance counters to a component-based library for simultaneously accessing hardware monitoring information from various components of a computer system, including processors, memory controllers, network switches and interface cards, I/O subsystem, temperature sensors and power meters, and GPU counters. A GPU component is discussed. =0A=0AA new feature called user-defined events adds a layer of abstraction that allows users to define new metrics by combining previously defined events and machine constants and to share those metrics with other users. =0A=0AOne current effort is the development of a PAPI interface for virtual machines, called PAPI-V, which will allow users to access processor and component hardware performance information from applications running within virtual machines.=0A =0APAPI continues to be widely used by application developers and by higher level performance analysis tools such as TAU, PerfSuite, Scalasca, IPM, HPCtoolkit, Vampir, and CrayPat.
