In computer science, Performance Application Programming Interface (PAPI) is a portable interface (in the form of a library) to hardware performance counters on modern microprocessors. It is being widely used to collect low level performance metrics (e.g. instruction counts, clock cycles, cache misses) of computer systems running UNIX/Linux operating systems. PAPI provides predefined high level hardware events summarized from popular processors and direct access to low level native events of one particular processor. Counter multiplexing and overflow handling are also supported.

| - Performance Application Programming Interface (PAPI, Прикладной программный интерфейс для анализа производительности) — переносимый интерфейс, реализованный в виде библиотеки, для доступа к на различных современных микропроцессорах. Он широко применяется для сбора низкоуровневых метрик производительности (например, счетчики инструкций, , промахи кэшей) в компьютерных системах, работающих под операционными системами семейства UNIX или Linux. Библиотека PAPI доступна к использованию из программ на языках Си, C++, Fortran, Java, Matlab. (ru)

- Performance Application Programming Interface (PAPI) est une interface de programmation portable (sous la forme d'une bibliothèque logicielle) permettant d'accéder aux compteurs matériels spécifiques aux microprocesseurs modernes. PAPI est utilisé pour collecter des informations de bas niveau, telles que le nombre d'opérations en virgule flottante par seconde (FLOPS), le nombre de cache misses durant l'exécution d'un code, etc. PAPI est interfacé avec les systèmes d'exploitation de type UNIX.

La bibliothèque PAPI est actuellement capable d'accéder aux compteurs matériels de la plupart des processeurs modernes. La liste des processeurs non reconnu ne cesse de diminuer. (fr)
- In computer science, Performance Application Programming Interface (PAPI) is a portable interface (in the form of a library) to hardware performance counters on modern microprocessors. It is being widely used to collect low level performance metrics (e.g. instruction counts, clock cycles, cache misses) of computer systems running UNIX/Linux operating systems. PAPI provides predefined high level hardware events summarized from popular processors and direct access to low level native events of one particular processor. Counter multiplexing and overflow handling are also supported. Operating system support for accessing hardware counters is needed to use PAPI. For example, prior to 2010, a Linux/x86 kernel had to be patched with a performance monitoring counters driver (perfctr link) to support PAPI.Since Linux version 2.6.32, and PAPI 2010 releases, PAPI can leverage the existing perf subsystem in Linux, and thus does not need any out of tree driver to be functional anymore. Supported Operating Systems and requirements are listed in the official repository's documentation INSTALL.txt. (en)
