Papi provides OCaml bindings to
PAPI (Performance Application Programming Interface), a C library
for portable access to hardware performance counters.
The bindings closely follow PAPI's own interface. As a consequence,
the multitude of errors that PAPI can signal are propagated to OCaml. User is
advised to at least skim the PAPI documentation.
Papi depends on the PAPI C library, version 5.4 or above.
Papi is distributed under the ISC license.
