PAPI aims to provide the tool designer and application engineer with a consistent interface and methodology for use of the performance counter hardware found in most major microprocessors. License: BSD License (original) Changes:
This release adds an alias for PAPI_ENUM_ALL to prevent legacy code from failing and adds support for nanosecond resolution timers, newer dual and quad core processors from Intel and AMD, new systems from Cray, Power6 with Linux, and standardized event names. It fixes an identification problem with some Pentium4 models, overflow support on Intel Core processors, Fortran headers for large negative numbers, and identification of POWER5+ and 5++ processors using AIX. It improves support for fork/exec with overflow and profiling, and improves support for FreeBSD.
