My personal notes on PAPI

Performance Application Programming Interface (PAPI), primarily maintained by a group at the University of Tennessee

• http://icl.cs.utk.edu/papi/
• Use of low-level performance counter hardware
• CPU, GPU, memory, interconnects, I/O system, energy/power, etc.
• Accesses hardware (processor) counters like instructions, floating point operations, branches predicted/taken, cache accesses/misses, TLB misses, cycles, stall cycles, etc.
• Used by tools like Periscope, Scalasca, TAU, VampirTrace, etc.
