PAPI is freely available to all users of HPC2N.
PAPI provides the tool designer and application engineer with a consistent interface and methodology for use of the performance counter hardware found in most major microprocessors.
PAPI enables software engineers to see, in near real time, the relation between software performance and processor events. In addition Component PAPI provides access to a collection of components that expose performance measurement opportunites across the hardware and software stack.
On HPC2N we have PAPI available as a module on Kebnekaise.
To use the PAPI module, first add it to your environment. Use:
module spider papi
to see which versions are available, as well as how to load the module and the needed prerequisites.
Note that while the case of the letters does not matter when you use "ml spider", it is necessary to match the case when loading the modules.
More information about using PAPI can be found on the PAPI homepage.
