@section Component Specific Information
infiniband/
The PAPI infiniband component uses the sysfs interface to access infiniband
performance counters from user space. On initialization, it checks for the
existence of folder /sys/class/infiniband/ and it auto-detects all the
active IB devices and associated ports.
This component supports both the short IB counters, which are at most
32-bit, overflowing and auto resetting, thus, not very useful, and the IBoE
extended counters, which are 64-bit and free running. If available, the
latter counters are recommended for performance monitoring.
