components of OFI are: application interfaces, provider libraries, kernel
services, daemons, and test applications.

Libfabric is a core component of OFI.  It is the library that defines and
exports the user-space API of OFI, and is typically the only software that
applications deal with directly.  It works in conjunction with provider
libraries, which are often integrated directly into libfabric.")

     "This package provides a library called libpfm4, which is used to develop
monitoring tools exploiting the performance monitoring events such as those
provided by the Performance Monitoring Unit (PMU) of modern processors.

Libpfm4 helps convert from an event name, expressed as a string, to the event
encoding that is either the raw event as documented by the hardware vendor or
the OS-specific encoding.  In the latter case, the library is able to prepare
the OS-specific data structures needed by the kernel to setup the event.

libpfm4 provides support for the @code{perf_events} interface, which was
introduced in Linux 2.6.31.")
