This is the Portable Linux Processor Affinity (PLPA) package (pronounced
"pli-pa"). The PLPA has evolved over time to provide the following
capabilities:

1. Provide a stable API on Linux for processor affinity (Linux has
provided three different API signatures over time).
2. Provide a simple API that translates between Linux processor ID and
(socket ID, core ID) tuples, and allows querying processor topology
information on supported platforms.
3. Provide a command-line executable (plpa-taskset(1)) that provides
all the same functionality as the venerable taskset(1) command, and
several extensions, including the ability to bind processes to
specific (socket, core) tuples on supported platforms.
