Abstract:
Data management systems have evolved into an essential component of
numerous applications. Often, they are used to perform "transactional"
workloads comprising transactional, that is, requests that lookup or
update information based on some selection criteria, e.g., looking up
an account's balance or purchasing an item.

For such systems, the higher the throughput, that is he number of
transactions that are serviced per unit of time, the better and often
the more efficient the system.

In this presentation we will observe how transactions execute on
modern hardware and see that transactions operate selfishly. This
behavior ends up penalizing all as it thrashes the instruction caches,
a key performance enhancing mechanism. We will then identify two
cooperative policies that boost throughput. The policies judiciously
decide where, when, and for how long transactions should execute.
While targeting transactional workloads the techniques presented could
potential benefit any workload that has a large instruction footprint
and many threads running over mostly identical pieces of code.
