Query: Modeling the Linux page cache for accurate simulation of data-intensive
  applications   The emergence of Big Data in recent years has resulted in a growing need for
efficient data processing solutions. While infrastructures with sufficient
compute power are available, the I/O bottleneck remains. The Linux page cache
is an efficient approach to reduce I/O overheads, but few experimental studies
of its interactions with Big Data applications exist, partly due to limitations
of real-world experiments. Simulation is a popular approach to address these
issues, however, existing simulation frameworks do not simulate page caching
fully, or even at all. As a result, simulation-based performance studies of
data-intensive applications lead to inaccurate results.
  In this paper, we propose an I/O simulation model that includes the key
features of the Linux page cache. We have implemented this model as part of the
WRENCH workflow simulation framework, which itself builds on the popular
SimGrid distributed systems simulation framework. Our model and its
implementation enable the simulation of both single-threaded and multithreaded
applications, and of both writeback and writethrough caches for local or
network-based filesystems. We evaluate the accuracy of our model in different
conditions, including sequential and concurrent applications, as well as local
and remote I/Os. We find that our page cache model reduces the simulation error
by up to an order of magnitude when compared to state-of-the-art, cacheless
simulations.
