Distributed Computing frameworks belong to a class of programming models that allow developers to
launch workloads on large clusters of machines. Due to the dramatic increase in the volume of
data gathered by ubiquitous computing devices, data analytic workloads have become a common
case among distributed computing applications, making Data Science an entire field of
Computer Science. We argue that Data Scientist's concern lays in three main components: a dataset,
a sequence of operations they wish to apply on this dataset, and some constraint they may have
related to their work (performances, QoS, budget, etc). However, it is actually extremely
difficult, without domain expertise, to perform data science. One need to select the right amount
and type of resources, pick up a framework, and configure it. Also, users are often running their
application in shared environments, ruled by schedulers expecting them to specify precisely their resource
needs. Inherent to the distributed and concurrent nature of the cited frameworks, monitoring and
profiling are hard, high dimensional problems that block users from making the right
configuration choices and determining the right amount of resources they need. Paradoxically, the
system is gathering a large amount of monitoring data at runtime, which remains unused.
In the ideal abstraction we envision for data scientists, the system is adaptive, able to exploit
monitoring data to learn about workloads, and process user requests into a tailored execution
context. In this work, we study different techniques that have been used to make steps toward
such system awareness, and explore a new way to do so by implementing machine learning
techniques to recommend a specific subset of system configurations for Apache Spark applications.
Furthermore, we present an in depth study of Apache Spark executors configuration, which highlight
the complexity in choosing the best one for a given workload.

A detailed study is presented of the expected performance of the ATLAS detector. The reconstruction of tracks, leptons, photons, missing energy and jets is investigated, together with the performance of b-tagging and the trigger. The physics potential for a variety of interesting physics processes, within the Standard Model and beyond, is examined. The study comprises a series of notes based on simulations of the detector and physics processes, with particular emphasis given to the data expected from the first years of operation of the LHC at CERN.

William Van Every, son of McGregory and Mary Wilcox (Jaycocks) Van Every, was born in New York state in 1765. During the Revolutionary War he joined Butler’s Rangers and served under Captain John McDonnell. He was granted three lots of land in the Township of Niagara, with additional lands granted at later dates. William married Elizabeth, daughter of George Young. Elizabeth was the widow of Col. Frederick Dochstader and mother of Catherine Dochstader, b. 1781. William Van Every died in 1832, his wife Elizabeth in 1851. Both are buried in the Warner Cemetery, in present day Niagara Falls. The children of William Van Every and Elizabeth Young were Mary, Elizabeth, Phoebe, John, Peter, William, Rebecca, Samuel and Joseph.
