Assignment Operating Systems and Network Architecture
Assignment Operating Systems and Network Architecture
Question
In previous assignments, you used threads to improve the
performance of a sort algorithm. Threads were initially applied in order to
achieve processing concurrency in order to reduce the time required to sort
data. This week’s readings highlighted various ways that I/O performance can
impact the overall performance of an application or a system. The readings also
identified specific principles that can be applied to improve the efficiency of
I/O.
ORDER NOW FOR AN ORIGINAL NURSING ESSAY ASSIGNMENT ON: Assignment Operating Systems and Network Architecture
For this Assignment, you will consider the I/O performed in
the threaded sort Assignment from Week 2 and how the I/O contributes to the
performance of the threaded sort. Applying the principles identified in this
week’s reading, along with the concurrency control mechanisms from Week 3, you
will revise the threaded sort application in an effort to improve the I/O
performance in order to affect an overall performance improvement.
To prepare:
Evaluate the manner by which the threaded sort application
performs I/O to retrieve the data to be sorted.
Propose a strategy to improve the performance by applying
one or more of the principles to improve the efficiency of I/O that were
identified in this week’s reading.
By Day 7, implement your strategy by modifying your solution
to the threaded sort Assignment from Week 2.
Assignment Operating Systems and Network ArchitectureIn addition, write a 2- to 3-page paper that evaluates how
I/O performance impacts overall program performance. Make sure to include the
following:
A description of your I/O strategy
An explanation on how you expected your strategy to improve
performance
A summary of the actual change in performance observed when
running the updated threaded sort
