Instructions

Reading digital theses in the closed network of the Aalto University Harald Herlin Learning Centre

In the closed network of Learning Centre you can read digital and digitized theses not available in the open network.

The Learning Centre contact details and opening hours: https://learningcentre.aalto.fi/en/harald-herlin-learning-centre/

You can read theses on the Learning Centre customer computers, which are available on all floors.

Logging on to the customer computers

  • Aalto University staff members log on to the customer computer using the Aalto username and password.
  • Other customers log on using a shared username and password.

Opening a thesis

  • On the desktop of the customer computers, you will find an icon titled:

    Aalto Thesis Database

  • Click on the icon to search for and open the thesis you are looking for from Aaltodoc database. You can find the thesis file by clicking the link on the OEV or OEVS field.

Reading the thesis

  • You can either print the thesis or read it on the customer computer screen.
  • You cannot save the thesis file on a flash drive or email it.
  • You cannot copy text or images from the file.
  • You cannot edit the file.

Printing the thesis

  • You can print the thesis for your personal study or research use.
  • Aalto University students and staff members may print black-and-white prints on the PrintingPoint devices when using the computer with personal Aalto username and password. Color printing is possible using the printer u90203-psc3, which is located near the customer service. Color printing is subject to a charge to Aalto University students and staff members.
  • Other customers can use the printer u90203-psc3. All printing is subject to a charge to non-University members.

Abstract (eng): A sorting network is a network that sorts its input using comparators.
A multi-core processor is a processor that consists of two or more processing cores, which share a common memory.
Sorting networks can be simulated on a multi-core processor utilizing parallel execution.
Simulating sorting networks for different input lengths requires that a block model of the sorting network and a suitable parallel programming method is known.

This thesis shows the block model for five efficient sorting networks.
The block models of all five sorting networks are based on three basic blocks.
It will be shown that several block models can lead to the same sorting network.
Examples will show that different block models for the same sorting network can lead to different simulation times.

A thread pool programming library will be presented as a suitable parallel programming method for simulating sorting networks.
The advantages of this thread pool programming library compared to the parallel programming methods provided by the operating system will be shown by measurements.
Abstract (fin): Lajitteluverkko on komparaattoreista koostuva verkko, joka järjestää syötteensä.
Moniydinsuoritin on suoritin, joka koostuu kahdesta tai useammasta suoritinytimestä, jotka jakavat keskenään keskusmuistin.
Lajitteluverkkoja voi simuloida moniydinsuorittimella rinnakkaissuoritusta hyödyntäen.
Lajitteluverkon simulointi eri syötteenpituuksille vaatii, että lajitteluverkon lohkomalli sekä sopiva rinnakkaisohjelmointimenetelmä tunnetaan.

Tässä työssä esitetään lohkomallit viidelle tehokkaalle lajitteluverkolle.
Kaikkien viiden lajitteluverkon lohkomallit perustuvat kolmeen peruslohkoon.
Osoitetaan, että useampi lohkomalli voi johtaa samaan lajitteluverkkoon.
Esimerkein näytetään, että saman lajitteluverkon eri lohkomallit voivat johtaa eri simulointiaikoihin.

Lajitteluverkon simulointiin sopivaksi rinnakkaisohjelmointimenetelmäksi esitetään tehtäväjonoon perustuva ohjelmointikirjasto.
Tehtäväjono-ohjelmointikirjaston edut käyttöjärjestelmän sisältämiin rinnakkaisohjelmointimenetelmiin osoitetaan mittauksin.
