Introdução à Computação Paralela

Esta é a pagina principal de um curso de programacao paralela ministrado em 2012 no IPRJ/UERJ, de utilidade geral para a formacao de programadores de nivel avancado na area cientifica e de processamento multimidia (audio-visual).

General Info

• Meeting times: Tues 12:30pm-2pm, Thursdays 2:20pm - 4pm
• Evaluation criteria: The class will consist on 1 quizz at the end of the term (60%),

plus practical projects (40%).

Pre-requisites

• Linux (will be reviewed as needed)
• C/C++ (will be reviewed)

Approximate Content

The course focuses on software techniques for parallel computing. We are aiming at a comprehensive treatment on different types of practical parallel programming techniques

• process-oriented parallel programming
• thread programming/thread safety
• single-core vector instructions
• multi-processor and multi-core programming
• mapreduce/hadoop
• MPI
• Cuda

Homework

Project 1

• The class will be divided into interest groups
• The interest groups will each pick one of the following technologies or else propose another one of their liking.
  • mapreduce/hadoop
  • MPI
  • Cuda
  • Hybrid technologies (Distributed + Cuda)
  • Languages designed for concurrency: Google Go, Erlang, etc.
  • Programming for the Playstation 3 parallel architecture[1]
• The project will consist in a series of presentations by the group members

individually.

• Grade will be asigned to each presentation individually

Project 1

• This project will consist on a practical programming problem from the

student's research. The student is required to describe a problem from his research and present a parallel implementation of some aspect of it.

• This will be evaluated through actual code and acompanying monograph.
