The course is aimed at providing students with a comprehensive vision of the foundations of concurrent and distributed programming. The main focus of the lectures is on system models and on different types of frameworks intended to support the development of concurrent systems at different abstraction levels and on different underlying platforms.

Students will acquire the basic skills to participate in the design, implementation and integration of concurrent and distributed software systems, possibly made of heterogeneous components.

Prerequisites: knowledge of Operating Systems basics, and mastering of Java and C/C++.

-   ATTENTION: An extra oral exam is scheduled on Dec. 3rd, 2020 h. 8:30 am, to be held online on the MS Teams platform. No sign-in is required: please confirm participation to the teacher by email.

-  The dates for oral exams are reported on the website of the School of Engineering. Students are required to register through the Exam Sign-in Portal at least two days before the exam date.

 

First lecture on Wed. Sept. 26th, 2018

Mon. 11:30-13:30 ADII 2 (usually, Bechini); Tue. 14:30-16:30 ADII 1 (usually, Bechini); Wed. 8:30-10:30 ADII 1 (usually, Bechini); Thu. 13:30-15:30 ADII 2 (usually, Lettieri)

The lectures' schedule and relative updates, as well as exam dates, are available on a public Google Cal, which can be imported with the following ICS address:

A detailed description is available via the record of lessons (see the left menu item).
Hereafter, a cathegorized list of topics can be interactively explored.

The final test is organized as follows:

a)   development of a project; specifications must be agreed upon with the teacher; the finalized work must be shown to the teacher for final approval prior to the oral exam (not in the same date)
b)   oral exam (possibly with written exercises), on all the topics covered by the course.

All the course contents are covered within the textbooks and other material reported hereafter. These references can also be taken as suggestions for in-depth discussions on class topics.
