Separation logic is an extension of Floyd-Hoare logic that makes it possible to reason about programs manipulating pointers. Since its introduction at the beginning of this millenary, it has led to several developments, which include tools for the automatic verification of properties of pointer manipulating programs, as well as reasoning about concurrent programs in a shared memory scenario.
This research school will take place in the week Jan.31st-Feb. 4, 2011.
Courses will be taught in english.
The lecture notes on Separation Logic, written by J. Reynolds and mentioned by H. Yang in his lecture, are available here.
The prerequisite to follow the course is a basic knowledge of first-order logic.
Tool exercises: we suggest that attendees bring a laptop for the sessions devoted to tool exercises. Exercises will be made using the Verifast Program Verifier (follow the link to download and install the tool on your computer).
