报告摘要：
Teaching computer science without a computer — also called,  unplugged computer science, — is an interesting approach to let people understand what an algorithm is, and what kind of problems we face as a computer scientist. In this short seminar, I’ll present some of the ideas behind unplugged computer science, and I’ll let the attendants practice an example related to parallel computing.

个人简介：

Patrice Quinton is Professor Emeritus in Computer Science at Ecole normale supérieure de Rennes, France. Formerly President of ENS Rennes, he graduated in 1972 from ENSIMAG in Grenoble, and obtained a PhD degree in Computer Science from the University of Rennes 1 in 1980. His scientific interests are parallel computing and parallel architectures, in particular, the synthesis of parallel program using the polyhedral model of loops.

报告摘要：
We discuss scheduling strategies for the problem of maximizing the expected number of tasks that can be executed on a cloud platform within a given budget and under a deadline constraint. The execution times of tasks follow IID probability laws. The main question is to decide whether and when to interrupt tasks that have been executing for some time.
