Presentations by Students
Propose Presentations before Saturday 22, 12:30
View the proposals posted so far

Students are invited to propose a topic they would be interested in presenting, during a special one-hour session to take place the second Tuesday afternoon. Those selected will be invited to give a short presentation (in the order of 5 to 10 minutes maximum).

The presentation, in particular if short, would not necessarily require presentation material (such as PowerPoint slides)

The choice of topic is free but should be related in some way to the school. Examples, you may briefly talk about:

  • A scientific / technical topic (such as examples only)

    • HEP, HEP computing, on-line, off-line, , ...

    • HEP Sister disciplines, Computer science, ...

    • Other

  • Your presence here

    • Why are you here, where do you come from, what is your discipline, what are you expecting from the school, how do you think you will be exploiting the knowledge acquired here, ...

Note: if you are presenting in a group, please select one of you to use the login and password and write the names of all members of the group in the description.

Screen: The Swiss knife for remote sessions
(view the slides)

We spend days and nights using remote SSH sessions and dealing with annoying problems like disconnections, multiple windows, repetitive tasks, etc... GNU Screen is a 'terminal multiplexer' which allows you to run multiple applications simultaneously within a single terminal. It also includes handy features for making the day-to-day work easier, like session sharing and reconnection. This presentation will describe how to use screen and its most important benefits.

Response Time Optimization in Web Applications
(view the slides)

Response time in web applications is one of the most important issues today. The whole stack of intermediate software we use to deliver web interfaces added to the increasing popularity of web services make web applications very slow. In this short presentation we will give an overview of the stack of technologies used nowadays in web applications. Then we will present one or two example methods and we will apply them to a concrete webpage to see the reponse time improvement.

Improving the traceability of your code while keeping it clean 
(view the slides)

Debuggers just can't solve all problems. Sometimes we need information about what's going on in our software while it is in production, and we need this information separated from the real output of our program. The usual approach of flooding the code with print statements makes uglier, and the messages are often inconsistent. I'd like to explain briefly what alternatives we have on different languages and platforms, focusing mainly on the use of syslog, and log4XXX

What does my machine really do? - Using Systemtap to analyze performance and functional problems 
(view the slides)

SystemTap provides free software (GPL) infrastructure to simplify the gathering of information about the running Linux system. This assists diagnosis of a performance or functional problem. SystemTap eliminates the need for the developer to go through the tedious and disruptive instrument, recompile, install, and reboot sequence that may be otherwise required to collect data. I will give a short overview on Systemtap and will present how it can be used to profile and analyze grid-jobs.

MPI on a non-
dedicated "cluster" 
(view the slides)

After a short outline on my topic (wave-optical simulations in the x-ray regime) we will have a look at not-so-performant parallelization on a highly visited set of computing nodes, the ESRF coral
