I got this question from a lot of people in the last few weeks and so I thought to write a blog post about it so that all the interested students can use get to know this information.
If you are here I assume that you have a pretty good idea about what GSoC is, and if you don’t, please check my post on Intro to Google Summer of Code

Before getting started let’s see why I am qualified to talk about this.
CERN-HSF has the highest number of GSoC project approvals(to my knowledge) in the recent years and accomodate around 25–35 student projects each year whereas many organizations get only 2–3 project slots. It gets 100s of student applications each year and I think it is safe to say that CERN-HSF is one of the most competitive organization in the GSoC program. CERN houses the world largest particle accelerator and the world’s largest computing grid. Last summer I did my GSoC project “Framework for Automating the Retrieval and Analysis of System Information of Grid sites in WLCG” with ALICE project at CERN working on this world’s largest computing grid called Worldwide Large Hadron Collider Grid(WLCG). Since the end of the GSoC, i work as a remote contributor at CERN upto now. There are 5 major experiments at CERN and ALICE(A large Ion Collider Experiment) is one of them.

CERN Organizational Structure

If you are here, I assume you already know what CERN is and if you don’t you can get more information from here . In simple words CERN is a collection of small organizations and educational institutes researching on particle physics. So, unlike the other organizations, if you are applying to CERN, you have to choose a sub organization in CERN-HSF and apply to one of them. This abstraction is not clear at the official GSoC page for CERN but can be found at their own GSoC information page. Many of this sub organizations maintain one or more products/tools of their own and presents 2–3 GSoC project ideas under the CERN-HSF organization. Although the final proposal are always submitted through the GSoC page, the initial phase of discussing the projects, passing the tests etc. are…
