Personal Info
My name is Kornilios Kourtis. I graduated from the School of Electrical and Computer Enginneering at National Technical University of Athens in 2004. My diploma thesis was titled "Design and Implementation of a Network Block Device in the Linux Operating System".
In April 2010, I successfully defended my PhD thesis (englishonly version), under the supervision of prof. Nectarios Koziris.
Updates
17/10/2011: For about a month and a half, I have been working as a postdoc researcher at ETH's Systems Group.
12/06/2011: I've been working on investigating what kind of information about OpenMP constructs can somebody get at compile time using gcc. As a toy example, I've created a gcc plugin that draws a graph of OpenMP constructs. (source, example output)
