JP09 – Parallel Computing Conferences 2009

Last week I attended the National Parallel Computing Conferences 2009 (JP09) as I did last year. Again, I must thank to my university, which payed to us (a group of pre-PhD researchers) the trip and estance. I talked about OpenMP again and some problemas with Dynamic Data structures, extending the previous work and trying to develop alternative and more efficient dynamic data structures.

Again, there were many other speeches both from my colleagues and from people of other universities.

This year the conferences were hosted in Coruña (Galicia, Spain), at Campus de Elviña. I was to Galicia 12 years ago and was glad to see the kind and warm character of people of Galicia is still alive

This year I wasn’t able to find an online official photo gallery, but I’ve uploaded my one

GCC Compiler “now” supports OpenMP

Actually, this isn’t recent news, since GCC supports OpenMP since version 4.2.0 (released on May, 2007). The interesting thing is that it’s being considered really stable and mature now; on the other hand, a new 4.3.0. branch is about to come. So we’ll soon see OpenMP support in our favourite Linux distro (it seems Fedora might already have included GCC 4.2.0 with OpenMP support already).

Previously, OpenMP support was done in GCC though the use of GOMP (an OpenMP library), but it has been finally merged into the developing mainline of this compiler collection (yes, Fortran have it too).

The specification implemented is OpenMP 2.5 (there’s a 3.0 draft on the way), and it seems to be completely supported, as you might read at the GCC Open MP features document.
