Or why debugging is hard and parallel debugging doubly so

Debugging programs is hard. I give a lecture on debugging for the Programming Skills module of EPCC's MScs in HPC and HPC with Data Science where we try to point out common programming mistakes, programming strategies for making bugs less likely, and the skills and tools required for investigating, identifying, and fixing bugs.

Next month, a group of EPCC staff members will be travelling to Birmingham to take part in The Big Bang Fair 2016, a national science festival for school children. The event takes place over four days and will reportedly attract in excess of 70,000 visitors, so this is a great opportunity to showcase ARCHER, EPCC and all of the work we do here.

The Collaborations Workshop (CW) is coming home to Edinburgh. It will be held on 21st-22nd March in the Royal College of Surgeons with an optional hack day on 23rd of March.  The series of CWs were originally started under the now defunct Open Middleware Infrastructure Institute UK (OMII-UK) that held two workshops in Edinburgh in 2009 and 2010 in what was then the National e-Science Institute in Edinburgh. The aim of these workshops was to get researchers to come together, talk, avoid reinventing the wheel and to establish fruitful collaborations. It was, and has remained, a most excellent networking event.
