The INTERTWinE project has spent a lot of effort addressing interoperability challenges raised by task-based models. By rethinking parallelism in the paradigm of tasks, one reduces synchronisation and decouples the management of parallelism from computation.
This is really attractive but existing models typically rely on shared memory, where the programmer expresses input and output dependencies of tasks based upon variables, which in turn limits the technology to a single memory space – often a node of an HPC machine. So to then scale up beyond a single memory space we must combine a task model with distributed memory technology, such as MPI or GASPI, and this has been a focus for a number of activities in INTERTWinE.

Here at EPCC we are looking forward to the 5th Exascale Applications and Software Conference (EASC 2018), which will be held here in Edinburgh in a couple of weeks. This will be the third time we have hosted EASC and it is always a great opportunity to hear about the cutting edge of HPC research.

Fringe events are key to the success of Datafest, and with over 40 running across Scotland there was plenty to choose from. We ran a small event to deliver key insights on the new developments in the application of supercomputing to large-scale data analytics and machine learning. Our colleagues gave a series of talks and attendees also had an opportunity to see a live supercomputer in action via Wee Archie. The event allowed for plenty of questions and in-depth conversations, notably around deep learning and using neural networks to solve real-life problems. It closed with Dr Adam Carter providing some further details on what makes a data scientist, and the various routes to development and further training.

For the third year running a group of us from EPCC attended the Big Bang Fair (BBF) at the NEC in Birmingham through the ARCHER Outreach programme. BBF provides an excellent opportunity to show a wide range of young people what supercomputing is about and encourage them to adopt careers in STEM-based subjects.
We are writing our activities up to encourage others to try doing supercomputing outreach and show that you do not need fancy equipment. For more information see the ARCHER's Ambassador pack or GitHub where we develop these. We enourage you to feedback or collaborate with us.

Dr Antonio Javier Gallego visited EPCC under the HPC Europa 3 Programme. He recounts his experiences in this blog article.
My name is Antonio Javier Gallego and I am from Alicante, Spain. I visited EPCC under the HPC-Europa3 programme hosted by Prof. Robert 'Bob' Fisher at The University of Edinburgh's School of Informatics. My research project consisted of the development of methods for the detection of floating objects in the sea from aerial images. In particular, two methods were proposed: one for the detection of oil spills and another for locating people in the sea (ie drowned, shipwrecked, or fallen overboard).

I recently looked into whether the Python package PyQt5 could be installed on Cirrus, a Tier-2 national service, on behalf of one of our HPC Europa visitors. The Cirrus documentation recommends that you do this using virtual environments and provides a helpful example. However, the problem is that if you subsequently use
easy_install to install additional Python packages within the virtual environment you will get a permission denied as it tries to install the package centrally to directories you do not have access rights to. I eventually managed to find a solution.

On Wednesday 28th February, Edinburgh and the Central Belt of Scotland saw an unprecedented volume of snow fall in a short space of time. Around late morning that day, the Scottish Transport Minister Humza Yousaf unexpectedly upgraded the extreme weather warning from Amber to Red from 15:00 on 28th February, suggesting widespread damage, travel and power disruption, and a risk to life were likely.

This is a very exciting time for the MSc in HPC programmes. Our current students are halfway through their second semester of courses and are already starting work on developing their dissertation projects, while EPCC staff are looking forward to our summer move into the new Bayes Building. Located in the University's central area, this move will strengthen our existing collaborations with the School of Informatics.
