HPC-Europa 3 visit: Optimising the processing of food

Miriam Ruiz Ferrández was a recent HPC-Europa3 visitor to Edinburgh who used EPCC resources while being hosted by Napier University. In this article she relates some of her findings and experiences.

Hi everyone! I am a PhD student at the University of Almería, which is located in the south-east of Spain. I spent three months in Edinburgh funded by the HPC-Europa3 programme working on a project entitled: “A Parallel Multi-Objective Algorithm for Optimizing High-Pressure/Temperature Treatments in the Food Industry”. During this research stay, I was collaborating with Professor Ben Paechter at Edinburgh Napier University and I used computing resources provided by EPCC at the University of Edinburgh.

Outreach: Planes, zombies, chickens and bean bags

Zombie Chickens - Attributed to B Zedan (CC BY-NC-SA 2.0 - https://www.flickr.com/photos/bzedan/960200896/)Wait a minute – isn't this a blog article for EPCC ? One of the premier HPC centres in Europe, where are zombies and bean bags coming from?

Frequent readers of our blog may have twigged that this is another article about our outreach efforts at EPCC. A few weeks ago we were in Birmingham for the Big Bang Fair 2018 (one of the largest science events  for schools held in the UK) and at the beginning of April, EPCC was once again part of the Edinburgh International Science Festival.

Event Driven Asynchronous Tasks

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.

Exascale Applications and Software Conference (EASC 2018)

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.

EPCC at Data Science Festival

EPCC took part in Datafest18, the Data Science Festival, this year by running our own fringe event in Edinburgh and exhibiting at the Data Summit Conference.

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.

Big Bang Fair 2018: a success!

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.

HPC-Europa3 visit: detecting floating objects in the sea using aerial images

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).

Installing Python packages in virtual environments

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 pip or 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.

Big science! EPCC at the EISF 2018

EPCC will be at the Edinburgh International Science Festival (EISF) from Saturday March 31st until Wednesday April 4th with our exhibit Doing Big Science on Supercomputers.

The show must go on: extreme weather at the ACF

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.
