Application performance

As part of the ARCHER Knights Landing (KNL) processor testbed, we have produced and collected a set of benchmark reports on the performance of various scientific applications on the system. This has involved the ARCHER CSE team, EPCC's Intel Parallel Computing Center (IPCC) team, and various users of the system all benchmarking and documenting the performance they have experienced. 

Setting up your own Raspberry Pi cluster

Wee Archie: a wee bit of history

Wee ARCHIE Blue with Toy Pig Visitor

Some time ago (actually 2015), EPCC built a Raspberry Pi cluster called Wee Archie to demonstrate some of the principles behind a full-sized supercomputer. We designed the cluster to be portable as we can't carry around a real supercomputer and just looking at a laptop "connected" to some remote system isn't that engaging.

Global Challenges Research Fund: Research for Emergency Aftershock Response

Recent devastating earthquakes in Nepal and Italy have illustrated the need for better understanding and more accurate operational forecasting of aftershock sequences to assist emergency response. This project is a multi-disciplinary collaboration to develop risk assessments for earthquake aftershocks using dense networks of traditional seismometers, and to explore the use of mobile phones as sensors and for community engagement. 

Art from supercomputing

Last Thursday marked the opening of the FEAT project (Future Emerging Art and Technology) exhibition in Dundee’s LifeSpace art research gallery. The FEAT project is a pilot that focuses on the synergy between art and science, and how art can bring benefits to the scientific process. EPCC is involved through the INTERTWinE project.

For the past 12 months the artists Špela and Miha have been working with us on a piece related to supercomputing. They have spent time at a number of European supercomputing centres and additional FEAT workshops, such as the one in Vienna last summer that I attended and discussed in a previous blog article.

The Next Generation Sound Synthesis project (NESS) has concluded its five-year journey. With true inter-disciplinary focus, genuine user-engagement and over 75 publications overall, the project has been a great success for the University of Edinburgh, and for EPCC in particular.

Apple vs oranges: performance comparisons

Shall I compare thee...

Performance comparisons are always tricky to get exactly right. They are needed to ensure that we can demonstrate the performance improvements that optimisations, new hardware, new algorithms, etc... have had on an application or benchmark, but there is a lot of latitude in what can be compared, which makes it easy to get a performance comparison wrong and not properly demonstrate whatever it is you're trying to show.

Guest blogger Kara Moraw is an undergraduate Informatics student in Bonn, Germany. Here she writes about her 4-week internship with EPCC, spent working with EPCC's Nick Brown on the ARCHER outreach project.

EPCC PhD opportunity in micro-core architectures

At EPCC we are currently advertising a number of funded PhD opportunities (see our PhDs in HPC webpage). I am proposing a project entitled Improving the programmability of micro-core architectures, which builds on some of the work I first discussed in a previous blog post on ePython.

EPCC at the Edinburgh International Science Festival

EPCC will be at the Edinburgh International Science Festival again along with others from the University of Edinburgh. Last year we hosted a very successful Junkyard Clusters workshop where participants constructed a PC from its constituent components. This year we will be part of the drop-in activities, showing what supercomputers can do

Big Bang Fair: Day Three

Yesterday was Day Three of the Big Bang Fair, and it has kept delivering all the time. 

One of the most interesting things for me has been comparing this year to last year. For example, one of our most popular activities from last year, the supercomputing app, has been much quieter this year - but the beanbag sorting game has been a huge hit!
