Can one of our MSc students help you?

We're looking for collaborative projects with industry and academia.

A new batch of students will soon be joining our MSc in High Performance Computing (HPC) and MSc in HPC with Data Science.

As ever we are on the look-out for interesting collaborative projects for the students to undertake towards the end of their course (roughly from April/May to August). 

MPI performance on KNL

Knights Landing MPI performance

Following on from our recent post on early experiences with KNL performance, we have been looking at MPI performance on Intel's latest many-core processor.

MPI ping-pong latency on KNC and IvyBridge
Figure 1

The MPI performance on the first generation of Xeon Phi processor (KNC) was one of the reasons that some of the applications we ported to KNC had poor performance.  Figures 1 and 2 show the latency and bandwidth of an MPI ping-pong benchmark running on a single KNC and on a 2x8-core IvyBridge node.

EPCC loves active travel!

Proof that whilst EPCC may be one of the nerdiest enclaves in the University, we sure aren't all couch potatoes.

When local cycle campaign group Spokes released their latest edition of the Edinburgh Pedestrian and Cycling Route map, several of us agreed it would be an excellent idea to have a copy on the coffee room wall, to help plan trips around town and encourage new cyclists, or help current cyclists explore new areas.

Data and Software Carpentry combo at Edinburgh

With my Software Sustainability Institute hat on, I recently participated in a back-to-back Data Carpentry and Software Carpentry course sponsored by the University's Research Data Service here at the University of Edinburgh. The courses were held in the main University library in a gorgeous room with a glass wall, providing a rather distracting view of the Meadows parkland. 

​A not-so-brief history of research software engineers

This guest post by Simon Hettrick, Deputy Director of the Software Sustainability Institute, explains how the role of research software engineer has gained greater definition and recognition.

On a beautifully sunny day in March 2012, a small group met at Queen’s College Oxford and challenged a long-standing problem: why is there no career for software developers in academia? They didn’t know it at the time, but this meeting led to a nationwide campaign that created a vibrant and rapidly growing community, and established a new role in research: the Research Software Engineer.

Summer of HPC: Finding the fireball

Summer of HPC visitor Tomislav Subic gives a summary of his project at EPCC: a visualisation of the UK Met Office's weather model.

A legend says that there was once a warm sunny day in Scotland. I have started my quest to find out if the myth was true, but I was not the only one.

Forthcoming computational biomolecular research events

BioExcel is a newly launched Centre of Excellence that helps academic and industrial researchers to use high-performance computing and high-throughput computing in biomolecular research. 

We are running a number of events in September and October and I would be very grateful to anybody who circulates these to people or groups that may be interested (and bonus points if you are willing to share with me details of where/to whom you publicise so that we can reduce cross-posting).

 

Summer of HPC: Scotland for the summer, seriously?

 Summer of HPC visitor Tomislav Subic writes about his introduction to Edinburgh and EPCC.

“It’s gonna be cold and rainining up there the whole time…”

If I got a pound every time I heard that in the last months, I could buy a kilt (which are not cheap by the way). While most of my fellow SoHPCers are fleeing the north in order to spend their summer on the sunny Mediterranean beaches, I am doing the opposite.

Early experiences with KNL

Initial experiences on early KNL

Updated 1st August 2016 to add a sentence describing the MPI configurations of the benchmarks run.
Updated 30th August 2016 to add CASTEP performance numbers on Broadwell with some discussion

EPCC was lucky enough to be allowed access to Intel's early KNL (Knights Landing, Intel's new Xeon Phi processor) cluster, through our IPCC project.  KNL Processor Die

KNL is a many-core processor, successor to the KNC, that has up to 72 cores, each of which can run 4 threads, and 16 GB of high bandwidth memory stacked directly on to the chip.
