HPC Community Survey

Author: Guest blogger
Posted: 30 Mar 2016 | 17:23

This blog article comes from one of our current Phd students: Athina Frantzana, who is researching the obstacles facing women in the HPC community, and how equality can be improved.

The under-representation of women in STEM workforces has been a widely discussed subject in recent years. However, the recording and analysis of data regarding the gender balance of HPC remains rare.

Our study is a preliminary analysis of workforce and research participation in HPC, and aims to quantify the current level of representation of women in HPC and to provide a baseline for evaluating possible reasons and suggesting ways for future changes to the demographics.

Debugging in 5D

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.

Lancaster University, 7-8 April 2016

The programme for the HPC-CORE (High Performance Computing-based Computational fluid dynamics for Offshore Renewable Energy) workshop has now been published. This event brings together scientific specialists from Engineering, Atmospheric and Environmental Sciences, and HPC experts to discuss the state of the art for simulation software, and the leading-edge simulations being undertaken with such software.

We are very proud to be leading two new projects focused on the Exascale challenge: NEXTGenIO and INTERTWinE. Both started on October 1st 2015 and will run for 36 months.

A recent MSc project at EPCC has paved the way for improved diagnosis of eye-related conditions.

Adept Benchmark Suite released!

After a couple of years of measuring and trying to understand the power and energy consumption of (parallel) software and hardware, we have now released one of the key tools that we've been using as part of this research: the Adept Benchmark Suite!

While measuring performance (ie time to solution) is well understood, doing the same for power or energy is much less straightforward and often hardware dependent. The Adept Benchmark Suite relies on third party power measurement (such as instrumentation of the hardware) to be in place. However, to get users started with initial experiments, we provide a library to use RAPL (Running Average Power Limit) counters on Intel processors to measure the power of CPUs and memory, as well as some example code on how to use this library within the Adept Benchmarks.

ParCo 2015: the International Parallel Computing Conference

The International Parallel Computing Conference  (ParCo) was held in Edinburgh from 1st–4th September. ParCo2015 was the 16th instance of the series which started in 1983, making it the longest running series of international conferences in Europe on advances in the development and application of  parallel computing technologies.

HPC's role in Data Science

I was among those presenting at EPCC's recent Big Data seminars at Edinburgh BioQuarter and BioDundee. Both events provided a good opportunity for me to talk to people about their Big Data problems and their views on what Big Data means to them.

War in the coding world

It's not often that the internecine rivalries of the HPC research and development community spill over into the public arena. However, a video recently posted on YouTube (and the associated comments), ostensibly a light-hearted advert for a SC15 tutorial on heterogenous programming, shows how real and deep these rivalries can be.

Big Data: What's wrong with HPC?

Big Data vs HPC

Whilst I was writing my talk for last week's How to Make Big Data work for your business seminar at Edinburgh BioQuarter, it occurred to me that the way computational simulation codes have evolved over the last 40 years has really been a response to big data issues.
