MemAxes: Visualization and Analytics for Characterizing Complex Memory Performance Behaviors

Wednesday, August 30th, 2017

A new publication in the journal: IEEE Transactions on Visualization and Computer Graphics by our senior lecturer Ilir Jusufi about High-Performance Computing memory performance analysis through the use of Visual Analytics.

Abstract: Memory performance is often a major bottleneck for high-performance computing (HPC) applications. Deepening memory hierarchies, complex memory management, and non-uniform access times have made memory performance behavior difficult to characterize, and users require novel, sophisticated tools to analyze and optimize this aspect of their codes. Existing tools target only specific factors of memory performance, such as hardware layout, allocations, or access instructions. However, today’s tools do not suffice to characterize the complex relationships between these factors. Further, they require advanced expertise to be used effectively. We present MemAxes, a tool based on a novel approach for analytic-driven visualization of memory performance data. MemAxes uniquely allows users to analyze the different aspects related to memory performance by providing multiple visual contexts for a centralized dataset. We define mappings of sampled memory access data to new and existing visual metaphors, each of which enabling a user to perform different analysis tasks. We present methods to guide user interaction by scoring subsets of the data based on known performance problems. This scoring is used to provide visual cues and automatically extract clusters of interest. We designed MemAxes in collaboration with experts in HPC and demonstrate its effectiveness in case studies.

Workshop on How to write Impact in a Horizon 2020 proposal – maximizing funding success by using market research

Monday, August 28th, 2017

When: 20 September 2017 at 10:00 – 12:00

Where: Homeros VF115 Hus F, Växjö

Impact has become one of the key evaluation criteria in Horizon 2020-proposal. Sometimes it is hard to grasp the concept of ‘Impact’ and to explain the potential impact of the proposals. When writing a proposal for the Horizon 2020 – programme, it is important to remember that you are not alone, there are several researchers from all over Europe submitting proposals. This means that your proposal is in hard competition with other scientists/researchers/universities for the same financing. More than anything else, you must convince the evaluators (only through a one proposal) that you are the one the EC should finance. One way to do this is to write a really convincing the impact section. The aim of this Impact WS is to explain the concept of ‘impact’ and provide researchers and research support staff with guidelines on writing the impact part of Horizon 2020 proposals by using market research.

The speaker, Mr Lance Leverette, an Industrial Market Analyst, has been active in EU funded proposals and works with both academics and SME’s in UK, Spain, Slovakia and Greece. Lance is working across several sectors such as water technologies, advanced materials and manufacturing, and medical devices. In his presentation he will discuss the differences in methodologies, how to understand the commercial value of research, how to chart a path to the market, and how these can be worked into the H2020 proposal and project. The session will give participants the framework for addressing impact for Pillars 2 and 3, particularly in terms of exploitation of the project results.  Understanding US framework for commercialization of research is also very valuable providing growing interest for the collaboration with US colleagues within H2020 and beyond. Workshop will be held in English.

3rd annual Big Data Conference at Linnaeus University

The conference this year is hosted by Linnaeus University Centre for Data Intensive Sciences and Applications (DISA). We have invited researchers from our own Centre to present some of the work that has taken place within DISA this past year and Keynote and invited talks from other universities.

First invited talk: 

Kristoffer Laigaard Nielbo, Associate professor at Aarhus University

The research by Kristoffer Laigaard Nielbo covers two areas of interest of which one is more recent (automated text analysis) and the other (modeling of cultural behavior). Both interests explore the cultural information space in new and innovative ways by combining cultural data and humanities theories with statistics, computer algorithms, and visualization. We feel honored to welcome Kristoffer Laigaard Nielbo to the conference since one of our focus areas within DISA is Data-Intensive Digital Humanities.

When? Friday December 1st 2017, at 9.30-16.00

Where? Linnaeus University, Building: N, Room: IKEA

Registration will open in September, keep your eyes open for more information

New research opportunities with Södra.

Monday, August 14th, 2017

During late spring 2017, guest researcher Andreas Heberle spent some weeks to learn more about the needs and opportunities for joint research between Södra and tour DISA researchers. During these months Andreas has interviewed several domain experts at Södra and he found over 50 ideas and opportunities that could be the base for joint research.

Just before the summer holidays started, DISA researchers and experts from Södra gathered for a follow up workshop to discuss the potential next steps. The experts from Södra got the list with 50 ideas down to seven that were the most prioritized for them and in discussion with the researchers the list went down to three ideas/opportunities. Many of the other ideas will be taken care of internally at Södra. We have responsible people for each idea and looking forward to see some concrete action, either as full research projects or as student projects in one form or another.

We will by this show that there are many different ways to work together and it is by talking we can find out what works best for us within DISA and for you who wants to work closer with us. If you have ideas for joint research – don’t hesitate to contact us.


Kick-off for DISA-researchers August 22

Thursday, August 10th, 2017

Welcome back after a nice long summer holiday!

Our Linnaeus University Center – DISA has been up and running for about seven months now and a lot has happened, several workshops with researchers from different disciplines, with external partners, new publications, submitted proposals and much more.. Everyone’s been busy with getting things up and running so we haven’t had a proper kick-off – but now its time.

A warm welcome to all researchers involved in DISA to join in for our Kick-off

When? Tuesday August 22 at 15.00-17.00

Where? Videum Science Park, Växjö. Building: Echo

For more information and to register see attached invitation.

See you soon!
