In October 2014, a 2-day heavy rainfall event on the western coast of Norway caused major floodings. Hundreds of residents in the valleys around Flam needed to be evacuated, leaving houses, buildings and infrastructure severely damaged.

Research project TWEX was established to investigate such events in a future warming climate. The research answers questions such as: are the events more intense and what possible impact can we expect?

To assess these questions, research software engineers of the eScience Center performed simulations with the EC-Earth climate model of future high-precipitation situations. These simulations were used to drive hydrological models simulating the overflowing rivers along the Norwegian coast.

As a result, realistic future flooding scenarios for various river catchments were created, which may serve as a useful tool in guiding local authorities with their measures to adapt to a changing climate.

The ongoing corona crisis is impacting the research community in many ways. The eScience Center is also affected directly as the crisis is impeding some of the projects that are executed together with our research partners.

To ensure a proper continuation and conclusion of eScience projects delayed or impeded by the crisis, the eScience Center has adopted a flexible mitigation policy, as follows:

  1. For all ongoing eScience projects awarded in joint calls with the Netherlands Organisation for Scientific Research (NWO), the “Guidelines for ongoing projects as result of the corona crisis” (PDF) published by NWO on June 4, 2020 apply.

  2. For all ongoing projects awarded in eScience Center-only calls, the following guidelines apply:

    a. The starting date for projects for which the formal starting date expires before 31-08-2020 may be extended by up to 4 months. To be granted extension, the principal investigator (PI) must submit a request to the eScience Center.

    b. The submission of interim and final reports may be postponed by up to 4 months. To be granted postponement, the PI must submit a request to the eScience Center.

    c. Adaptations to the research plan, budget shifts or project extensions can be considered only if these alterations are budget neutral and do not change the primary research aims of the awarded project. The PI must submit a request for such alterations to the eScience Center.

  3. For all ongoing projects, also including eScience projects awarded in joint calls with NWO, any problems with the execution of the project, or the delivery of results, should be reported to the eScience Center.

    The eScience Center will consider incoming requests as soon as possible, typically within two weeks of submission. The aim is to respond to all requests under the above guidelines as flexible and accommodating as possible.


Formal requests and further questions

Formal requests for project alterations, as well as all further questions, must be sent directly to the eScience Coordinator associated with the project. The same message also must be sent to the Operations Department of the eScience Center (operations@esciencecenter.nl).

Interview door Steven Claeyssens

Graphics processing units (GPUs) have emerged as a powerful platform because they offer high performance and energy efficiency at relatively low cost. They have been successfully used to accelerate many scientific workloads. Today, many of the top500 supercomputers are equipped with GPUs and are the driving force behind the recent surge in machine learning.

However, developing GPU applications can be challenging, in particular with regard to software engineering best practices, and the quantitative and qualitative evaluation of output results. While some of these challenges, such as managing different programming languages within a project, or having to deal with different memory spaces, are common to all software projects involving GPUs, others are more typical of scientific software projects.

In their paper, Lessons learned in a decade of research software engineering GPU applications, the research software engineers (RSEs) address the challenges that they have encountered and the lessons learned from using GPUs to accelerate research software in a wide range of scientific applications.

“Many of the GPU applications used as case studies in the paper were developed as part of eScience projects at the Netherlands eScience Center”, says Ben van Werkhoven, research software engineer at the Netherlands eScience Center. “Programming GPU applications is a specialized field and while many scientists develop their own code, GPU research software is often developed by research software engineers (RSEs) that have specialized in this field. The goal of the paper is really to share our experiences, hoping that others can learn from our mistakes as well as our insights.”

Lessons learned

The researchers of the paper recommend to carefully select and if needed rewrite the original application to ensure the starting point is of sufficient code quality and is capable of solving the problem at the scale the GPU application is targeting. When performance comparisons of different applications are of interest to the broader scientific community it is important that RSEs can publish those results, both for the community to take notice of this result and for the RSEs to advance in their academic career.

According to van Werkhoven “The reason to move code to the GPU is often to target larger, more complex problems, which may require the development of new methods to operate at higher resolutions or unprecedented problem scales. GPU code can be implemented in many different ways, resulting in large design spaces with, for example, different ways to map computations to the GPU threads. As such, auto-tuning, with tools such as Kernel Tuner, is often necessary to achieve optimal and portable performance.

Evaluating the results of GPU applications often requires carefully constructed test cases and expert knowledge from the scientists who developed the original code. In eScience projects, these are often the project partners with whom we are collaborating.”

The software sustainability of GPU research software remains an open challenge as GPU programming remains a specialized field and RSEs are often only involved during short-lived collaborative projects.

According to Ben, they will continue to use GPUs in scientific projects and expect to continue to do so for a long time. Recently, several new supercomputers were announced and all the big machines include GPUs because of their high performance and energy efficiency. In addition, they plan to further advance and apply GPU auto-tuning technology.

The Netherlands eScience Center has changed the format of the scheduled information event for the eTEC 2020 and ASDI 2020 calls. Instead of a live online video streaming event, all the relevant information for both calls has now been made available on the eScience Center website.

This decision was made in order to give all participants equal access to all further information associated with the eTEC and ASDI calls. ‘Despite their immense value, video calls are often accompanied by technical issues that prevent some participants from receiving all the relevant information. We want to avoid such a situation and ensure an equal playing field for all potential applicants’, says Dr. Frank Seinstra, the eScience Center’s program director.

Advancing research through machine learning: an applied coding workshop

From 20 -24 January, the Netherlands eScience Center held a workshop on Machine Learning for Research at its offices at Amsterdam Science Park. 

During the workshop, which took place in a collaborative workspace, six teams from different disciplines and research institutions spent a week of hands-on work with machine learning experts from the eScience Center. Each team came equipped with their own data and went on to an intensive one-week collaboration with machine-learning experts from the eScience Center and SURF to explore the best machine learning strategy to tackle their research question.

The core focus of the workshop was on writing and developing code to analyze the data and apply suitable machine-learning techniques. This hands-on machine-learning experience was complemented by inspiring talks by the Director of the Netherlands eScience Center, Joris van Eijnatten, Maxwell Cai (SURF) on machine and deep learning, Vincent Warmerdam (GoDataDriven) on artificial stupidity, Jakub Tomczak (VU) on deep generative modeling and Florian Huber (eScience Center) on machine learning in research – dealing with the non-ideal.

“The workshop was a great experience. Together with my team, I got to actually focus on the research for 5 days without any interruption. The experts gave us enough time to work with our own data, providing us with good set of starting models we can refine. The talks were inspiring and informative. The trainers didn’t just explore the possibilities of machine Learning but also discussed its pitfalls.” – Eduard Klapwijk

“The best thing is we get to use our own data and work on our own problem instead of a hypothetical problem. It feels like we are actually getting somewhere instead of leaving the workshop with a very abstract view on machine learning tackling research problems” – Niala den Braber

“I was amazed by how motivated, persistent, and curious all teams were in exploring machine-learning options on all the great datasets they brought. Many participants started from a fairly basic understanding of machine-learning, but I really felt that their good knowledge about research and data allowed them to super quickly get a very good intuition about what machine-learning can and cannot do. I hadn’t expected that we would come that far in only one week.” – Florian Huber
