Diversifying the HPC Community

The eighth international Women in HPC workshop will be held at ISC18, Frankfurt, Germany. This workshop provides leaders and managers in the HPC community with methods to improve diversity and also to provide early career women with an opportunity to develop their professional skills and profile. Following the overwhelming success of the 2017 WHPC workshops we will once again discuss methods and steps that can be taken to address the under-representation of women, in particular by discussing the following topics:

  • How to build workplace resilience and maintain well-being, while managing work stress.
  • Being part of the solution: instructions for advocates and allies.
  • Best practices from organizations on improving workplace diversity.
  • Managing the two body problem and achieving effective work-life balance.

We will also provide opportunities aimed at promoting and providing women with the skills to thrive in HPC including:

  • Short talks by women working in HPC
  • Pointers on how to handle workplace conflicts and effectively respond to discrimination
  • Short talks on: best practices from equity frameworks from outside HPC, suggestions and challenges for women in HPC related venture capitals, effectively dealing with workplace discrimination, building a successful career, excelling in the workforce, etc.

Abstract: Performance Analysis of GS2 Plasma Turbulence Code

We will present the work done to analyse and recommend improvements to the GS2 plasma fusion code performed under the Performance Optimisation and Productivity (POP) Centre of Excellence. GS2 is a gyrokinetic flux tube initial value and eigenvalue solver written in Fortran and parallelised with MPI. Barcelona Supercomputing Center performance analysis tools Extrae and Paraver were used to analyse the performance of GS2 and calculate the POP metrics which are discussed. The work shown is a comparison of two different ways to decompose the data across MPI ranks: the existing default and a decomposition suggested by previous performance analysis. We see that the new method of decomposing the data results in a significantly improved runtime which is mainly due to a reduction in the amount of data transferred due to an improved communication pattern.

Abstract: The movement towards HPC inclusivity: Achieving on-demand accessibility of High Performance Computing (HPC) in single-user, ephemeral projects through the Alces Gridware Project

In the past two years High Performance Computing (HPC) has evolved from a specialised field to a more diverse and inclusive arena. Specifically, through public cloud. This impact provides institutions ‘hybrid HPC capabilities,’ dropping time to science dramatically depending on project size and integration methods. Through the open-source Alces Gridware project we created Alces Flight Compute, a fully-featured, scalable HPC environment for research and scientific computing. A free version was created for cloud and hybrid use to understand how an individual researcher would approach and consume on-demand HPC resource regardless of platform. Over eighteen months leaders in manufacturing, medicine, genomics, mapping, and research universities have collaborated with Alces to ascertain a broader understanding of trends, success, and barriers that exist in creating HPC environments conducive to diverse research.

Our initial results show: – Acquisition of public cloud over traditional HPC server time is startlingly quick, with a current average time of a day and a half, including training. – Those experiencing barriers to entry for cloud were primarily due to economic or knowledge reasons, not technical. – Ephemeral (temporary) cloud workloads that are embarrassingly parallel work best with auto-scaling HPC clusters, in one case saving 64% on operational costs. – In the case of hybridisation clients primarily utilise resources which might be cost prohibitive in an on-premise design, ex. GPUs and FPGAs. – Creation of a consistent environment across platforms, while obfuscating the location for the end user, yields higher levels of user acceptance and optimisation.

Abstract: Parallel Password Cracker

Passwords are one of the most important forms of authentication. They can be found in all walks of life: ATMs, social networks, e-services, etc. Usually, passwords are stored as hashcodes, rather than plain text, in databases by using a special hashing algorithm to protect them. Password cracking is a process of recovering passwords from data that have been stored in the system. A common approach is to try to guess repeatedly for the password and check against an available cryptographic hash of the password.
The strength of a password depends on its length and diversity of character types. The more characters that make up a password, the larger number of possible passwords.
A parallel computer can be used to crack passwords. It can do more calculations per second, allowing users to make more password guesses per second. This work helps people have insights into information security and demonstrates how parallel computing is used to shorten the password cracking time. It can help users create safer passwords.

Abstract: DYNAMO – Dynamic Analysis Modelling and Optimisation of GDI engines

DYNAMO (Dynamic Analysis Modelling and Optimisation of GDI engines) is an R&D project co-sponsored by the Advanced Propulsion Centre – APC6 Call. In collaboration with Ford Motor Company (Project Lead) and six other UK based partners – Loughborough University, Bath University, Siemens CDA, Hartree Centre, Cambustion, DE&TC. The project aims to significantly improve the fuel efficiency of two high volume passenger vehicle powertrains with specific intent to simultaneously reduce CO2 and noxious emissions. Modern, fuel efficient Gasoline Direct Injection (GDI) engines have been shown to actually emit more particulate than diesel engines. Worryingly, GDI engines emit particulate matter mostly in the ultra-fine size range, where current tail-pipe gas filters show low filtration efficiency. This has serious environmental consequences and health implications. (1)

During the project the team helps to develop and mature new and upgraded advanced engine technology ready for commercialisation and aims to revolutionise the process and methodology currently used to design and develop complex powertrains. It will demonstrate an analytical approach which enables multiple engine systems to be optimised to multiple objectives in parallel and under transient conditions to improve legislated and real world fuel economy, whilst drastically reducing development time and costs.(2)
High Performance Computing (HPC) allows scientists and engineers to solve complex, compute-intensive problems efficiently. Hartree centre is supporting the project with HPC facilities and optimising the end results.

Abstract: High-volume data processing for ambient healthcare research prototyping

The SPHERE project continues to deploy multimodal sensor networks into dozens of homes in the South West of England. The resulting dataset is expected ultimately to be large enough to significantly complicate reprocessing using the methods developed during the prototype phase of SPHERE, which were designed in the expectation that they would be deployed locally to each home. Therefore, various alternative means for processing the data are considered, including distributed indexing execution. For reasons of confidentiality and pragmatism, the use of public cloud platforms is not appropriate. The University of Bristol’s HPC facility, Bluecrystal, will be used for this purpose.

We are currently in the process of adapting our existing processing pipelines to the platform. Once this is complete, we expect the increase in processing speed and parallelism to permit us to compare the behaviour of several machine learning approaches across the dataset. Where practical, the most successful methods will eventually be adapted to run on the sensor platforms themselves.
