Building design has been revolutionised in recent years. New materials and better construction techniques have allowed bespoke and impressive public spaces to be created. Consider the Millennium Dome, Hong Kong airport, or the 2012 Olympic stadium.
These bespoke spaces represent a significant challenge for fire safety. Unlike for conventional buildings, with regular layouts and dimensions, there is very little experience to suggest how fires might develop in these spaces, and how people might react in an emergency situation.
An Edinburgh-led consortium, called FireGrid, is developing technology designed to tackle this specific problem head-on. By combining advanced modelling with sensor data, in a high performance computing (HPC) context, the FireGrid team are developing a system that can provide fire fighters with better information to support their response, to control the impact of a fire emergency, and to reduce the risk to life and property.
In this talk we will review progress of the FireGrid consortium and describe a technology prototype that has been built to demonstrate the potential for such a system, and to stress some of the key technologies that are required.
This talk was given as part of our MSc in HPC's 'HPC Ecosystem' course.

Adventures in the Biology trade : Bioinformatics in the Petabyte era (60 mins, ~42 MB) 1:00:00

11 years тому1:00:00

1:00:00

Bioinformatics and more widely Computational Biology is a largely data-driven Science. The array of high-throughput technology platforms in the last 10 years mean that the amount of data being generated in this field is likely to enter into Exabytes by 2020. The challenges associated with this are quite different from the data sets generated by High Energy Physics or Astrophysics in that they tend to gathered from a wide variety of different providers. Meta-analyses of these data sets can give startling new insights but come with many caveats - in particular that the quality of the data from each provider can be highly variable. I will spend some time talking about one set of experiences I have dealing with one specific technology platform and in particular how it is clear that the detection of bias in data sets is a key element of any high-throughput analysis. This talk was given as part of our MSc in HPC's 'HPC Ecosystem' course. Talk slides…

Solar analysis - the journey from two weeks to one hour with HPC (38 mins, ~24 MB) 38:00

11 years тому38:00

38:00

Performing complex solar shading analysis to take into account the sun's path and solar penetration on large buildings has historically consumed very many CPU cycles for IES "Virtual Environment" (3D building physics) simulation users. One particularly complex model took almost 2 weeks to process. A description of the collaboration between IES and EPCC to apply HPC practices to the solar analysis algorithm and benchmark results will be presented. Additionally we will cover the pitfalls found when integrating the MPI solution in a commercial environment and how we addressed these. The presentation will conclude with a brief description of in-progress and potential future developments with EPCC. This talk was given as part of our MSc in HPC's 'HPC Ecosystem' course.

The Power of Many: Running Many Simulations on Many : Dr. Shantenu Jha, Rutgers University (57 mins, ~28 MB) 57:00

57:00

There are several important science and engineering problems that require the coordinated execution of multiple high-performance simulations. Some common scenarios include but are not limited to, "an ensemble of tasks", "loosely-coupled simulations of tightly-coupled simulations" or "multi-component multi-physics simulations". However, historically supercomputing centers, have supported and priortised the execution of single "jobs" on supercomputers. Not suprisingly, the tools and capabilities to support coordinated multiple simulations are limited. A promising way to overcome this common limitation is the use of a Pilot-Job --- which can be defined as a container or placeholder job to provide multi-level scheduling via an application-level scheduling overlay over the system scheduler. We discuss both the theory and practise of Pilot-Jobs: Specifically, we introduce the P* Model of Pilot-Jobs and present "BigJob" as a SAGA-based extensible, interopable and scalable implementation of the P* Model. We then discuss several science problems that have/are using BigJob to execute multiple simulations at unprecedented scales on a range of supercomputers and distributed supercomputing infrastructure such as XSEDE.

This talk will look at the drivers leading the way to Exascale computing. It will examine technology trends, and use these to infer some of the characteristics of future large scale HPC systems. It will also look in to what this means for the software environment, reliability, use and affordability of IT systems at the high end. Recently, the IT industry has become more focused on problems involving the use and management of large data sets (Big Data) and we map this trend on to the consequences of Exascale computing. What will future architectures look like, how will they be used, and what does that mean for applications development today? This talk was given as part of our MSc in HPC's 'HPC Ecosystem' course.

GPU Computing: Past, Present and Future (47 mins, ~21 MB) 47:00

13 years тому47:00

47:00

The past five years have seen the use of graphical processing units for computation grow from being the interest of handful of early adopters to a mainstream technology used in the worldâ€™s largest supercomputers. The CUDA GPU programming ecosystem today provides all that a developer needs to accelerate scientific applications with GPUs. The architecture of a GPU has much to offer to the future of large-scale computing where energy-efficiency is paramount. NVIDIA is the lead contractor for the DARPA-funded Echelon project investigating efficient parallel computer architectures for the exascale era. Timothy Lanfear is a Solution Architect in NVIDIAâ€™s Professional Solutions Group, promoting the use of the NVIDIA Tesla(TM) computing solution for high-performance computing. He has twenty yearsâ€™ experience in HPC, starting as a computational scientist in British Aerospaceâ€™s corporate research centre, and then moving to technical pre-sales roles with Hitachi, ClearSpeed, and most recently NVIDIA. He has a degree in Electrical Engineering and a PhD for research in the field of graph theory, both from Imperial College London. Talk slides…

There is a plethora of version control systems and it is not obvious which to choose. Do you pine for the warm, comforting blanket of CVS? Fear not! I shall give an overview of the zoo of version control systems available to the modern programmer. I'll describe the design principles (there is much overlap) and how these influence the use patterns. I hope to convince you that modern systems are at least as good as CVS and Subversion, and to indicate some of the areas in which they make a programmer's life much, much easier.

Fluidity: an adaptive, unstructured mesh CFD framework. Applications, software development methods and parallel performance: Dr Jon Hill, Imperial College London (48 mins, ~22 MB) 48:00

14 years тому48:00

48:00

Fluidity is a powerful Computational Fluid Dynamics framework developed at Imperial College over the last 20 years. Fluidity can be applied to a number of scientific applications, ranging from classic CFD, to oceans and multi-material problems. It uses a variety of discretisations on an unstructured mesh and includes a number of novel and innovative features, such as adaptive re-meshing, a user friendly interface, and a python interface. The main advantage Fluidity has is the adaptive re-meshing, which allows resolution to be focused where and when it is required during a simulation, depending on the simulation state at that time. This talk will briefly cover some of the features and science behind Fluidity before covering details of AMCGâ€™s software development methodologies and the parallel scaling behaviour of Fluidity on HECToR. Finally, future developments will be covered. Links: Slides - Talk slides…
