Event Driven Asynchronous Tasks

Author: Nick Brown
Posted: 5 Apr 2018 | 10:28

The INTERTWinE project has spent a lot of effort addressing interoperability challenges raised by task-based models. By rethinking parallelism in the paradigm of tasks, one reduces synchronisation and decouples the management of parallelism from computation.

This is really attractive but existing models typically rely on shared memory, where the programmer expresses input and output dependencies of tasks based upon variables, which in turn limits the technology to a single memory space – often a node of an HPC machine. So to then scale up beyond a single memory space we must combine a task model with distributed memory technology, such as MPI or GASPI, and this has been a focus for a number of activities in INTERTWinE.

Here at EPCC we are looking forward to the 5th Exascale Applications and Software Conference (EASC 2018), which will be held here in Edinburgh in a couple of weeks. This will be the third time we have hosted EASC and it is always a great opportunity to hear about  the cutting edge of HPC research.

EPCC is hiring data scientists

At EPCC we are currently looking to hire both Application Developers and Application Consultants in data science (closing date 22nd of February.) I think this is a really great opportunity for people to become involved in an exciting, fast moving field with great potential and EPCC is a major player in this area.

Our situation in the University makes us fairly unique. We have a diverse mix of both research and commercial projects so it is possible to work on developing the state of the art and also with some big names on work that has a real-world impact. Unlike many technical/research positions at the University, which are short-term Post-Docs, at EPCC our positions are longer term (initially a 2-year fixed-term contract) and many staff have been working at EPCC for several years.

INTERTWinE project presented at collaboration workshop in Japan

Last month I attended a collaboration workshop in Japan between the Centre for Computational Sciences (CCS) at the University of Tsukuba and EPCC. I was talking about the INTERTWinE project, which addresses the problem of programming-model design and implementation for the Exascale, and specifically our work on the specification and implementation of a resource manager and directory/cache.

I am at SC 17 in Denver this week and having a really busy (but fun) time, giving some talks and catching up with people in the HPC community.

The Natural Environment Research Council (NERC) will run its showcase event at Dynamic Earth entitied UnEarthed from 17th-20th November. This will be a chance for the general public to interact with over thirty exhibts from all over NERC's science remit and to understand how UK scientists are answering some of the biggest questions on Earth.

Nick Brown and Wee Archie, our Raspberry PI mini super-computer, went to Boston in February for the annual American Association for the Advancement of Science (AAAS) meeting. 

Art from supercomputing

Last Thursday marked the opening of the FEAT project (Future Emerging Art and Technology) exhibition in Dundee’s LifeSpace art research gallery. The FEAT project is a pilot that focuses on the synergy between art and science, and how art can bring benefits to the scientific process. EPCC is involved through the INTERTWinE project.

For the past 12 months the artists Špela and Miha have been working with us on a piece related to supercomputing. They have spent time at a number of European supercomputing centres and additional FEAT workshops, such as the one in Vienna last summer that I attended and discussed in a previous blog article.

EPCC PhD opportunity in micro-core architectures

At EPCC we are currently advertising a number of funded PhD opportunities (see our PhDs in HPC webpage). I am proposing a project entitled Improving the programmability of micro-core architectures, which builds on some of the work I first discussed in a previous blog post on ePython.

This week I will be going to Boston for the American Association for the Advancement of Science (AAAS) annual meeting. This brings together scientists & engineers, not only from the US but the entire world, to discuss the latest developments in the field.
