INTERTWinE

Too much choice?

When is enough, enough? With so many parallel programming technologies, should we focus on consolidating them?

At the ISC conference in June I will moderate a panel discussion on whether it is time to focus on the consolidation and interoperability of existing parallel programming technologies, rather than the development of new ones.

Event Driven Asynchronous Tasks

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.

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.

A busy time at SC17

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.

Outlook good for exascale

Reaching the exascale has been a focus of the HPC community for several years, and EPCC has been a key player from the beginning.

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.

We are very proud to be leading two new projects focused on the Exascale challenge: NEXTGenIO and INTERTWinE. Both started on October 1st 2015 and will run for 36 months.
