Dr Elsa Gonsiorowski is visiting EPCC from Lawrence Livermore National Laboratory, California, this week. Dr Gonsiorowski is working closely with EPCC's David Henty on various parallel I/O research topics. In this post she introduces her work.

Planning for high performance in MPI

Many HPC applications contain some sort of iterative algorithm and so do the same steps repeatedly, over and over again, with the data gradually converging to a stable solution. There are examples of this archetype in structural engineering, fluid flow, and all manner of other physical simulation codes.

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.

Top500: Change or no change?

November 2017 Top500

My initial impression of the latest Top500 list, released last month at the SC17 conference in Denver, was that little has changed. This might not be the conclusion that many will have reached, and indeed we will come on to consider some big changes (or perceived big changes) that have been widely discussed, but looking at the Top 10 entries there has been little movement since the previous list (released in June).

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.

Deep Learning at scale: SC17 talk

Are you interested in using machine learning for something big enough to need supercomputing resources?

Have you worked on, or with, one of the Deep Learning frameworks, like TensorFlow or Caffe?

Are you just curious about the state-of-the-art at the crossover between AI and HPC?

View from the storage side

Flash Memory Summit Logo

I recently attended the 2017 Flash Memory Summit, a conference primarily aimed at storage technology and originally based around flash memory, although it has expanded to cover all forms of non-volatile storage technology.

Non-volatile memory is a big deal nowadays.  It is memory that stores data even when it has no power (unlike the volatile memory in computers that lose data when power is switched off).  Flash memory is a particular form for non-volatile memory, it's been used for a long time, and has had a massive impact on consumer technology, from the storage in your cameras and phones, to SSD hard drives routinely installed in laptop and desktop systems.

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