Selfish performance

Sharing of resources has challenges for the performance and scaling of large parallel applications. In the NEXTGenIO project we have been focusing specifically on I/O and data management/storage costs, working from the realisation that current filesystems will struggle to efficiently load and store data from millions of processes or tasks all requesting different data sets or bits of information.

Exploring I/O

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.

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.

NEXTGenIO: a step towards Exascale

The NEXTGenIO project represents a step along the Exascale pathway.

We are developing a prototype platform that utilises the latest developments in memory technology, and that will offer vastly improved I/O performance compared to current HPC machines. The system will be developed end-to-end by the project partners – from inception through to delivery, with a full suite of systemware that can make use of the new technologies.
