This year’s European Geophysical Union General Assembly (EGU2013) was held last month at the Austria Center in Vienna.  About 11,000 participants come together from all fields in Earth science: seismology, oceanography, geology, meteorology, planetology… you name it, it’s there. So, lots of parallel sessions. I gave a presentation on iCORDI and the RDA at two sessions: ‘ICT-based hydrometeorology science and natural disaster societal impact assessment’ and ‘Marine Data Management’.

File transfer technologies for HPC systems

While a surprisingly high proportion of HPC users are happy to keep their data on a single HPC service, or at most to move it within the hosting institution, sometimes is becomes necessary to move large volumes of data between different sites and institutions. As anyone who has ever tried to support users in this endeavour knows, it can be much harder to get good performance than it should be. This post is an attempt to document the available tools and technologies as well as common problems and bottlenecks.

Simulation code usage on HECToR

What sort of research is the HECToR supercomputing facility used for and what simulation software does it make use of?

EPCC measures the use of different simulation codes used on the HECToR facility to get an idea of which codes are used most and what size of jobs different code are used for. In this post I will take a look at which codes are used most on the facility and speculate whether we can infer anything from the patterns we see.

Software optimisation papers for SC13

I've just finished working on two papers for this year's Supercomputing conference, SC13, which is going to be in Denver, Colorado, from the 17th-22nd November. EPCC will have an official presence, with an EPCC booth on the exhibition floor and a number of staff participating in the technical and education programmes. I thought this a good opportunity to write up some recent work I've been undertaking.

The CSC (IT Center for Science) in Helsinki could be said to be EPCC's equivalent in Finland, at least when it comes to the provision and support of high-performance computing services to academia and industry.
