Today I attended the "First International Workshop on Energy Efficient Supercomputing (E2SC)"

It was really interesting (and confidence boosting) to find that what we are trying to do in the Adept project is similar in approach to that done by other research labs. The talks could be divided into two categories: modelling the effect of system parameters (such as cache) on energy and performance efficiency; and methods for measuring energy consumption.

CP2K user meeting: overcoming the 'complexity hump'

For the last five years, I've been involved in the development of the CP2K materials science code, mostly in terms of improving its performance and scalability and porting to new systems. During that time a great deal of new functionality has been added, as well as additional input file options, libraries and autotuning capability to enable maximum performance on any given architecture. However, these improvements have come at the cost of increased complexity - and CP2K already has a fearsome reputation among researchers for being very hard to use!

As the title says, "Hello Denver".

This is my first time in Denver and thanks to a grant from UKUSAHPC, I'm attending SC13. Over this next week, I'll  share some insights from SC about what's happening in the area and any especially interesting people I meet.

EUDAT - the European Data Infrastructure project - has reached the end of its second year and has, with some success, distilled the first version of a common, collaborative, horizontal data infrastructure from among the vertical stacks of its various partners.
