Wee Archie is our mini-supercomputer made from Raspberry Pis, used for public outreach to teach members of the public the concepts of supercomputing. It has been very successful, and as such a second one has been built to keep up with demand!

The Student Cluster Competition is held three times a year, at Supercomputing, ISC High Performance and the Asia Student Supercomputing Challenge. EPCC has taken part in the past with great success and we're returning to the competition at ISC17 with a strong team of students from our MSc in High Performance Computing, and MSc in High Performance Computing with Data Science.

When we parallelise and optimise computational simulation codes we always have choices to make. Choices about the type of parallel model to use (distributed memory, shared memory, PGAS, single sided, etc), whether the algorithm used needs to be changed, what parallel functionality to use (loop parallelisation, blocking or non-blocking communications, collective or point-to-point messages, etc).

This article covers what I think is a good way of taking notes, keeping track of them, and publishing them so that others can benefit from them or comment on your approach.
We often use notes to track what we have to do or have done. They might be in paper form or electronic text files. They document how we achieved our goal: the helpful URLs that put us on the right track, error and warning messages that were encountered and how they were resolved, etc. However, notes can quickly become intractable with recorded error and/or warning messages and unfathomably long URLs or, worse, they get lost.

As part of the ARCHER Knights Landing (KNL) processor testbed, we have produced and collected a set of benchmark reports on the performance of various scientific applications on the system. This has involved the ARCHER CSE team, EPCC's Intel Parallel Computing Center (IPCC) team, and various users of the system all benchmarking and documenting the performance they have experienced.

Wee Archie: a wee bit of history
Some time ago (actually 2015), EPCC built a Raspberry Pi cluster called Wee Archie to demonstrate some of the principles behind a full-sized supercomputer. We designed the cluster to be portable as we can't carry around a real supercomputer and just looking at a laptop "connected" to some remote system isn't that engaging.
