HPC Europa3: My visit

Author: Guest blogger
Posted: 7 Aug 2018 | 10:28

Dr Martin Lepšík came on an HPC-Europa3 visit from 16-29 July and was hosted by Dr Emanuele Paci at the University of Leeds. Martin started his visit by coming to Edinburgh.

My name is Martin Lepšík, and I am a Czech computational structural biologist. After 11 years of fruitful research in quantum mechanics-based drug design (at P. Hobza’s group at IOCB, Prague, CR), I decided to enrich my expertise with enhanced-sampling molecular dynamics of lectin-carbohydrate complexes, important for human health and disease.

PRACE Summer of HPC brings the summer to Edinburgh

The PRACE Summer of HPC 2018 provides an opportunity for up to 23 applicants from across Europe to apply to one of the PRACE supercomputing centres to work on a PRACE-related piece of work for eight weeks over the summer. 

The projects are preceded by a training week, hosted this year by EPCC in Edinburgh alongside ARCHER and PRACE Advanced Training Centre courses. The training week is designed to build a community between the Summer of HPC participants and to provide the necessary skills for students to begin their projects. Flights and accommodation are provided by the programme with a stipend to cover living costs.

HPE Apollo System

The closing date for our Highly Skilled Workforce scholarships, open to Scottish and EU students, has been extended to May 28th. Scholarship applications should be made after completion of an MSc application. See https://www.ed.ac.uk/studying/postgraduate/applying/.

We also have a scholarship for the MSc in HPC with Data Science programme that is provided by the Registers of Scotland. The closing date is May 21st - see https://www.ed.ac.uk/student-funding/postgraduate/uk-eu/science-engineering/informatics/registers-of-scotland

Both the above have nationality restrictions - our own John Fisher scholarships are open to all. See https://www.ed.ac.uk/student-funding/postgraduate/uk-eu/science-engineering/informatics/masters-hpc

You can see details of both HPC Masters courses at the Computing and Informatics web page.

The show must go on: extreme weather at the ACF

On Wednesday 28th February, Edinburgh and the Central Belt of Scotland saw an unprecedented volume of snow fall in a short space of time. Around late morning that day, the Scottish Transport Minister Humza Yousaf unexpectedly upgraded the extreme weather warning from Amber to Red from 15:00 on 28th February, suggesting widespread damage, travel and power disruption, and a risk to life were likely.

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).

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.

X windows and XQuartz on ARCHER

Paraview and ARCHERX Server

Every so often we get an ARCHER query where Paraview isn't working for somebody. As Paraview requires remote window functionality (X Servers) and can also do offscreen rendering and all sorts of other things, it can be complicated to get it working properly and efficiently. 

ARCHER code developers and presenting performance

Application performance

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. 

Secure access to remote systems

06/09/16: As pointed out by my colleague Stephen in the comments after this post, the way to solve most of these issues is to tunnel the key authentication and therefore bypass the need to have private keys anywhere but on my local machine.  I'm always learning :)

Password vs key

Having to remember a range of passwords for systems that I don't use regularly is hard. 

You can use a password manager, but that only helps if I'm only ever trying to log in from my own laptop. If I have to log in from someone else's machine for any reason then I'd need to know the password.
