“Hey, thought this might be of interest…” A one line email with a link from my supervisor this spring. The website was of course, summerofhpc.prace-ri.eu, and I did in fact, find it of interest. The opportunity to work in a European research institute, learning more about how we can use powerful computers to model the world around us? I could not wait for the application period to start!
Therefore, when in April I was invited by PRACE to work on graphene modeling at the Jülich Supercomputing Center (JSC) in Germany over the summer, I was extremely excited! As a University of Manchester student, I already had the chance to hear about graphene from the very best working in the field of nanomaterials – including Nobel laureate Sir Andre Geim himself. Now I would have the chance to explore how its electronic properties are modeled. On the other hand, I suddenly grew nervous. What if all the other participants were computer geniuses, talking jibberish Linux jargon, while I only have a bit of experience with C++ programming?
Well, on this 1st of July 2018 Sunday, after arriving in the beautiful Edinburgh, I finally met the other PRACE Summer of HPC students. Everyone turned out to be very friendly and actually, there were plenty of other non-computer scientists in our group – physicists, mathematicians, engineers… The first night was reserved for getting to know each others in the traditional British way, i.e. in the pub. Sure, we talked a bit about our projects, but mostly it was like any other night out with a group of students, talking about our home countries and universities, struggling to choose from the long list of burgers…
The first day of training seemed to go well for everyone. We learned about Edinburgh’s ARCHER supercomputer, a group of 4920 computers which can co-operate to solve large problems. Although I’d never even logged on to a computer using remote access, with the training team’s clear instructions and hands-on exercises, I was soon running my first program on ARCHER. I learned a lot, and after a long day involving lots of new terminology (did you know a program can be “embarrassingly parallel”?) and screen-time, I even had time for a jog around Arthur’s seat, the prominent and beautiful hill just next to our accommodation.
Our second training day was cut short, as we left for a bus tour around the town. Despite the traffic, we had the chance to see Edinburgh castle, and maybe even a glimpse of some royal visitors in the distance (or at least a very large hat). We finished off the day at Illegal Jack’s Mexican restaurant. I have to say, vegetarian haggis actually makes for a great burrito topping!
We still have a couple of days left in Edinburgh, and then each of us will fly off to get started on our research projects. It’s great to know that we will be keeping in touch with each other though, both to hear about everyone’s interesting projects, and of course to maintain and strengthen the friendships already forming. I for one am very much looking forward to this Summer of HPC!
