Tertiary institution students visit CHPC to explore Africa's fastest supercomputer

Since the installation of the Centre for High Performance Computing’s fastest supercomputer – the Lengau cluster – in June 2016, the centre has been inundated with student visits from various tertiary institutions.

During the month of September the centre has had visits from the University of Limpopo and Walter Sisulu University. The visits formed part of faculties’ intentions to expose their students to various opportunities in industry and research institutions

 

.

 

The tours normally include presentations about the centre’s technical and research activities and visits to the different labs including the super computer room. “The students are always excited about the demonstration of the "mini-super computer" in the Advance Computer Engineering Laboratory (ACE-Lab),” said Dr Daniel Moeketsi, Senior Research Scientist at CHPC.

CHPC hosts Cluster Comparison Cape Town (CompaCT) 2016 Workshop

 
During 11-15 July 2016, 20 astronomers from around the world gathered under one roof at the CHPC in Cape Town to continue their efforts in trying to understand the scatter between different state-of-the-art hydrodynamical codes when simulating the growth and evolution of galaxy clusters. The CompaCT workshop, organised by Daniel Cunnama (UWC postdoctoral fellow) and Sean February (CHPC research scientist), attracted a number of local students and postdocs in the field. 
 
The workshop - the 3rd of its kind in a series of internationally hosted galaxy cluster comparison workshops that began in Madrid in 2014 - was a great success. Productivity levels were on par with previous workshops. Each participant was provided with access to one of CHPC's Ranger nodes (i.e. 16 cores, 64 GB RAM), which was managed by ACE lab's Israel Tshililo.

In keeping with previous workshops, the program for the week was dominated by sessions of working on projects of interest, engaging with collaborators, and presenting some interesting findings to everyone as they came up.

After a variety of comparisons for one particular galaxy cluster, this project already resulted in 5 publications with a few more expected to come out of the current workshop.

Comparison data is currently being made available for a additional 5 simulated galaxy clusters and various projects have been initiated during the week, including:
- Tracking individual halos through cosmic time to investigate pre-processing, gas stripping and backsplash.
- The formation and evolution of protoclusters.
- Ionization fractions at high redshift.
- Investigation into sources of hydrostatic mass bias.
 
The support of this workshop both technically and financially, demonstrated not only CHPC's, but more generally the Department of Science and Technology's, commitment to train and prepare young and local researchers for big data problems in Science and beyond.

CHPC wins 2016 Student Cluster Challenge

Frankfurt-Germany – CHPC has taken the top prize in the international Student Cluster Competition held at the International Supercomputing Conference (ISC) in Germany this week.

The CHPC is no new comer in this competition, having won the top prize in 2013 and 2014 and taken second prize in 2015, the centre entered yet another team of undergraduate students this year and took the overall prize, beating 11 other student contenders from across the globe.

Other entrants included:

·         Purdue University & University of Colorado, Boulder (USA)

·         Nanyang Technological University (Singapore)

·         National Energy Research Scientific Computing Center (USA)

·         University of Science and Technology of China (China)

·         University of Hamburg (Germany)

·         Tsinghua University (China)

·         University of Tartu (Estonia / USA)

·         Boston Green Team (USA)

·         Universitat Politècnica de Catalunya BarcelonaTech (Spain)

·         Huazhong University of Science & Technology (China)

·         Shanghai Jiao Tong University (China)

The awards ceremony took place on 22 June 2016 in front of ISC attendees from around the globe who met in Frankfurt to share the latest developments in HPC and to witness students expertise in what is hoped to become the formation of a pipeline for future HPC experts. The international competition features small teams that compete to demonstrate the incredible capabilities of state-of- the-art high-performance cluster hardware and software. In a real-time challenge, 12 teams of six undergraduates and high school students build a small cluster of their own design on the ISC exhibition floor and race to demonstrate the greatest performance across a series of benchmarks and applications.

Winning team members under the supervision of CHPC engineers, David Macleod and Matthew Cawood are:

·         Andries Bingani – University of the Witwatersrand

·         Ashley Naudé – Stellenbosch University

·         Avraham Bank – University of the Witwatersrand

·         Craig Bester – University of the Witwatersrand

·         Sabeehah Ismail – University of the Witwatersrand

·         Leanne Johnson – Stellenbosch University

Reserves:

·         Kayla-Jade Butkow – University of the Witwatersrand

·         Bakhekile Ndlovu – University of the Witwatersrand

 

The South African team is the only team that enters a brand new team each year. This is done to give as many students as possible exposure to the international HPC community. The international competition is a culmination of two rounds of national competition processes that CHPC starts every April with a call to students in all universities in the country.

The CHPC’s ISC Team was sponsored by Dell South Africa which provides the team with equipment, travel, accommodation, meals and training for the ISC competition. Mellanox sponsored the team’s EDR Infiniband interconnect (a high performance computer network technology operating at 100Gbps).

Team selection

The competition begins with team selection, a process designed to impart critical knowledge for building a cluster, this includes: using Linux systems, the basic software stack of a cluster and considerations which should be taken into account when choosing hardware. Team selection concludes with each team presenting a theoretical design for a student cluster to a panel of judges. The results from the team selection project and applications are used to select the teams which will proceed to the CHPC Student Cluster Competition, a national competition.

CHPC Student Cluster Competition (a national selection round)

In the CHPC Student Cluster Competition participants build small HPC clusters out of hardware provided by the CHPC and its industrial partners. The contest takes place on the exhibition floor at the CHPC national meeting annually. The participants are given a selection of applications to optimise and run on their cluster to demonstrate their design’s performance. Each team is assigned a budget of approximately R200000 and a parts list from one of the CHPC's industry partners. With this budget and parts list, the team must design a cluster taking into consideration the set of applications which will be used to benchmark the cluster. Once the cluster's design is finalised the hardware specification is submitted to the CHPC's partners for manufacturing. The hardware, as specified in the cluster design, is delivered to the exhibition floor of the CHPC national meeting. Here the teams unpack their equipment, construct their cluster, install the software stack and perform benchmarks. The teams are judged on a combination of the performance of the applications and the design of the cluster.
