Student Poster Winners at CHPC 2015 Conference

The CHPC National Conference held from 30 November to 4 December 2015 featured 20 student researchers who demonstrated their work through posters. Thy came from various South African institutions of higher learning and across many research domain and showcased their CHPC facilitated research.  

A panel of five independent judges, experts in the fields of engineering, biomedical applications, computational chemistry and material science evaluated the posters, most of which were in one of these fields. Five evaluation criteria were used, namely: presentation, use of high performance computing (HPC), scientific merit, quality of work and insight. The judges initially evaluated each poster independently, then compared notes and made a group decision on the winners.



In third place there were four winners:

  1. Sesham Srinu (UCT) – HPC and Computer Science: Optimal Approximate Entropy Detection for Dynamic Spectrum Access in Cognitive Radio
  2. Jean-Paul Fouche (CUBIC) – Health and Life Sciences: The ENIGMA-HIV working group: Association of CD4 with subcortical volume in HIV-positive adults
  3. Mofuti Mehlape (UL) – Material Science: Computational Modelling Studies of Pentladite Minerals: Atomistic Simulators Study
  4. David Tshwane (UL) – Material Science: Generation of MnO2 Nanotubes using Computer Simulation Strategy
Second Place
Elumalai Pavadai (UCT) – Computational Chemistry: (IN ABSENTIA) New Human Malaria Parasite Dihydroortate Dehydrogenase Inhibitors by Pharmacophore and Structure-based Virtual Screening.
First Place
Arodola Olayide (UKZN) -- Health and Life Sciences: Flap Dynamics Study of Human Cathespin D in the Treatment of Breast Cancer using Multidimensional Computational Analysis

Parliamentary Portfolio Committee on S&T visits CHPC

The Parliamentary Portfolio Committee on Science and Technology (PPCST) visited the Centre for High Performance Computing (CHPC) in Rosebank, Cape Town on 12 August 2015 where they gained insights on the centre's operations, challenges and future plans.

CHPC Director, Dr Happy Sithole offered a presentation of the centre's structure, key operations and high level projects to the 10 committee members, who were especially interested in the centre's interactions with South African commercial industry; its involvement in the Square Kilometre Array project and the centre's network connectivity to South African universities, research councils and to the world at large.

The PPCST was accompanied by a high-level delegation from the Department of Science and Technology and the CSIR. The committee plans to visit other science, technology, engineering, mathematics (STEM) entities in the country in an effort to acquire a broad understanding of the South African STEM landscape.

CHPC takes 2nd prize in 2015 Student Cluster Competition

On 15 July the CHPC student team took second honours at the 4th High Performance Computing Advisory Council HPCAC-International Supercomputing Conference (ISC) Student Cluster Competition, , where more than 2,600 attendees and 160 exhibitors from around the globe met in Frankfurt, Germany.  


The competition featured small teams that competed to demonstrate the incredible capabilities of state-of- the-art high-performance cluster hardware and software. In a real-time challenge, 11 teams of six undergraduate and/or high school students built small clusters of their own design on the ISC exhibit floor and raced to demonstrate the greatest performance across a series of benchmarks and applications.


The students received a unique opportunity to learn, experience and demonstrate how high-performance computing influence our world and day-to-day learning. Held in collaboration with the HPCAC and ISC, the Student Cluster Competition is designed to introduce the next generation of students to the high performance computing world and community.


Final results were as follows:

1st place:Tsinghua University, China

2nd place:Centre for High Performance Computing (CHPC)

3rd place:University of Science and Technology of China

Highest LINPACK performance:Jamia Millia Islamia University, India

Fan favourite:Purdue University & Universidad EAFIT

China retains supercomputing crown in latest Top 500 ranking

A supercomputer developed by China's National Defense University remains the fastest publically known computer in the world, while the U.S. is close to an historic low in the latest edition of the closely followed Top 500 supercomputer ranking, which was published on 13 July 2015.

The Tianhe-2 computer, based at the National Super Computer Center in Guangzhou, has been on the top of the list for more than two years and its maximum achieved performance of 33,863 teraflops per second is almost double that of the U.S. Department of Energy's Cray Titan supercomputer, which is at the Oak Ridge National Laboratory in Tennessee. The IBM Sequoia computer at the Lawrence Livermore National Laboratory in California is the third fastest machine, and fourth on the list is the Fujitsu K computer at Japan's Advanced Institute for Computational Science. The only new machine to enter the top 10 is the Shaheen II computer of King Abdullah University of Science and Technology in Saudi Arabia, which is ranked seventh.

The Top 500 list, published twice a year to coincide with supercomputer conferences, is closely watched as an indicator of the status of development and investment in high-performance computing around the world. It also provides insights into what technologies are popular among organizations building these machines, but participation is voluntary. It's quite possible a number of secret supercomputers exist that are not counted in the list. With 231 machines in the Top 500 list, the U.S. remains the top country in terms of the number of supercomputers, but that's close to the all-time low of 226 hit in mid-2002. That was right about the time that China began appearing on the list. It rose to claim 76 machines this time last year, but the latest count has China at 37 computers. While there are few major changes in the top positions in the ranking, the aggregate computing power of the 500 systems continues to advance, but the pace is slowing.

The current list represents 361 petaflops per second of performance, up 31% compared this time last year, but is a noticeable slowdown in growth, according to the authors of the study. The rise of the use of graphics processors, so-called GPU computing, is reflected in the top 10. Two machines used Nvidia K20x processors: the second-ranked Cray Titan and sixth-ranked Cray Piz Daint, which is installed at the Swiss National Supercomputing Centre. But Intel's Xeon E5 chip continues to outrank all others. Taken together, three generations of the chip (SandyBridge, IvyBridge and Haswell) are in 80% of the systems, representing 67% of total performance. The Top 500 list is compiled by supercomputing experts at the University of Mannheim, Germany; the University of Tennessee, Knoxville; and the Department of Energy's Lawrence Berkeley National Laboratory.
