CHPC students read more — The top finishing UFS team, Team 5, consisting of Nhlonipho Shezi, Kgoboketso Mphahlele, Albert van Eck (mentor), Itumeleng Khaka, and Bophelo Pharasi came third during the national round of the National Integrated Cyber Infrastructure Systems (NICIS) CHPC’s Student Cluster Competition.

Two students from the University of the Free State (UFS) who took part in the National Integrated Cyber Infrastructure Systems (NICIS) CHPC Student Cluster Competition were selected as part of the National Team to compete at the International Supercomputing Conference (ISC) Student Cluster Competition next year.

Itumeleng Khaka and Nhlonipho Shezi, both currently studying towards a Bachelor of Science degree in Information Technology majoring in Computer Science and Business Management, were part of one of the university’s teams (Team 5) that took third place during the national round of the competition.

Bophelo Pharasi (Bachelor of Science in Information Technology majoring in Computer Science and Business Management) and Kgoboketso Mphahlele (Bachelor of Computer Information Systems) were the other team members, and Albert van Eck, Head of the eResearch and High-Performance Computing Unit, was their mentor. The UFS entered three teams for the competition.

Another student, Limpho Senatla (Bachelor of Science in Information Technology), was awarded the prize for the female student with the most potential during this competition. Some of the prizes awarded to her include an opportunity to work under the mentorship of sponsors such as Tsolo.io, Diplomics, Intel, and the South African Radio Astronomy Observatory (SARAO).

The other two teams that also participated were Team OptiCompute (mentor: Hendrik van Heerden), consisting of Senatla, Siphesihle Mvelase (Bachelor of Science in Information Technology majoring in Computer Science and Business Management), Ziphezinhle Malinga (Bachelor of Science in Information Technology majoring in Computer Science and Business Management), Ennosse Mkhutyukelwa (Bachelor of Science in Information Technology majoring in Computer Science and Chemistry); and Team KKRT (mentor: Zirke le Roux), consisting of Kananelo Nyakallo Mofokeng (Bachelor of Science in Information Technology majoring in Computer Science and Physics), Boitumelo Ramasike (Bachelor of Science in Information Technology majoring in Computer Science and Business Management), Kamohelo Kolanchu (Bachelor of Science in Information Technology majoring in Computer Science and Mathematics), and Thabang Maokeng (Bachelor of Computer Information Systems).

Highly stressful and demanding

“Since 2017, the UFS has competed in the CHPC Student Cluster Competition, with various successful outcomes. This year was no exception, with Team 5 winning third place at the national round. All teams endured a highly stressful and demanding round where external factors such as load shedding, late and incomplete hardware deliveries, extreme heat, and sleep deprivation played a role,” says Van Eck.

According to its website, the Centre for High-Performance Computing (CHPC), a division of the Council for Scientific and Industrial Research (CSIR), annually hosts a Human Capital Development (HCD) programme for undergraduate students currently enrolled in Science, Technology, Engineering and Mathematics (STEM) fields at South African universities. They undergo training that will take them from zero knowledge of HPC to being able to build mini clusters through various rounds.

The competition is held annually and consists of three rounds: a selection, national, and international round. A team composed of four undergraduate (second-year) students can enter the competition.

This year, twenty teams from eight universities participated in the selection round. Each year, this round is hosted at a different university in the country, with the UFS Bloemfontein Campus playing host this year from 10 to 15 July. During the first round, students were exposed to various technologies and concepts used in HPC and scientific computing. Students were then evaluated according to their technical skills acquired during the selection round, and had to design, present, and defend a cluster design with its network topology.

The national round, for which all three UFS teams qualified, was held at the Kruger National Park from 3 to 8 December.

Travel internationally

According to Van Eck, the students were given a limited budget to procure a small cluster for this round. Students then had to assemble the cluster and start configuring it during this round. After installing and configuring their clusters, students had to install and optimise scientific software. Installing and optimising scientific software is quite challenging. One must consider various technologies such as hardware components, networking, operating systems, compilers, intercommunication between processes, and the functionality of the software.

The winning team in the national round is combined with two members of either the second or third-place winners and two reserves selected from those teams. This team will travel to Austin, Texas, early next year to visit the Texas Advanced Computing Centre (TACC). Students will also undergo more training at Dell Labs in the USA.

The team will compete at the International Supercomputing Conference (ISC) Student Cluster Competition (SCC) against teams from across America, Europe, and Asia. This competition is held in Germany and sees the best international students competing in the final round. The South African teams have won this round on several occasions.

“The competition takes all students out of their comfort zones. The technologies and methodologies they are exposed to are state-of-the-art in theoretical and computational sciences. In the first round, students are trained by industry professionals on concepts they would otherwise never be exposed to. They come into contact with multiple disciplines within IT, engineering, and some scientific fields. The learning curve during this competition is immense, but students who rise to the challenge reap the benefits in the long run. With prizes such as laptops, prize money, and mentorship from the industry, multiple opportunities can be utilised,” says Van Eck.

Exposure to various technologies

Van Eck says even members from teams that do not make it into the top positions can benefit from exposure to various technologies and networking with other delegates. Leveraging knowledge attained during the competition also enhances one's ability to apply knowledge to other parts of one's career.

“To become an HPC specialist, one must master various field-specific domains, and each of these domains can become a career in itself should a student identify a specific field of more interest to them. This type of exposure is usually only experienced once one enters the workforce. It may be difficult and costly to enter a specific domain by that time. Earlier exposure during a competition like this can assist a student in identifying which fields of science, engineering, or IT they would like to focus on and perhaps later specialise in.”

Bloemfontein's quality of tap water compares very favourably with bottled water

2009-08-04

The quality of the drinking water of five suburbs in Bloemfontein is at least as good as or better than bottled water. This is the result of a standard and chemical bacterial analysis done by the University of the Free State’s (UFS) Centre for Environmental Management in collaboration with the Institute for Groundwater Studies (IGS).

Five samples were taken from tap water sources in the suburbs of Universitas, Brandwag, Bain’s Vlei, Langenhoven Park and Bayswater and 15 samples were taken of different brands of still and unflavoured bottled water. The samples were analysed at the laboratory of the IGS, while the interpretation of the analysis was done by the Centre for Environmental Management.

“We wanted to evaluate the difference in quality for human consumption between tap water and that of the different brands of bottled water,” said Prof. Maitland Seaman, Head of the Centre for Environmental Management.

“With the exception of two samples produced by multinational companies at their plants in South Africa, the different brands of bottled water used for the study were produced by South African companies, including a local small-scale Bloemfontein producer,” said Prof. Seaman.

According to the labels, the sources of the water vary from pure spring water, to partial reverse osmosis (as an aid to standardise salt, i.e. mineral, content), to only reverse osmosis (to remove salts). (Reverse osmosis is a process in which water is forced under pressure through a pipe with minute pores through which water passes but no – or very low concentrations of – salts pass.)

According to Prof. Seaman, the analysis revealed some interesting findings, such as:

• It is generally accepted that drinking water should have an acceptable level of salt content, as the body needs salts. Most mineral contents were relatively higher in the tap water samples than the bottled water samples and were very much within the acceptable range of drinkable water quality. One of the bottled samples, however, had a very low mineral content, as the water was produced by reverse osmosis, as stated on the bottle. While reverse osmosis is used by various producers, most producers use it as an aid, not as a single method to remove nearly all the salts. Drinking only such water over a prolonged period may probably have a negative effect on the human physiology.

• The pH values of the tap water samples (8,12–8,40) were found to be slightly higher (slightly alkaline), like in all south-eastern Free State rivers (from where the water is sourced) than the pH of most of the bottled water samples, most of which are sourced and/or treated in other areas. Two brands of bottled water were found to have relatively low pH levels (both 4,5, i.e. acidic) as indicated on their bottles and as confirmed by the IGS analysis. The health implication of this range of pH is not significant.

• The analysis showed differences in the mineral content given on the labels of most of the water bottles compared to that found by IGS analysis. The possibility of seasonal fluctuation in content, depending on various factors, is expected and most of the bottling companies also indicate this on their labels. What was a rather interesting finding was that two pairs of bottled water brands claimed exactly the same mineral content but appeared under different brand names and were also priced differently. In each case, one of the pair was a well-known house brand, and the other obviously the original producer. In one of these paired cases, the house brand stated that the water was spring water, while the other (identical) “original” brand stated that it was spring water treated by reverse osmosis and oxygen-enriched.

• Nitrate (NO3) levels were uniformly low except in one bottled sample, suggesting a low (non-threatening) level of organic pollution in the source water. Otherwise, none of the water showed any sign of pollution.

• The bacterial analysis confirmed the absence of any traces of coliforms or E.coli in any of the samples, as was also indicated by the bottling companies. This is very reassuring. What is not known is how all these waters were sterilised, which could be anything from irradiation to chlorine or ozone treatment.

• The price of the different brands of bottled water, each containing 500 ml of still water, ranged between R3,99 and R8,99, with R5,03 being the average price. A comparison between the least expensive and the most expensive bottles of water indicated no significant difference in quality. In fact, discrepancies were observed in the most expensive bottle in that the amount of Calcium (Ca) claimed to be present in it was found to be significantly different from what the analysis indicated (29,6 mg/l versus 0,92 mg/l). The alkalinity (CaCO3 mg/l) indicated on the bottle was also found to differ considerably (83 mg/l versus 9,4 mg/l). The concentration of Total Dissolved Salts (TDS) was not given on the product.

“The preference for bottled water as compared to Bloemfontein’s tap water from a qualitative perspective as well as the price discrepancy is unjustifiable. The environmental footprint of bottled water is also large. Sourcing, treating, bottling, packaging and transporting, to mention but a few of the steps involved in the processing of bottled water, entail a huge carbon footprint, as well as a large water footprint, because it also requires water for treating and rinsing to process bottled water,” said Prof. Seaman.
