At the EGEE User Forum in Uppsala, the author, Bruce Becker of the Meraka Institute and coordinator of the South African National Grid, called for making an AfricaGrid a reality. Here he outlines the reasons why now is the opportune time for work on this to be starting in earnest.
For some years now, many have been hinting at an “AfricaGrid.”
In the Mediterranean basin, we have seen many African countries participating directly in EUMedGrid (and more recently EUMedSupport).
In the southern region of Africa, we have seen much activity over the last couple of years that allows to envisage at least a “Sub-Saharan Grid.”
This prospect is very appealing to the r

Registration for the ninth DOSAR Workshop, which takes place 6-8 April 2010 in Pilanesburg, South Africa, is now open.
The Distributed Organization for Scientific and Academic Research (DOSAR) congregates institutions from the southern US, Latin America, and South Africa that are involved in the development of grid computing technology for major high energy physics experiments.
The DOSAR Workshop series is designed as an instrument to improve the relationship among all groups and exchange information about the latest developments in the various analysis centers.
This workshop will be held at the Kwa Maritane Game Lodge, which is in Pilanesburg, two hours drive from Johannesburg, South Africa. The local organizing committee is the University of Johannesburg.
The workshop will cover:

The School for Grid Application Porting is now accepting applications from students with experience in shell programming.
The event, which is sponsored by the South African National Grid, EGEE II, and GILDA, will take place 15-26 March 2010 in Johannesburg. It will be hosted by University of Johannesburg and University of Witwatersrand.
In scientific research, collaboration, resource sharing, advanced computing facilities and data are enabling the acceleration of discovery, innovation, and efficiency more than ever. The grid computing paradigm is a crucial aspect of today's e-Science, and national infrastructures have been deployed worldwide, with a strong emphasis on usability, interoperability and collaboration. However, development and support of the user communities is just as crucial as tha

Image of the week - Monumental modeling

Despite the monumental nature of the world’s heritage sites, they are quite vulnerable to the vicissitudes of their environment. Wind and water erosion wear them down, destroying historic features we may never be able to recapture.
To understand how the winds are changing the shape of the monuments on the Giza Plateau in Egypt, Ashraf Hussein and Hisham El-Shishiny created a three dimensional model of the region. Then they simulated the flow of the wind across the Giza Plateau to see where the wind pressure and friction is greatest.
This simulation was unusual because it had to handle large differences in scale among the various monuments on the Giza Plateau. To complicate matters, within the lower atmosphere the wind field must be resolved on very fine scales to achieve a high level of accuracy, said El-Shishiny.
To complicate matters, the problem size was much greater than the available computational resources. Ultimately, they ran the simulations on a c

Feature: MANGO-NET - Helping to bring African ICT up to speed

While computing technology is ubiquitous and increasingly powerful, its availability in developing nations remains limited. African universities struggle to participate in cutting-edge research because they do not have access to a widespread computer infrastructure, so their ability to conduct experiments and share results is compromised. As more science becomes “e-science,” the problem gets worse.
To help solve this, MANGO-NET (Made in Africa NGO NETwork), was launched. This project seeks to boost information and computing technology (ICT) throughout Africa, by establishing a network of schools and production labs to train ICT students to build their own computers. Because components are bought in bulk, it should reduce hardware costs, decreasing African depe

Feature - BOINC gets social with Facebook

A screen shot of Progress Thru Processors.

For the first time, Facebook users are signing on to volunteer grid computing, thanks to a new application called Progress thru Processors.
“For all the promise of volunteer computing, the problem is that no one’s ever heard of it,” said Matt Blumberg, executive director of Grid Republic, “and that’s a big deal for a technology where the utility of the thing is a function of the number of people who participate.”
Progress thru Processors could change all that. The project was developed jointly by Intel, Grid Republic, and the Berkeley Open Infrastructure for Network Computing. BOINC, which was originally created at University of California at Berkeley to assist in analyzing data in the search for extraterrestrial intelligence (SETI), is the platform on which Grid Republic’s software is based. Progress thru Processors is an adaptation of Grid Republic’s so

Feature - Blue Gene for Africa Image courtesy of the Meraka Institute IBM donated a supercomputer to South Africa's Center for High-Performance Computing, as part of a $120 million investment in sub-Saharan Africa. Dubbed "Blue Gene" and designed and built in collaboration with the Department of Energy's NNSA/Lawrence Livermore National Laboratory in California, it is capable of 11.5 teraflops, or 11.5 trillion floating point operations per second, or flops. ("Flops" are a standard measure of a computer's performance.) In other words, it is currently the fastest scientific computer on the entire African continent.The computer system is part of a larger initiative, known as "Blue Gene for Africa" (BG4A), that aims to build high-end computing capacity in the continent. The project aims to develop infrastructure, encourate collaborative science,  and promote Africa's human capital. As such, it will be available free of charge to any qualifying African institution for use on advanced

Feature - Rough waters: fighting modern-day pirates with technology

In the past year, maritime shipping has suffered a resurgence of piracy, at a level that the world has not seen since the early 18th century. Sailors working off the Horn of Africa have been particularly hard hit: last year, records show that 125 ships were attacked and 45 seized.
Real numbers are likely much higher, as piracy is believed to be widely under-reported. One of the world's busiest shipping lanes, about 20,000 ships annually pass through the Gulf of Aden on their way to and from the Suez Canal — carrying a tenth of world trade.
Unlike the popular image of pirates seen in movies and books, modern pirates are more likely to wield machine guns than muskets; and the crime remains as difficult to fight as it ever

Today, the average personal computer can do a few GigaFLOPS (the acronym refers to doing one billion FLoating-point Operations Per Second). A modest cluster might do one thousand GigaFLOPS, or 1 TeraFLOPS. And for several years, one thousand TeraFLOPS, or one PetaFLOPS, was the Holy Grail
