Xolisa Jevu graduated with honors from the University of Fort Hare in South Africa with a baccalaureate degree in Computer Science (CS). He’s currently registered in the master’s program and works as a junior lecturer in the CS department where he teaches object-oriented programming with Visual Basic.

As a computing laboratory assistant, Xolisa helps researchers and students use campus technology, and assists with hardware replacement, software installations and network troubleshooting. With a growing GIS program at the university, Xolisa is interested in learning more about industry best practices for data storage, stewardship and cybersecurity.

Since most universities in the Eastern Cape Province are in rural regions they lack faculty or staff who are experienced with HPC.  Xolisa intends to bridge that knowledge gap …

Brian Maistry is a systems administrator at the University of the Witwatersrand in South Africa where he supports the Ranger system, among others. He is responsible for the hardware and software used by the university’s statistics, actuarial, finance and computer science programs, including their contributions to the Square Kilometer Array project. He is familiar with a variety of operating systems, including Centos, Ubuntu, and Windows Server 2008. Additionally, he installs (and provides user support for) math and statistical software, including Matlab, Mathematica and R.

I’m looking forward to the TACC workshop, and SC15 where I can learn about the wide variety of cloud-enabled, and other methods in use around the world to support data-intensive research.  The experience will allow me to …

Nosiku Sikanyika is a systems administrator for ZAMREN, the Zambian Research and Education Network in southern Africa.

Among her Zamren duties are maintaining the high performance computing systems and configuring all network hardware. Additionally, she supports Windows and Linux servers, and manages authentication, Eduroam, and web hosting services.

In Austin, Nosiku hopes to sharpen her HPC skills, and increase her professional network.  She looks forward to meeting many more sys admins at the Special Interest Group for HPC in Resource Constrained Environments Birds-of-a-Feather session (SIGHPC-RCE).

Since we’re building a shared cyberinfrastructure in the sub-Saharan SADC region, I hope fewer of us will be “resource constrained” in the future. I’m excited about the research and education initiatives we will …
