Effective visualisation of callgraphs for optimisation of parallel programs: a design study by Mabakane, Mabule Samuel

“…Visualisation tools are used to identify performance bottlenecks of parallel applications in an attempt to optimize the execution of the programs and fully utilise the available computational resources. TAU (Tuning and Analysis Utilities) callgraph visualisation is one such tool commonly used to analyse the performance of parallel programs. …”

Relay assisted device-to-device communication with channel uncertainty by Uyoata, Uyoata Etuk

“…The formulated rate maximization problem is solved for deterministic and probabilistic constraint scenarios, and the problem extended to a multiple-input single-out scenario for which robust beamforming was designed. Finally, relay utility and social distance based selection algorithms are proposed for full duplex decode and forward device-to-device communication set up. …”
