OpenBSD on PDA
Vašut, Marek ; Galamboš, Leo (advisor) ; Děcký, Martin (referee)
In the present work we study a process of porting the OpenBSD operating system kernel to a Palm Tungsten T|5 handheld device. The begining of this work explains main characteristics of the ARM architecture as well as the principle of internal workage of the OpenBSD kernel. The further part is then about porting the kernel, starting with bootloader development, necessary modifications of the kernel, explaining a process of developing custom drivers and installing the system. This work also explains possible common problems that may arise alongside the process. At the end is also explained a basic post-installation system setup and directions to rebuild the system from source codes on the PDA.
Green Clusters
Vašut, Marek ; Galamboš, Leo (advisor) ; Kruliš, Martin (referee)
The thesis evaluates the viability of reducing power consumption of a contem- porary computer cluster by using more power-efficient hardware components. The cluster in question runs an Map-Reduce algorithm implementation and the worker nodes consist of either systems with an ARM CPU or systems which combine both an ARM CPU and an FPGA in a single package. The behavior of such cluster is discussed from both performance side as well as power consumption side. The text discusses the problems and peculiarities with the integration of an ARM-based and especially the combined ARM-FPGA-based systems into the Map-Reduce framework. The Map-Reduce framework performance itself is eval- uated to identify the gravest performance bottlenecks when using the framework in the environment with ARM systems. 1
