Parallel Application Development with Intel Threading Tools
Vadkerti, Ladislav ; Jaroš, Jiří (referee) ; Dvořák, Václav (advisor)
Today's trend in microprocessor design is increasing the number of execution cores within one single chip. Increasing the processor's clock speed reached its limit with growing power consumption. This trend brings new opportunities to software developers, as they can take advantage of real multithreading in their applications. But a lot of new problems to solve appear with threading compared to sequential programming. With proper design, threading can enhance performance by making better use of hardware resources. However, the improper use of threading can lead to performance degradation, unpredictible behavior, or error conditions that are difficult to solve. For this reason Intel developed a suite of tools, that can help software developers to analyze performance and detect coding errors in thread interactions. This thesis focuses on the examination of ways that this tools can be used in multithreaded application development.

Using GPU for HPC
Máček, Branislav ; Szőke, Igor (referee) ; Kašpárek, Tomáš (advisor)
Recently there was a significant grow in building HPC systems. Nowadays they are building from mainstream computer components. One of them is graphics accelerators with GPU. This thesis deals with description of graphics accelerators. It examines possibilities usage. GPU chip has hundreds simple processors. This thesis examine possibilities how to benefit from these parallel processors. It contains description of several testing applications, discuss results from experiments and compares them with another components used for HPC.
