Dynamic Memory Managment in C++

Sperens, Martin January 2019 (has links)
Memory allocation is an important part of program optimization as well as of computer architecture. This thesis examines some of the concepts of memory allocation and tries to implement overrides for the standard new and delete functions in the c++ library using memory pools combined with other techniques. The overrides are tested against the standard new and delete as well as a custom memory pool with perfect size for the allocations. The study finds that the overrides are slightly faster on a single thread but not on multiple. The study also finds that the biggest gain on performance is to create custom memory pools specific to the programs needs. Lastly, the study also lists a number of ways that the library could be improved

Visualization of Dynamic Memory in C++ Applications / Visualisering av Dynamiskt Minne i C++ Applikationer

Salén, Filip January 2019 (has links)
Optimized memory management is important for a demanding application to achieve high-performance results. But un-optimized or unwanted memory behaviors can usually be difficult to detect without an overview of how memory is structured during run-time. This thesis explores real-time visualization of dynamic memory allocation for applications using the memory pool allocation technique. In the thesis, technical and graphical challenges are described together with their solutions and the design choices that were made. The final result is a program that can visualize dynamic memory management in real time, with the focus on displaying a detailed and comprehensive memory overview that preserves the level of detail over time. / Optimerad minneshantering är viktig för att uppnå hög prestanda i en krävande applikation. Men att upptäcka icke optimerade eller oönskade minnesbeteenden kan vara svårt utan en visuell översikt över hur minnet är strukturerat under programmets exekvering. Denna avhandling undersöker hur dynamisk minnesallokering kan visualiseras i realtid för applikationer som använder allokeringstekniken minnes\-pool. I avhandlingen beskrivs tekniska och grafiska utmaningar tillsammans med deras lösningar och de designval som gjordes. Slutresultatet är ett program som kan visualisera dynamisk minneshantering i realtid och som fokuserar på att visa en detaljerad och omfattande minnesöversikt som bevarar detaljeringsgraden över tiden.
