(GSoC 2019) CPU-GPU Response Time and Mapping Analysis¶
Motivation¶
Through one of the subjects in my Master’s course, I carried on a project analyzing metrics of Software Models and visualizing it in APP4MC.
It was quite challenging as I was not very familiar with the Amalthea model and its APP4MC platform at first. But soon I was able to understand the concepts and started enjoying it. The project resulted in completing an application delivering performance and reliability metrics of a given Software Model. This is basically my motivation for participating in this Eclipse GSoC project, “CPU-GPU Response Time and Mapping Analysis”.
Since the topic’s ultimate goal is to achieve systems’ real-time determinism for modern HPC (High Performance Computing) applications, analyzing response times is essential and my basic knowledge in regard to, e.g., timing constraints or end-to-end event chain latency values according to the different communication paradigms (direct, implicit, LET: Logical Execution Time) which I obtained through my Master’s study were very helpful for me in order apply for and luckily realize this project.
Now that the industry’s interest has moved on to “Heterogeneous Systems”, I do hope that my GSoC work would be helpful for other researchers in this regard and make a contribution to the further development of the platform.
