 \n\nCompiler and Runtime Based Parallelization and Optimization for GPUs\n
 \nOzen, Labarta, Ayguade\n\nThis thesis targets directive-based programmin
 g models to enhance their capability for GPU programming.  It introdu
 ces a new dialect model, which is a combination of OpenMP and OmpSs. The n
 ew model allows the use of multiple GPUs in conjunction with the heavily m
 ultithreaded capabilities in multicore processors automatically. The thesi
 s also focuses on code transformation techniques and proposes the LazyNP m
 ethod to support nested parallelism for irregular applications such as spa
 rse matrix operations, graph and graphics algorithms. Finally, the thesis 
 conducts a thorough exploration of loop scheduling methods on GPUs to find
  the advantage and disadvantages of them. It then proposes the concept of 
 optimized dynamic loop scheduling.<br /><br />The contributions of this th
 esis improve the programmability of GPUs. This has had an outstanding impa
 ct on the whole OpenMP and OpenACC language committee. Additionally, it in
 cludes contributions to widely used compilers such as Mercurium, Clang and
  PGI compilers.
