SUMMARY:Compiler and Runtime Based Parallelization and Optimization for GP
Us
DESCRIPTION:Guray Ozen, Jesus Labarta, and Eduard Ayguade (Barcelona Super
computing Center, Polytechnic University of Catalonia)\n\nThis thesis targ
ets directive-based programming models to enhance their capability for GPU
programming. It introduces a new dialect model, which is a combination o
f OpenMP and OmpSs. The new model allows the use of multiple GPUs in conju
nction with the heavily multithreaded capabilities in multicore processors
automatically. The thesis also focuses on code transformation techniques
and proposes the LazyNP method to support nested parallelism for irregular
applications such as sparse matrix operations, graph and graphics algorit
hms. Finally, the thesis conducts a thorough exploration of loop schedulin
g methods on GPUs to find the advantage and disadvantages of them. It then
proposes the concept of optimized dynamic loop scheduling.
The
contributions of this thesis improve the programmability of GPUs. This ha
s had an outstanding impact on the whole OpenMP and OpenACC language commi
ttee. Additionally, it includes contributions to widely used compilers suc
h as Mercurium, Clang and PGI compilers.\n\nRegistration Category: Worksho
