Re: GSoC libgomp task project: What should I do next?

Hello Tobias, I think it makes sense to start working on libgomp; even if the chosen implementation is not perfect, one can make real-world experiments with it. Additionally, to be used at the end, it has to end up in libgomp. Thank you for your advice. I'll work on libgomp soon. Sho

Re: GSoC libgomp task project: What should I do next?

Hi Jakub, Yeah. And, please post patches from time to time, even if they aren't completely finished, so that others can comment on them. OK. I'll work on it. Sho Nakatani

GSoC libgomp task project: What should I do next?

the emulation codes by: $ make test_fib_by_hand $ export OMP_NUM_THREADS=(int number) $ ./test_fib_by_hand (N for fib(N)) [3] http://nanos.ac.upc.edu/content/barcelona-openmp-task-suite Sho Nakatani libgomp_lock_fib.eps Description: PostScript document

Re: My current idea for improving libgomp

structures, most accesses to task queues should be rewrote, then most codes related to task scheduler should be rewrote, too. Give me any comment freely on this point since it is very important point in my project ;-) Thanks, -- Sho Nakatani

Re: My current idea for improving libgomp

to other ones like taskwait, barrier, and parallel. Thanks, -- Sho Nakatani

, C. Addison et al. - A Runtime Implementation of OpenMP Tasks, J. LaGrone et al. Thanks. I'll read all of them ;-) -- Sho Nakatani

Re: My current idea for improving libgomp

' using breadth-first scheduler, and after that I'll implement `untied task' using work-first scheduler (if I have time). Thanks, -- Sho Nakatani

My current idea for improving libgomp

Hi, I'm Sho Nakatani, accepted by Google Summer of Code 2011. I'm trying to add speed-up to libgomp, an OpenMP implementaion in GCC. As GSoC project, I'll focus on OpenMP `task' directive (especially `tied task'). Around the beginning of April, some members here told me that I can migrate

Re: Give me advice on GSoC OpenMP

tied and untied task, I'll continue to try them after GSoC term finish. Antoniu Thanks, -- Sho Nakatani

Give me advice on GSoC OpenMP

Hi! I'm Sho Nakatani, a student of the University of Tokyo, Japan. I'd like to tackle GSoC this year! I'm trying to speed up the OpenMP implementation in GCC. The following graph shows the OpenMP in GCC is much slower than that of Intel C Compiler. https://github.com/laysakura/GCC-OpenMP

Re: Give me advice on GSoC OpenMP

GOMP is slower compared to icc implementation but to make my idea clear for myself :-) So, I need to know OpenMPI API to get tasks info like: - A task is created - A task finished its job - On which CPU core a task is on Do you know any document? Thanks, -- Sho Nakatani
