Hi All,
I applied gsoc for openMP taks scheduling and my advice may cover
taskyield facility. Currently i have some idea for taskyield. i think
i can add something. Therefore i wonder GCC mentor related about

Dear All,
Thank you for your reply Tobias.
By the way Mr Jakup I hope my approach is make sense for you.
I changed GOMP_SPINCOUNT factor and i got speedup more than.
I attached my trace that was profiled extrae and paraver. Light blue
mean idle, Dark blue mean running, Yellow scheduling, Fork/Jo

Regarding busy waits, you could try to tune the values of the
GOMP_SPINCOUNT environment variable. Search for "@node GOMP_SPINCOUNT"

Dear All,
I'm trying to speed up the OpenMP implementation in GCC and Intel
compiler. I'm working on multisort because i thought it has too much
branches and i applied tree model task. I used Paraver and Extrae to
profile program After that, I executed them on a machine Minotauro
supercomputer in
Hi,
I'm MSc High-Performance Computing student at Polytechnic University
of Catalonia(BarcelonaTech). I'm interesting openmp task scheduling
optimization or openmp 3.1 facility taskyield.
@For Task scheduling
I'm using mercurium compiler already at my university because the
compiler was developed
