Hi,
when i run benchmark_nop on Cell BE (PS3), i can see the speedup pretty
well.
When i take qa_fft.py as testcase i can't see the speedup.
All SPEs run the same code for same time. So when i use 6 SPEs, computing
takes the same time
as 1 SPE but it computes six times more.
I think i have to set gang_schedule() to true in gc_job_manager.h.
But how can i use this option in qa_fft.py?
def setUp(self):
ph =
gcell.program_handle_from_filename("../../gcell/lib/spu/gcell_all")
opts = gcell.jm_options(ph, 1)
self.mgr = gcell.job_manager(opts)
gcell.set_singleton(self.mgr)
gcell.jm_options() has only two parameters, in gc_job_manager.h there are 7
options.
Maybe, somebody can help me! I want to achieve, to see the speedup as well
with qa_fft.py as testcase.
Best Regards
Matty
