Hello,
I'm trying to use PyCUDA for numerical calculations and I have some problems
with resourses. I want to integrate some function using Sympson method(scalar
multiplication of vector of Sympson coefficients and vector of function).
When I use simple function everything seems to be ok, but for some reason more
copmlex function rises an error: "pycuda._driver.LaunchError: cuLaunchGrid
failed: launch out of resources"
Traceback (most recent call last):
File "scalar_prod_complex_1_test.py", line 198, in <module>
func(dest,a_gpu,b_gpu,f_gpu,W,S_h_quant, block = (thread_strides, 1, 1),
grid = (block_size,1))
File
"/usr/local/lib/python2.6/dist-packages/pycuda-2011.1-py2.6-linux-x86_64.egg/pycuda/driver.py",
line 187, in function_call
func.launch_grid(*grid)
pycuda._driver.LaunchError: cuLaunchGrid failed: launch out of resources
My program is attached to the mail.
P.S. I'm new in CUDA so it's possible that I've just made some stupid mistake=)
Best regards,
Mikhail

I tried your program and it worked without error when i reduced thread_strides
and BLOCK_SIZE
to 256
