There is my PC device, is it unavailable for the program? The exclusion results show it does not support double precious.

print(cl.get_platforms())
print(cl.device_type.ALL)
print(cl.device_type.GPU)
print(platform.get_devices(device_type))
print(cl.Context([device]))

Hello Quanzhang, thank you for your question.

What happens when you run example2 (the OpenCL example)? Could you post a full error message, or does the OpenCL code work just fine?

When you run the tests, via pytest in the repo directory, do the OpenCL integrator tests pass?

Attached I give my installation records.

I used the code platform Pycharm with python 3.9 to install the program in Window 10. Only Installing via wheels (https://www.lfd.uci.edu/~gohlke/pythonlibs/#pyopencl) is successful.
• Install PeriPy pip install peripy
When I executed this code, problem occurs. ValueError: 'XX.pyx' doesn't match any files. The problem is similar to this one.
https://stackoverflow.com/questions/60717795/python-setup-py-sdist-with-cython-extension-pyx-doesnt-match-any-files
I also use “python setup.py install” to avoid this problem.

Try running pytest peripy from the peripy directory, not peripy_master, what happens?

There is no difference.

Do you get to choose this devicepyopencl.Device 'Intel(R) Iris(R) Xe Graphics' on 'Intel(R) OpenCL HD Graphics' at 0x19ad52444d0'
upon running the example2?
and what about python example1/example.py --opencl

I will suggest changing the code

peripy/integrators.py::Integrator::__init__::line 42
self.context = get_context()
into
self.context = cl.create_some_context()

and then you should be able to choose a device. What devices are listed? What happens when you try each of them?

Thanks for this, what about testing for double_fp_support? Does this raise the ValueError?

qianzhang1994 Oct 25, 2021
Author

Yes, it will raise the ValueError

bb515 Oct 25, 2021

Okay thanks for this, two things then

It seems like your GPU does not support double precision. Single precision has not been tested on PeriPy and so we can't recommend using it as it may lead to numerical instabilities. You could try removing the double precision boiler plate code (at your own risk) to see if it runs a simulations with single precision. If you are looking to use PeriPy for numerical simulations I recommend using a GPU that supports double precision.
The correct code behaviour is to raise this ValueError for your device when get_context() logic branch is used. I will make an issue to resolve this incorrect code behaviour: not raising the ValueError.

Thanks for your help. I will try to find a new device with available GPUs.
