cannot run gas dynamic example in GPU

[samech-git]

Dear pySPH developers,

I would like to express my gratitude for your hard work and dedication in developing pySPH. I have found this software very helpful in performing computational fluid dynamics simulations.

However, I have encountered some issues while attempting to run certain simulations using pySPH in GPU. Specifically, I can run "python cube.py --opencl" correctly, but when attempting to run the Kelvin-Helmholtz instability simulation in the gas dynamics folder using the command "python kelvin_helmholtz_instability.py --opencl", I received an error message: "clBuildProgram failed: BUILD_PROGRAM_FAILURE".

(base) [samech@admin gas_dynamics]$ cat kh.log |grep error -A 2
self._prg, was_cached = self._build_and_catch_errors(
File "/public/home/samech/anaconda3/lib/python3.9/site-packages/pyopencl/init.py", line 580, in _build_and_catch_errors

I have attached the relevant error messages from the log file for your reference. I believe this issue may be related to an ambiguous function call or overloadable attribute in the kernel code, but I am not sure how to proceed with resolving it.

I would greatly appreciate any assistance you can provide in resolving this issue so that I can continue to use pySPH effectively. Thank you for your time and attention.

Sincerely,
Samech
