[starpu-devel] Trouble with OpenCL+MacOS+STARPU+GCC+MPI

[Susana Munguia <susana.munguia56@gmail.com>]

Hello,

I am running on McOS 12.5, with 2 OpenCL devices. I am able to get other OpenCL applications to run, so I know it works independently. I have spent a long time debugging and reading. 

I have: 

-installed glib tools and glitbtoolize and change environment variables to them. 

-have read this old https://sympa.inria.fr/sympa/arc/starpu-devel/2011-02/msg00018.html thread on patches to get StarPU working on MacOS and have read through the files in 1.3 + master branch that seem to take care of this already. 

When I run StarPU_machine_display, I see that it identifies my OpenCL devices:

StarPU has found :

4 STARPU_CPU_WORKER workers:

CPU 1

CPU 3

No STARPU_CUDA_WORKER worker

I am able to run mpi StarPU examples. 

The issue is that basic examples with OpenCL fail. When I try to run examples with OpenCL calls, I get the same error of cannot locate their respective .cl kernel files. This same error steeps into applying StarPU to other known applications like ScalFMM. I would like to get OpenCL working to try out examples running on AMD GPU.

zsh: segmentation fault  STARPU_SCHED=dmdas ./block

Please let me know of something I can do to fix this. Or if there is another StarPU branch that avoids this error. 

Your help is appreciated.
