Re: [Starpu-devel] Problème sur SOCL

[Sylvain HENRY <sylvain.henry@inria.fr>]

Please try the following:

1) ICD
- Check that /etc/OpenCL/vendors/socl.icd exists
- Check that it contains the path to the correct libsocl-1.*.so
- Check that there is no additional blank line at the end

2) OpenCL on CPU
- Check that the environment variable is set STARPU_OPENCL_ON_CPUS=1
- For AMD implementation, set STARPU_DISABLE_ASYNCHRONOUS_COPY=1
- Check that StarPU OpenCL examples (without SOCL) work

3) Try to install and to link with another libOpenCL such as ocl-icd 
(https://forge.imag.fr/projects/ocl-icd/)


From your other mail, it seems that your ICD is correctly configured. 
Please check (2) above.

Regards
Sylvain
