Hi Zach, So a tool like opencl-info:
https://github.com/marchv/opencl-infoshould be able to tell you what your hardware supports. However, these issues are unusual and not something we have observed with other platforms.

Hi Zach, You can try setting the 1D block size to 128 which will override the default of 64 (which is already quite large). Regards, Freddie.

I was able to get something started using the Gmsh plugin, and then importing the mesh into PyFR’s format. I’ll have a developer look into it. On another unrelated note, how do you determine the appropriate local work size for one dimensional and two dimensional pointwise kernels for a given graphics card using the OpenCL backend (i.e. where does one find appropriate values for local-size-1d and local-size-2d)?
