Is it 32 or 64 bit atchitecture? need to track down which kernel fails.

[artyom-beilis]

I also suggest to try AMD official drivers and not Mesa only.

I recall that for AMD 560 closed source drivers worked way better than Mesa ones. Also check of ROCm drivers still work on Fiji they are also better.

My CPU have 64 bit architecture.
GCN 3 (Fiji) - I don't know how many bit architecture.

Quote from AMD docs:

Every instruction is described with either 32 bits or 64 bits of microcode.
• Vector Memory instructions are 64 bits.
• Exports are 64 bits.
• LDS and GDS are 64 bits.
• Scalar ALU instructions are 32 bits but can have an additional 32 bits
of literal constant data.
• Vector ALU instructions can be 32 bits or 64 bits. The 32-bit versions
can have an additional 32 bits of literal constant data.

On AMD OpenCL from amdgpu-pro also error

Thank you! I got 8-9% speed impovement on amdgpu-pro OpenCL drivers.
