clCreateCommandQueue (-6) about silentarmy

I went back to the AMD forum and found this thread that recommended setting these environment variables:

export GPU_FORCE_64BIT_PTR=1
export GPU_USE_SYNC_OBJECTS=1
export GPU_MAX_ALLOC_PERCENT=100

Tried it, and successfully ran sa-solver.

I'm having the same issue with a Radeon HD 7870. According to these threads on the AMD community forum, there is a know issue with OpenCL + AMDGPU PRO driver on certain graphics cards:

Pitcairn graphics card doesn't work with AMDGPU-PRO 16.60 driver
OpenCL clCreateCommandQueue() fails with error -6(out of host memory) on Ubuntu 16.04.3 64 bit, AMDGPUPRO driver 17.30 465504

Solution above me seems to be working, but in blender results of opencl calculations seem to be wrong for me. Are you sure that nothing is wrong with your computations?

EDIT: I have found workaround for blender (progressive rendering has to be used).
