I am sorry, the problem with reduction was actually in VexCL. VexCL
generates different reduction kernels for CPUs and for GPUs. pocl sets
device type to CL_DEVICE_TYPE_DEFAULT | CL_DEVICE_TYPE_CPU, so my CPU
device was incorrectly determined as a GPU (or rather as not a CPU).
I've already fixed the issue here:
https://github.com/ddemidov/vexcl/commit/7d3c2ae53d77af169131e66a5bb03574ca8cf2f1.
Tests in VexCL that use reduction are now passing. Boost.compute
interaction tests and one of stencil convolution tests are still failing.
