--- Comment #8 from Vedran Miletić <vedran at miletic.net> ---
I have made some progress with clBLAS by implementing clEnqueueFillBuffer()
from OpenCL 1.2 [1] (have to clean up and post the patch, will do soon). Test
makes it a bit further now:

$ test-short 
Initialize default OpenCL and clblas...
SetUp: about to create command queues

Test environment:

Device name: AMD FIJI (DRM 3.8.0 / 4.9.14-200.fc25.x86_64, LLVM 5.0.0)
Device vendor: AMD
Platform (bit): Linux
clblas version: 2.12.0
Driver version: 17.1.0-devel
Device version: OpenCL 1.1 Mesa 17.1.0-devel (git-0c3fbf8)
Global mem size: 7984 MB
---------------------------------------------------------

[==========] Running 10096 tests from 125 test cases.
[----------] Global test environment set-up.
[----------] 4 tests from TRSM_extratest
[ RUN      ] TRSM_extratest.strsm
[       OK ] TRSM_extratest.strsm (813 ms)

clBLAS is required (at least) for Octopus and Theano. I expect to get it
working over the coming months, hopefully along with improving clBLAS, fixing
stuff like [2, 3].
