OpenCL on nvidia-361 with async_pixelpipe and use_pinned_memory set to
TRUE takes 107s to export (instead of 124s previously). The output is on
Dropbox.
So there is definitely a problem with nvidia-361. I noticed there is no
package nvidia-361-uvm, maybe a cause ?
Moreover, I have now an error with atrous :
[opencl_atrous] couldn't enqueue kernel! -4
[default_process_tiling_opencl_ptp] couldn't run process_cl() for module
'atrous' in tiling mode: 0
[opencl_pixelpipe] failed to run module 'atrous'. fall back to cpu path

For now I deleted nvidia-361 driver and switched to nvidia-340 (340.96).
So my export time with OpenCL dropped from 124s to 27-30s (5-8s better
than CPU). The output is updated here :

Those timings look much more reasonable. About 9 seconds are spent in
OpenCL kernels. The rest is spent in several non-OpenCL modules (e.g.
colorin/colorout with LittleCMS2, defringe which lacks OpenCL atm).
