where can I see the openCL file? about coriander HOT 3 OPEN

Well.. the opencl is generated at runtime, not at compile time. This is because we only find out a lot of key type and address space information at runtime.

You can dump the opencl files at runtime though, by doing export COCL_DUMP_CL=1, see https://github.com/hughperkins/coriander/blob/master/doc/options.md

ok..thanks a lot !
besides, suppose I don't have any gpus, and I want to run it on a cpu, how can I change the config from gpu to cpu? Surely I know it might encounter some problems, but I still want to give it a try :-P

Since in your another project : https://github.com/hughperkins/tf-coriander/ , I have tried it on a cpu, and it does work.

thanks for your attention~

What do you mean by 'run on a cpu'? Coriander will work only on OpenCL 1.2 devices. If you want to run it on an OpenCL 1.2 CPU, bearing in mind it wont actually run, because the workgroup sizes are too big, but if you want to tweak the workgroup sizes, you'd need to hack on this line, https://github.com/hughperkins/coriander/blob/master/src/cocl_context.cpp#L43

       cocl::CoclDevice *coclDevice = cocl::getCoclDeviceByGpuOrdinal(gpuOrdinal);

which calls into https://github.com/hughperkins/coriander/blob/master/src/cocl_device.cpp#L108-L120

...and modify something about this so it can return CPU OpenCL devices, instead of just GPU OpenCL devices. As you state, this wont work very well though, and you'll need to hack around with workgroup sizes and so on.
