Hi,
Now I am testing pocl (v0.8) with Rodinia benchmark suite. I tried to compile
and run the {backprop} in Rodinia.
This benchmark {backprop} is using {CL_DEVICE_TYPE_GPU} in default (see line
115 of backprop_ocl.cpp), so we need to change it manually. After changing it
to the CPU type, it then encountered the kernel compiling error as follows.
When looking into the kernel backprop_kernel.cl, I found that the kernel tries
to call two functions: log2() and pow(). Since I know that these two functions
are the build-in function of OpenCL specification, I guess there might be
something wrong with the implementation?
Regards,
Jianbin
