Could you explain a bit more on this multi-core parallelism requirement of
OpenCL?
[/quote]
A typical opencl kernel looks like
```c
__kernel void helloworld(__global char* in, __global char* out)
{
int num = get_global_id(0);
out[num] = in[num] + 1;
}
```
, where get_global_id fetches the id of a global dimension, and kernel would
utilize available hardware threads to compute along such dimension.
In addition, while OpenCL is originally designed to target general-purpose
computing and the design of VTA is domain-specific, I think bridging OpenCL
software stack into VTA hardware design would bring a lot of issues, and would
degrade the actual performance.
