Compute units on emulator

Hi, I would like to say if the emulator considers the use of multiple compute units. I do not have a physical board for working, so if I had more than one compute unit, how does the emulator work?...

The CL_DEVICE_MAX_COMPUTE_UNITS value reported by the emulator or the FPGA itself is always "1", regardless of how many compute units you have in your kernel. This value depends on the characteristics of the OpenCL device (and not the kernel running on it) and it has no meaning in the particular case of FPGAs, since these devices do not have a fixed architecture.
