Parallel thread execution based on thread id

[Altera_Forum]

Hi, 

 I was looking to execute different instructions by threads depending on the thread in parallel.   Example, if there are 4 instructions, I1,I2,I3,I4 , and I want thread 1 should execute I1, thread 2 execute I2, and so on, in parallel - how could I do it with the help of this tool?   Thanks.

Look at the available work-item functions of get_global_id(uint D), get_global_size(uint D), get_local_id(uint D), get_lobal_size(uint D), etc.   Once you have the thread ID numbers you can then branch off and execute your different instructions.

Hi,  

I have done it. But the issue is that this design carries out the instructions and only the output is muxed according to the thread id. This means that the latency for the final output increases. Any other input?      --- Quote Start ---  It's definitely possible if you're running an NDRange kernel.
