title: opencl:can different queues on the same device execute kernels in parallel?
body: <p>I created 2 queues on a GPU device,and want to execute the kernels in parallel.This is no need to set events between kernels in different queues,but the kernels in tne same queue must be executed in order.In addition,I created 2 CPU threads,each CPU thread control 1 queue,and the CPU threads are executed parallel.Now It seems that the kernels between different queues were not executed in parallel.So anybody can give me some advices?</p>
