WebAs kernel code gets more complex, some work-items need to wait until other work-items complete. Example: 16 work items do a vector-multiply and store the result in local memory. 1 of those work items accumulates the products (after all 16 finish the multiply) Pipes. Enabling “deep” parallelism across kernels. Very important for FPGAs WebEvents can be used to identify commands enqueued to a command-queue from the host. These events created by the OpenCL runtime can only be used on the host i.e. as events passed in event_wait_list argument to various clEnqueue APIs or runtime APIs that take events as arguments such as clRetainEvent, clReleaseEvent, clGetEventProfilingInfo. how many sides does a oval have https://primalfightgear.net
