Inputs

kernel	a cl-kernel
args	sequence of cl-buffer or byte-array
sizes	sequence of integers
dependent-events	sequence of events

Outputs

event

a cl-event

Word description
Queue a kernel for execution with the given arguments. The sizes argument specifies input array sizes for each dimension. Dependent events can be passed to order the operation relative to other operations.
