Help with memory management

Another question, is there a way to call a kernel from another one? If its possible, is it quicker than launching a new kernel from host code? (the two kernels working with the same parameters, the new one needed only for syncronization purposes)

No, all kernels must be launched from the host. However, kernel launches are asynchronous, so you can queue them up to run in sequence without further host intervention.
