10 Minute Test # 4
October 1, 2009


1. (10) In CUDA we have seen that a grid is executed by call like
		foo<<<dimGrid, dimBlock>>>(a, b, c)
	How will this call be executed? Say as much as you can.














2. (10)	We are dealing with a system for which we can assume an M|M|1
	behavior. We are told that arrival rate is 4 jobs per second and
	that the utilization is 80%. 
	(a) What will be the response time?
	(b) What will be the average queue size?















3. (15) Write the code for the function
		char * longest(const char * s)
	which returns a pointer to the longest substring of s that consists
	of letters. So longest("aba-32  * salome(foo,3)") returns a pointer to the
	initial 's' of "salome".
