Vector left Shifting is the operation of

shifting the elements of a single

dimensional array to

the left by one position keeping the last

(boundary) element unchanged. Write a

shift vector

kernel and the host stub function. The

code must be written and run on a

proper environment

setting, then you need to submit it to

your TA. Assume that the vector length

is 2000, each

thread calculates one output element,

and the thread block size is 512 threads.
