PetaFlop Kernel:a),b)Unit and Large Stride Vector Fetch and Store

PetaFlop Kernel:a),b)Unit and Large Stride Vector Fetch and Store

• In the first three kernels (a) (b) (c), n = 10^8; arrays are presumed appropriately dimensioned.
• a). SAXPY loop
• do i = 1, n
  • c(i) = 3.141592653589793 * a(i) + b(i)
• enddo
• b). Large-stride vector fetch and store
• do i = 1, n
  • b(131*i) = a(131313*i)
• enddo
