TLP 4 • Assume that a kernel has 256-thread Blocks, 4 independent instructions for each global memory load in the thread program, and each thread uses 10 registers, can fit 3 blocks global loads have 400 cycles – 4 cycles * 4 inst * 24 warps = 384 < 400 • If a compiler can use one more register to change the dependence pattern so that 8 independent instructions exist for each global memory load, can only fit 2 blocks – 4 cycles * 8 inst * 16 warps = 512 > 400, better hiding memory latency
