Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: Threads of Single-Program Multiple-Data (SPMD) applications often execute the same instructions on different data.  propose the Dynamic Inter-Thread Vectorization Architecture (DITVA) to leverage this implicit data-level parallelism in SPMD applications by assembling dynamic vector instructions at runtime. DITVA extends an SIMD-enabled in-order SMT processor with an inter-thread vectorization execution mode. In this mode, multiple scalar threads running in lockstep share a single instruction stream and their respective instruction instances are aggregated into SIMD instructions. To balance thread-and data-level parallelism, threads are statically grouped into fixed-size independently scheduled warps. DITVA leverages existing SIMD units and maintains binary compatibility with existing CPU architectures. Our evaluation on the SPMD applications from the PARSEC and Rodinia OpenMP benchmarks shows that a 4-warp × 4-lane 4-issue DITVA architecture with a realistic bank-interleaved cache achieves 1.55× higher performance than a 4-thread 4-issue SMT architecture with AVX instructions while fetching and issuing 51% fer instructions, achieving an overall 24% energy reduction.
