ispc: A SPMD Compiler for High-Performance CPU ProgrammingMatt Pharr Intel Corporationmatt.pharr@intel.comWilliam R. Mark Intel Corporationwilliam.r.mark@intel.comABSTRACT SIMD parallelism has become an increasingly important mechanism for delivering performance in modern CPUs, due its power efficiency and relatively low cost in die area com- pared to other forms of parallelism. Unfortunately, lan- guages and compilers for CPUs have not kept up with the hardware’s capabilities. Existing CPU para
