Syntactic constructs to prevent any dead code elimination on the kernel.Non-null data initialization, and live-out data dump.It performs extra operations such as cache flushing before the kernel execution, and can set real-time scheduling to prevent OS interference. A single file, tunable at compile-time, used for the kernel instrumentation.The purpose is to uniformize the execution and monitoring of kernels, typically used in past and current publications. PolyBench is a collection of benchmarks containing static control parts.
