This paper presents PEMAP, an automated performance estimation tool to project performance of hand-parallelized programs from sequential programs and BEMAP, a benchmark suite to measure an auto-parallelizer or even a machine's performance. BEMAP is an open-source project, and the documentations on code explanations and experimental results are also provided. Our experiments on PEMAP shows we can estimate performance of hand-parallelized programs in an error of 0.44% of sequential program's performance on average, while using BEMAP shows that the ability of an auto-parallelizer can be measured by comparing the compiled code to the handtuned parallelized OpenCL code, and therefore assisting the development of the auto-parallelizer tool.
