Aap4all: An adaptive auto parallelization of serial code for hpc systems

High Performance Computing (HPC) technologies are emphasizing to increase the system performance across many disciplines. The primary challenge in HPC systems is how to achieve massive performance by minimum power con-sumption. However, the modern HPC systems are configuredbyaddingthe powerful and energy efficient multi-cores/many-cores parallel computing devices such as GPUs, MIC, and FPGA etc. Due to increasing the complexity of one chip many-cores/multi-cores systems, only well-balanced and optimized parallel programming technique is the solution to provide substantial increase in performance under power consumption limitations. Conventionally, the researchers face various barriers while parallelizing their serial code because they don’t have enough experience to use parallel programming techniques in optimized way. However, to address these obstacles and achieve massive performance under power consumption limitations, we propose an Adaptive and Automatic Parallel programming tool (AAP4All) for both homogeneous and heterogeneous computing systems. A key advantage of proposed tool is an auto recognition of computer system architecture, then translate automatically the input serial C++ code into parallel programming code for that particular detected system. We also evaluate the performance and power consumption while computing the proposed AAP4All model on different computer architectures, and compare the results with existing state-of-the-art parallel programming techniques. Results show that the proposed model increases the system performance substantially by reducing power consumption as well as serial to parallel transformation effort.
