Heterogeneous multiprocessor/multicore/manycore systems are promising alternatives to traditional homogeneous multiprocessor systems and can potentially offer better tradeoffs among energy efficiency, performance, flexibility, scalability, and cost. However exploring their heterogeneities is not well supported by traditional benchmarks which rely on compliers and operating systems developed for homogenous multiprocessor systems. To overcome these issues, this project developed a heterogeneous multiprocessor benchmark suite called COSMIC (Communication-Observant Schedulable Memory-Inclusive Computation).

COSMIC is systematically developed from the algorithms of typical multiprocessor applications. Besides implementing the applications in high-level programming languages, COSMIC uses a formal computational model TCG to explicitly capture the computation and communication requirements of multiprocessor applications. It provides a tool to automatically allocate memory and partition and schedule tasks based on user-defined methods.
COSMIC heterogeneous multiprocessor benchmark suite currently includes the following main components and set of applications.
|Cifar-train||Training phase of a Deep Convolutional Neural Network for the Cifar-10 dateset.|
|Facerec-train||Training phase of a Deep Convolutional Neural Network for face recognition.|
|AlexNet-inf||Interfence phase of the DCNN with 5 convolutional layers.|
|Machine Learning - ALIP||Machine learning based image indexing.|
|Machine Learning - FMP||Financial market prediction using machine learning.|
