Heterogeneous multiprocessor/multicore 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.
| Application | Description |
|---|---|
| Molecular Dynamics | Simulating molecular dynamics when molecules are shot to surfaces of solid atoms. Developed with Prof. Wenjing Ye. |
| Ray Tracing | 3D scenes rendering. Developed with Prof. Pedro Sander. |
| Ultrasound | Medical diagnostics using 2D/3D ultrasound imaging. Developed with Prof. Weichuan Yu. |
| LDPC | Low-density parity-check code encoder. Developed with Prof. Wai Ho Mow. |
| TURBO | Turbo code decoder. Developed with Prof. Wai Ho Mow. |
| Reed-Solomon | Reed-Solomon code encoder and decoder. |
| FFT | Fast Fourier Transform with complex number inputs. |
