  1. The PARSEC Benchmark Suite 발표자 이보선 Characterization and Architectural Implications

  2. MOTIVATION • The existing benchmark suffer from a number of limitations and are not adequate to evaluate future CMPs • The lack of good benchmark suites can hamper parallel architecture research as well as reduce its impact. • It includes not only a number of important RMS applications but also several leading-edge applications from Princeton University, Stanford University, and the open-source domain.

  3. Limitations of Existing Benchmark Suites • SPLASH-2 • SPEC CPU2006 and OMP2001 • Other Benchmark Suites

  4. Requirements for a Benchmark Suite- Objectives of PARSEC • Multithreaded Applications • Emerging Workloads • Diverse • Employ State-of-Art Techniques • Support Research

  5. PARSEC BENCHMARK SUITE • It consists of 9 applications and 3 kernels • PARSEC workloads were selected to include different combinations of parallel models, machine requirements and runtime behaviors • All benchmarks are written in C/C++ • PARSEC meets all the requirements outlined

  6. PARSEC - Input Sets • Test - A very small input set to test the basic functionality of the program. • Simdev - A very small input set which guarantees basic program behavior similar to the real behavior, intended for simulator test and development. • Simsmall, Simmedium and Simlarge- Input sets of different sizes suitable for simulations. • Native - A large input set intended for native execution.

  9. Experimental Setup • We used CMP$im for our workload characterization. • We simulate a single-level cache hierarchy of a CMP and vary its parameters. • All experiments were conducted on a set of Symmetric Multiprocessor (SMP) machines with x86 processors and Linux. • shared 4-way associative cache (4 MB capacity and 64 byte lines) • By default the workloads used 8 cores. • The programs were compiled with gcc 4.2.1.
