Abstract. We present Functory, a distributed computing library for Objective Caml. The main features of this library include (1) a polymorphic API, (2) several implementations to adapt to different deployment scenarios such as sequential, multi-core or network, and (3) a reliable fault-tolerance mechanism. This paper describes the motivation behind this work, as well as the design and implementation of the library. It also demonstrates the potential of the library using realistic experiments.
Abstract-In this paper, we discuss results and characteristics of the benchmark suites maintained by the Standard Performance Evaluation Corporation's (SPEC) High-Performance Group (HPG). Currently, SPEC HPG has two lines of benchmark suites for measuring performance of large-scale systems: SPEC OMP and SPEC HPC2002. SPEC OMP uses the OpenMP API and includes benchmark suites intended for measuring performance of modern shared memory parallel systems. SPEC HPC2002 uses both OpenMP and MPI, and thus it is suitable for distributed memory systems, shared memory systems, and hybrid systems. SPEC HPC2002 contains benchmarks from three popular application areas, Chemistry, Seismic, and Weather Forecasting. Each of the three benchmarks in HPC2002 has a small and a medium data set, in order to satisfy the need for benchmarking a wide range of high-performance systems. We analyze published results of these benchmark suites regarding scalability. We also present current efforts of SPEC HPG to create new releases of the benchmark suites.
