This project proposes runtime and compiler support that will enable programs to harvest idle SMPs and/or single processor workstations to perform parallel computations. The unique feature of this system is the ability to adapt parallel programs to the dynamic availability of processors while exploiting the locality within an SMP. The project integrates several goals, namely:1) Extend the Distributed Shared Memory, Strings, to support thread migration, incorporate adaptation to the changing number of available processors at runtime and propose techniques to balance data locality and the parallelism used when the number of processors changes at runtime. 2) Study the impact of eviction time on remapping strategies and constraints. 3) Develop compile-time support for parallel programs which can be executed in an environment where the number and the availability of the processors can change.4) Develop analytic models and extensively evaluate the above compiler and runtime techniques using several "real programs".5) Integrate the utilization of idle cycles for parallel computing on cluster of SMP workstations into the existing parallelization environment.

该项目提出了运行时和编译器支持，使程序能够收获空闲的SMP和/或单处理器工作站来执行并行计算。 该系统的独特之处是能够适应并行程序的处理器的动态可用性，同时利用SMP内的局部性。 该项目集成了几个目标，即：1）扩展分布式共享内存，字符串，以支持线程迁移，纳入适应不断变化的可用处理器数量在运行时，并提出技术，以平衡数据的本地性和并行使用时，处理器的数量在运行时的变化。 2)研究驱逐时间对重新映射策略和约束的影响。3)4）开发分析模型，并使用几个“真实的程序”对上述编译器和运行时技术进行广泛的评估。5）将SMP工作站集群上的空闲周期用于并行计算集成到现有的并行化环境中。
