摘要

到目前为止，元计算大多是在或多或少的静态配置中完成的。然而，具有动态不规则行为的应用越来越重要，计算平台往往是具有不同系统负载的分时环境。因此，动态连接和动态工作负载迁移的可能性变得越来越重要。本文讨论了一种利用标准并行库MPI实现异步工作负载平衡的方法。MPI和线程通常生活在或多或少分离的世界中，MPI-2的线程扩展主要是为了更有效地利用模型中的每个SMP节点，而模型中的大部分仍然是SPMD。我们通过动态机制扩展了MPI，以便在线程和动态状态/资源监控的基础上自动平衡工作负载。我们的扩展库TeMPI旨在以MPICH的最小版本运行，从而在Globus网格环境中运行MPICH- g2。

Towards asynchronous metacomputing in MPI

Metacomputing so far has been done mostly in more or less static configurations. However, applications with dynamic irregular behavior are increasing in significance and the computing platforms more often are time-sharing environments with varying system load. Thus, possibilities for dynamic connection and dynamic workload migration are becoming important. The paper discusses an approach to perform asynchronous workload balancing using the standard parallel library MPI. MPI and threads typically live in more or less separated worlds and the thread extension of MPI-2 is mainly meant to exploit more efficiently per SMP node within a model which is still mostly SPMD. We have extended MPI by dynamic mechanisms to automatically balance workload on the basis of threads and dynamic status/resource monitoring. Our extended library TeMPI is designed to run with in a minimum version with MPICH and thus MPICH-G2 in the Globus grid environment.
