本文描述了一些非常早期的实验，新的体系结构，支持混合编程模型。我们的研究结果是有希望的，因为OpenMP线程与MPI交互的期望，允许使用的OpenMP不可知的工具。我们探讨了三种环境：一个“典型的”Linux集群，一个新的大规模的机器从SiCortex，和新的IBM BG/P，有相当不同的编译器和运行时系统的OpenMP和MPI。我们来看几个简单的诊断程序和一个“类应用程序”测试程序。我们展示了一个工具的使用，可以检查混合程序中事件的详细顺序，并说明混合计算可能并不总是按预期进行。
The paper describes some very early experiments on new architecturesthat support the hybrid programming model. Our results arepromising in that OpenMP threads interact with MPI as desired, allowingOpenMP-agnostic tools to be used. We explore three environments:a "typical" Linux cluster, a new large-scale machine from SiCortex, andthe new IBM BG/P, which have quite different compilers and runtimesystems for both OpenMP and MPI. We look at a few simple, diagnosticprograms, and one "application-like" test program. We demonstrate theuse of a tool that can examine the detailed sequence of events in a hybridprogram and illustrate that a hybrid computation might not alwaysproceed as expected.
