COMPSs runcompss错误无法在本地运行matmul示例应用程序

Question

我最近开始使用COMPSs。我正在学习其中一个文档示例，但它似乎不起作用。

我正在尝试运行提供的matmul示例应用程序，并使用以下命令：

runcompss --classpath=./matmul.jar matmul.files.Matmul 4 1

但是，我得到了以下输出：

Using default location for project file: /opt/COMPSs/Runtime/scripts/user/../../configuration/xml/projects/project.xml

Using default location for resources file: /opt/COMPSs/Runtime/scripts/user/../../configuration/xml/resources/resources.xml

是什么导致了这个错误？

谢谢!

Answer 1

类路径选项必须是jar文件的绝对路径。

例如，如果matmul.jar位于$HOME/workspace_java/matmul/jar/路径下，则应执行：

runcompss -d --classpath=$HOME/workspace_java/matmul/jar/matmul.jar matmul.files.Matmul 4 1

在执行任务的过程中，似乎出现了一些问题。您是否检查了任务的runtime.log或标准输出/错误？
