COMPSs runco​​mpss错误。不能运行MATMUL示例应用程序在本地

Question

我一直在使用COMPSs最近开始。我正在关注其中一个文档示例，但似乎没有奏效。

我试图运行提供MATMUL示例应用程序，我使用这个命令：

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

不过，我得到以下输出：

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

什么导致这个错误？

谢谢！

Answer 1

类路径选项必须是绝对路径到您的jar文件。

例如，如果matmul.jar位于$HOME/workspace_java/matmul/jar/路径下，你应该执行：

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

Answer 2

它看起来像一些错误任务的执行正在发生的事情。你是否检查过runtime.log或任务的标准输出/错误？
