我最近开始使用COMPS。我正在遵循其中一个文档示例，但似乎无法正常工作。
我正在尝试运行提供的matmul示例应用程序，并且正在使用以下命令:
runcompss --classpath=./matmul.jar matmul.files.Matmul 4 1
但是，我得到以下输出:
Using default location for project file: /opt/COMPSs/Runtime/scripts/user/../../configuration/xml/projects/project.xml

是什么导致此错误？
谢谢!
最佳答案
classpath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
