COMPSs runcompss error. Can't run the matmul example app locally

Question

I have recently started using COMPSs. I am following one of the documentation examples, but it doesn't seem to be working.

I am trying to run the provided matmul example app and I am using this command:

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

However, I get the following output:

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

What could be causing this error?

Thank you!

It looks like something wrong is happening in the execution of tasks. Have you checked the runtime.log or the standard out/err of the task?

Where are those files? The output says they are supposed to be in this directory ''/home/vanton/.COMPSs/matmul.files.Matmul_08/jobs/", but there's nothing there, the directory does not even exist... – Victor Anton Mar 04 '16 at 15:13

You have to run with the debug option: `runcompss -d` – Jorge Ejarque Mar 04 '16 at 15:15

You can enable the debugging logs by passing a CLI argument to the execution. Unix format: `runcompss -d`. GNU format: `runcompss --debug=debug_level` where debug_level = [off | info | debug] – Pol Alvarez Vecino Mar 04 '16 at 15:20

Oh now I see the files! There's an error printed there: integratedtoolkit.nio.exceptions.JobExecutionException: Can not get class by reflection Caused by: java.lang.ClassNotFoundException: matmul.files.MatmulImpl – Victor Anton Mar 04 '16 at 15:20

The classpath option must be an absolute path to your jar file.

For example, if the matmul.jar is located under the $HOME/workspace_java/matmul/jar/ path, you should execute:

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