COMPSs application blocked

When executing the sample application increment given in the manual (http://compss.bsc.es/releases/compss/latest/docs/COMPSs_User_Manual_App_Exec.pdf) the runtime gets blocked and no error message is displayed in the terminal.

OUTPUT: 

$ runcompss increment.Increment 3 1 2 3
Using default location for project file: /opt/COMPSs/Runtime/configuration/xml/projects/project.xml
Using default location for resources file: /opt/COMPSs/Runtime/configuration/xml/resources/resources.xml

----------------- Executing increment.Increment --------------------------

WARNING: IT Properties file is null. Setting default values
[   API]  -  Deploying COMPSs Runtime v1.3 
[   API]  -  Starting COMPSs Runtime v1.3
Initial counter values:
- Counter1 value is 1
- Counter2 value is 2
- Counter3 value is 3

How can I know what is blocking my application?

Thank you in advance

EDIT: Checking the $HOME/.COMPSs/increment*/runtime.log all the tasks seem to be blocked:

grep "Blocked" runtime.log 
[(410)(2016-03-04 15:48:09,864)       TaskScheduler]    @scheduleTask     -  Blocked: Task(1, increment) 
[(411)(2016-03-04 15:48:09,865)       TaskScheduler]    @scheduleTask     -  Blocked: Task(2, increment) 
[(412)(2016-03-04 15:48:09,866)       TaskScheduler]    @scheduleTask     -  Blocked: Task(3, increment)
Solution

  • The runtime.log must be in the home folder of the user who has executed runcompss

    $HOME/.COMPSs/increment*

    EDIT: If all tasks are blocked, check if there are constraints defined in IncrementItf.java matches with the description in the resources.xml. Another possible problem is that the resources couldn't be started.
