Hi everybody,
I tried installing the Parallel Computing Toolbox version R2013b. When I try to start parpool locally I get the error message:
Error using parpool (line 111)
Failed to start a parallel pool. (For information in addition to the causing error, validate the profile 'local' in the Cluster
Profile Manager.)
Error in parallel.internal.ui.PoolHelper.startPool (line 11)
parpool();
Caused by:
Error using parallel.internal.pool.InteractiveClient/start (line 326)
Failed to start pool.
Error using parallel.Cluster/createCommunicatingJob (line 82)
The property "NumWorkersRange" cannot be set after submission.
Validating the local profile also fails at the following stages:
*Stage: Job test (createJob)*
Status: Failed
Description:The validation stage encountered a MATLAB exception.
Command Line Output:(none)
Error Report:
Tasks can only be added to jobs which are in state 'pending'.
Debug Log:(none)
*Stage: SPMD job test (createCommunicatingJob)*
Status: Failed
Description:The validation stage encountered a MATLAB exception.
Command Line Output:(none)
Error Report:
The property "NumWorkersRange" cannot be set after submission.
Debug Log:(none)
I already searched the web but couldn't find an answer. Can anybody please help me whit this?
Thank you very much!
Best;
Martin
Edit:
forgot to mention: I'm working on a 64bit Debian machine, if that info is needed

I have a similar problem, too. I use a cluster to run parallel jobs, and 7 out of 13 almost identical jobs (but reside in different folders) failed and gave this error message:
Error using batch (line 176) Tasks can only be added to jobs which are in state 'pending'. Undefined function or variable 'job'.
Does anyone have a clue? I asked this question to the tech people at the computing center but so far I received no reply.
Thanks.
