matlab parallel job shows unavailable

Just starting out with using the parallel toolbox. running matlab2013b on ubuntu 12.04 I tried the following commands, shown alongwith their outputs:

c=parcluster('local') c =

 Local Cluster

    Properties: 

                          Profile: local
                         Modified: false
                             Host: Vyom
                       NumWorkers: 4

               JobStorageLocation: /home/aniket/jobstorage/
 RequiresMathWorksHostedLicensing: false

    Associated Jobs: 

                   Number Pending: 0
                    Number Queued: 0
                   Number Running: 0
                  Number Finished: 0

j=createJob(c)

j =

 Invalid Job ID 18 Information
                 Type: independent
                State: unavailable

Basically any job i create shows unavailable, could you please help me out?

Very strange. Can you check that you have correct read/execute/write permissions for the directory '/home/aniket/jobstorage'?

Hi,

Can you try deleting all existing jobs and then create a new job?

>> mycluster=parcluster(‘local’);

>> delete(mycluster.Jobs);

This could also be an installation problem. When I executed the command j=createJob(c) on a Ubuntu 13.04, this is what I obtained:

Host: '……………..'

HasSharedFilesystem: 1

RequiresMathWorksHostedLicensing: 0

JobStorageLocation: '/home/user_name/.matlab/local_cluster_jobs/Matlab_ver'

ClusterMatlabRoot: ‘………………………………..'

LicenseNumber: ''

OperatingSystem: 'unix'

NumWorkers: 2

Type: 'Local'

Profile: 'local'

UserData: []

Jobs: [1x1 parallel.job.CJSIndependentJob]

Looks like you are missing a few outputs. Have you tried validating your cluster profile? Here is a link to help you out:
