MATLAB: Job monitor fails to update and slow down the matlab startup.

Question

I am using matlab 2014a. Now i have a issue for the job monitor of the parallel toolbox. It can not update job status. And every time i start up MATLAB, the program will take 3 minutes to initialize this module and gives the error message:

"An error has occurred while trying to update, unable to read MAT-file c:\user\**\Appdata\Roaming\MATLAB\local_cluster_jobs\task3102.out.mat "

How may i address this issue?

Answer 1

You might have some old corrupt jobs in the local cluster. You can delete the old jobs like this (presuming you don't need the data any more):

c = parcluster('local');
delete(c.Jobs);
