Parallel Computing Toolbox-Manage Cluster Profile

Hi everyone,

I am trying to use parallel computing toolbox (2014b version), but I couldn't organize manage cluster profile (all updates for java is working properly). When I click manage cluster profile, I get the following error in command window and I couldn't click any button (such as add, discover cluster or import) in cluster manager window.

In onether words, I couldn't use parallel computing toolbox in order to connect any cluster. I would greatly appreciate it if someone help me. Regards.

manage cluster profile inrunning jobs through the parallel computing toolbox and from time to time I receive java errors. For example, when I use the parcluster command, the following error comes up:

Could you please try removing your parallel.settings file? You can find it by running

>> prefdir

in MATLAB - it's in that directory. I would suggest renaming the old file to parallel.settings.bak to see if that helps.

Thank you for your time, but unfortunately it doesn't work. Do you have another suggestion ? Regards.

[Edric Ellis]

Sorry I don't have any other specific ideas - I'd suggest contacting MathWorks support.

[Nazif Çat?k]

Thank you Mr. Ellis. I have contacted with support team, but they don't reply so far. Regards.

Have you fixed it?

Any luck to resolve this problem?
