Parpool works on 2014b but not on 2015a

The error message when I try to validate my local profile on 2015a is shown below.

I have both 2014b and 2015a installed right now and I re installed 2015 already. I only have malware bytes and the firewall settings are fine.

I would appreciate a quick answer as I am quite annoyed that in hopes of expecting less bugs from the update I encountered a new one, and I won't make space on my hard drive for both for very long.

Thanks a lot in advance, Nat

I have the same issue. I've tested 2015a on 2 different computers and both faulted with the same error as above. There were no issues with a 2014b install on one of the computers. Submitted query to MathWorks and will post any info when I get it.

The MathWorks support people had the following suggestion that worked for me on both installs:

"Thank you for contacting MathWorks Installation and Licensing Support. There are a few things that can cause the local scheduler to fail validation. The most common cause is the new local mpiexec implementation. Try the following command to disable this feature:

distcomp.feature( 'LocalUseMpiexec', false )"

That did the trick, but the line must be entered every time matlab starts, so to make it permanent support said:

"I suggest adding the command to your startup.m file. This will be located in your MATLAB working directory. Run the below to find any existing startup.m files:

which -all startup.m

If you do not have any, create one in your MATLAB working directory with the below inside:

distcomp.feature( 'LocalUseMpiexec', false ) "

Hope that helps. Support also said it could be bad local scheduler data that needs to be cleared.

Thanks so much! When I get the time to install 2015 again I will test this.

This is definitely not expected, and might be an installation problem or similar. I suggest contact MathWorks support directly to help overcome this problem.
