Parpool won't start anymore

All of the sudden parpool will not start. After hours of trying it does not succeed.

It has run without problems for months and months. I usually run the 'local' profile

Only changes made recently, was addition of new Win 10 user, and addition of a startup.m file for the original user (otherwise matlab would also f*** up starting properly.

Computer has been restarted thrice, but matlab can't start parpool.

Any clues?

I also can't validate the local profile. It gets stuck in createJob (second task)

Maybe not a solution to my problem, but is there any way I can find out what might be wrong.

I have tried starting the parallel pool for 55 hours until I killed it.

Hello Mads,

I am wondering whether you managed to resolve this issue? As I am currently also experiencing this!

Kind regards,

Nicos

Not, directly. Although, I don't have the problem since I switched OS to Ubuntu in the mean time.

Hi @Mads,

Is issue resolved? I'm also facing similar problem with MATLAB2019b

[Xin Niu]

same for MATLAB 2023a and b. I need to uninstall Parallel Compute Toolbox every time I restart MATLAB.
