Parallel processing toobox not working on Ubuntu 18.04

8 views (last 30 days)
I have installed Matlab R2018a on a fresh install of Ubuntu 18.04. I can't get the parallel processing toolbox to work.
It seems to be correctly installed:
But when I try to open the parallel pool, I get "undefined function or variable":
And if I open the parallel processing "Manage Clusters" box, The dialog gets stuck on "Loading Profiles...":
All other toolboxes are working fine. `Parfor` loops run through in series, as if they were a normal `for` loop.
Any ideas what the problem is?

There are other toolboxes listed in your add-on explorer that also do not show up in ver.
rehash toolboxcache

Also, it's possible that the parallel computing toolbox is not installed correctly.
Can you please try to uninstall that toolbox (in Add-Ons->Manage Add-Ons-> Search for Parallel Computing Toolbox), then install that toolbox again (in Add-Ons->Get Add-Ons-> Search for Parallel Computing Toolbox)?
