Hi,

I am running into the fatal error in MPI innit as mentioned on the MATLAB FAQ. As suggested, I have created

nano $ISSM_DIR/etc/hosts

and added my machine name: e.g.,

127.0.0.1 esacXXXXXXXX

But after restarting MATLAB I run into the same error. I have tried running a number of the nightly tests that previously worked fine...

My machine is an M1 Mac, recently updated by my IT department... I don't have sudo privileges.

Best wishes,
Adam

    adamjhepburn Hi Adam,
    The file you need to edit is /etc/hosts, not $ISSM_DIR/etc/hosts. I don't believe you can do this without sudo, but if you have the ability, you could create a new account on this computer with Admin privileges, edit the file, then switch back to your other user.

        The one in private/etc/hosts? Just checking because it starts with:

        `##

        Host Database

        #

        localhost is used to configure the loopback interface

        when the system is booting. Do not change this entry.

        ##
        127.0.0.1 localhost
        255.255.255.255 broadcasthost
        ::1 localhost'

        and I want to be sure...
