Connectivity Testing
For testing connectivity between the client machine and the machines of your compute
cluster, you can use Admin Center. For more information about Admin Center, including
how to start it and how to test connectivity, see “Start Admin Center” and “Test
Connectivity” in the MATLAB Distributed Computing Server documentation.
Hostname Resolution
If a worker cannot resolve the hostname of the computer running the MATLAB client,
use pctconfig to change the hostname by which the client machine advertises itself.
Socket Connections
If a worker cannot open a socket connection to the MATLAB client, try the following:
• Use pctconfig to change the hostname by which the client machine advertises itself.
• Make sure that firewalls are not preventing communication between the worker and
client machines.
• Use pctconfig to change the client's pmodeport property. This determines the port
that the workers will use to contact the client in the next pmode session.
