MATLAB: Does MJS fail to start with an unknown host error

MATLAB Parallel Server

I have installed MATLAB Parallel Server, and I am using MATLAB Job Scheduler as my scheduler for the cluster. However, I am unable to start MJS. Why does MJS fail to start with an unknown host error?

Best Answer

This error indicates that the hostname that is specified in your MATLAB Parallel Server configuration cannot be properly resolved. Check your DNS settings on the machines used in the cluster to verify that they report the correct hostname. Additionally, insure that each machine is able to communicate with each other, and that each machine is able to resolve the hostnames of other machines to the correct IP addresses.
If you are unable to resolve this error message, contact MathWorks Licensing and Installation Support for assistance.
