Distributive Toolbox: 3 core connect, 1 core failed to connect

Distributive Toolbox: 3 core connect, 1 core failed to connect

Post by Ian » Tue, 14 Sep 2010 17:44:05


Hello,

-Ubuntu head server.
-Windows cluster of 10 quad cores.
-In admin center, in the 'workers' section under 'connection', 1 quad core shows, 3 cores connect successfully (3 workers), 1 core states "failed to connect".
-Restarting doesn't change the connection. Status remains idle.

Why does one core fail to connect?

I don't think anyone will be able to diagnose this issue with just the
information you provided; I suggest you contact our Australian office's
Technical Support staff and work with them to troubleshoot this issue.

[SOLVED]
Hi Steve,
-Thanks for the MATLAB tech support plug.
-Gregory consulting was able to solve it.
-Admin 101.
i.) Uninstall MATLAB
i.ii.) Manually deleting the left over files in [MATLAB]\matlab2010a.
i.iii.) Manually delete any log files if exist relating to the distributive process.
ii.) Fresh install.

NOTE: The reason I performed the above also is because I changed the 'hostname' on Ubuntu head node and for some reason the old name is remembered on slaves and '-clean' didn't help.
NOTE: The mdce service seems finicky. Meaning, make sure all PC's can ping each other through the firewall, even if they can talk to each other but not ping.
Such as the command:
netsh firewall set icmpsetting 8 enable
-If the above does not work for ping. Turn off firewall, try ping, it should work. Turn firewall back on. Ping now works.
-Take away message: if a mdce service starts becoming confused. My solution here is to perform a complete reinstall.
