Re: [ptp-user] parallel application run failure

The only errors I can think of that should have been reported and did not 
get reported in your case would be any messages issued by Parallel 
Environment, where those messages have the string 'ERROR: 0031-' in them. 
When the proxy is working correctly, those messages should be showing up 
in the Eclipse console window, in red. I think those messages were getting 
lost because of the host name conflict between the host list file and the 
name known by PE. Since the proxy could not match up names, it had nowhere 
to send the output.

The error messages in the trace highlighting the different node name were 
a side-effect of that mismatch. Normally, none of those messages would 
have been generated.

I think I have a solution which will prevent this hostname mismatch 
problem from happening. I need to give it a little more thought then code 
a fix and test it.

Thanks Dave. The bug id is 
https://bugs.eclipse.org/bugs/show_bug.cgi?id=286575

I think generating more error reporting would be a very useful step as 
well. I saw some useful errors emitted in the trace output. Can you 
elevate those into the error log in the gui?
