Hi Christoph,

It could be that Eclipse is getting overwhelmed. For BG we use a hierarchy to avoid trying to display too many objects at once, so it should be possible to set up a default layout for SuperMUC also. Can someone from Juelich help Christoph with this?

Thanks,

Greg

Greg,

 

I guess, you meant the .eclipsesettings on the remote $HOME ?

 

I did the change as follows.

di69job@login03:~/.eclipsesettings/rms/LL> pwd

/home/hpc/pr63vu/di69job/.eclipsesettings/rms/LL

di69job@login03:~/.eclipsesettings/rms/LL> grep open da_nodes_info_LML.pl

open(IN," $cmd -L machine -l |");

open(OUT,"> $filename") || die "cannot open file $filename";

 

Then I restarted eclipse, opened the monitoring view, and switched on monitoring for remote connection "SuperMUC".

 

This caused my eclipse to hang. The eclipse screen froze, the process eclipse took more CPU load than a single core (typically CPU1 100%, CPU2 38%). I had to kill eclipse (signal terminate), which put the CPU-load back to normal and made the fan of my TP go quiet again.

 

Could it be that the perl script is overwhelmed by the number of machines ?

 

I executed the following command to test on the amount of output lines to be scanned by perl.

di69job@login03:~/.eclipsesettings/rms/LL> /usr/bin/llstatus -L machine -l \

| wc

706948 2451395 23667162

 

Could that pose a problem ?

 

At least the llstatus command returns OK on the command line.
