[Wrf-users] parallel real.exe processes attempting to open namelist.input

[Zulauf, Michael]

Previously I wrote:

Ø  Next I tried modifying my job script so that it created work directories on the local disk of the non-I/O nodes. 

Ø  In this way there is a work directory with the same name on all nodes, local to all nodes.

 

Which led to the failure from trying to open namelist.input.  To extend this experiment, I tried placing a copy of namelist.input in the local work directories, on each node.  This allowed both real.exe and wrf.exe to run, apparently correctly from that point on.

 

So this may be a work-around for my problem, but I still see this as an unexpected issue, which I didn't have before.  It doesn't seem correct that all the non-I/O processes should be opening namelist.input.  Has anyone else seen anything like this?  Any suggestions for other/better fixes?

 

Thanks,

Mike
