Hi,<br>
<br>
I mentioned this to Todd and he suggested I post my user experience
to the developer team.<br>
<br>
I've been running cam-mpas, and revision 983 brought up a small
run-time hassle. Is there any way to automatically put a unique name
on mpas output files instead of generic names like "output.nc",
"ocean.nc" without editing namelist.input every time? For example,
they could be time stamped by model time (YYYY-MM-DD-HH as in CESM)
or number of time steps) or the real-world time at which the job is
running.<br>
<br>
It's not a big deal during testing, but in production runs it starts
to be a hassle. I have set my run script to capture the date from
the latest CAM restart file and sed that into namelist.input so that
the output files have a unique and meaningful name. It works fine
but errors can still happen. In production runs, with one misnamed
file, or writing over an output file, things get messy fast. <br>
<br>
thanks<br>
cheers<br>
