[ecco-support] Help in running ECCO

[Wang, Ou (US 329B)]

Hello Dimuthu,

It looks like the name list files: eedata, data, etc. are not founded by your run.

The name list files are downloaded by one of the “wget” the commands (page 3) in the V4r4 reproduction document:
wget -r --no-parent --user YOURUSERNAME --ask-password \
https://ecco.jpl.nasa.gov/drive/files/Version4/Release4/input_init

Make sure to make symbolic links in your run directory pointing to these name list files as done by
“ln -s ${inputdir}/input_init/NAMELIST/* .” in the example run script (page 5) in the reproduction document.

Best,
Ou Wang

Hello

I am trying to reproduce the ECCO simulation mentioned in  https://ecco-group.org/docs/v4r4_reproduction_howto.pdf<https://urldefense.us/v3/__https:/ecco-group.org/docs/v4r4_reproduction_howto.pdf__;!!PvBDto6Hs4WbVuu7!Jn5o50g6gtygnfJDmLNM6P0VOKnqQ-id6LDE7cIwdpkVMwJ-Lr9viKxTO45g-vhOdraYHZaxj3X1hpgr5hT2$>  on a non HPC environment. I managed to build the code and properly configure MPI and Fortran environment. When I tried to run the model using mpirun -np 96 ./mitgcmuv command, first I got an error mentioning that eedata file was not found. Then I created an eedata file with simple configurations as below

&EEPARMS
nTx=1,
nTy=1,
&

Next I got another error mentioning “(PID.TID 0000.0001) *** ERROR *** File data does not exist!”. I have noticed that MITGcm requires a data file which contains model parameters but there was no such in the NASA input repository. It would be a great help if someone can help me to figure out how to fix this issue. Am I missing something?

Thanks
Dimuthu
