CHECKDEFS - cannot activate option: TS_MPDATA

[kee]

Hi,

I tried to run the LATTE case, and it's Ok during the compiling, but broke during running.
Some information is as the following:
_______________

CHECKDEFS - cannot activate option: TS_MPDATA
in serial with partitions or shared-memory...
Use distributed-memory (MPI) in parallel runs.

Elapsed CPU time (seconds):


ROMS/TOMS - Output NetCDF summary for Grid 01:

ROMS/TOMS - Configuration error ..... exit_flag: 5


ERROR: Illegal model configuration.
________________________________________

can anyone give some ideas?

Hi Kee,

try to compile your code by enabling the MPI
option on the build.bash/build.sh script, specifically
uncomment USE_MPI and USE_MPIF90 commands. Now if your
machine have, for example, the mpich2 library after your
compile is finished type this

Code: Select all

echo MPD_SECRETWORD=roms > ~/.mpd.conf
chmod 600 ~/.mpd.conf
mpd &

and finally to run the application

Code: Select all

mpirun -n k ./oceanM ./<ROMS-folder>/<your input file>.in

where k is the number of tiles you have.

Hi ymamoutos,

I did what you said, and ran the script with

Code: Select all

mpirun -np 16 ./oceanM ocean_lattec.in > run.log

but it came out other errors. I pasted the infomation within run.log below:

 ERROR: Illegal domain partition.

BTW, I compiled the build.bash with 16 nodes, and the NtileI * NtileJ was set 4*4 in ocean_lattec.in file.

what's wrong with it?
how can I mpirun successfully?

Thank you!

mpirun -np 16 ./oceanM ocean_lattec.in > run.log

You told mpirun to use 16 processes, yet ROMS thinks it only has one. This is a problem with your MPI setup. Do you have a system manager to ask? I would try to get some kind of simple "hello world" MPI program running before working on ROMS. Perhaps MPI comes with some test codes you can try.
