Re: running ice code ...

Do you know if any of the ice observed there was formed there, or was it all advected southward from outside your domain? I do not have data to determine which source is more important, but I know sea ice is constantly advected from the north. I did not have the boundary condition, because I don't ...

Re: running ice code ...

Hi Ufuk,
Have you tried to increase heat loss at the surface of your domain, just to reduce the temperature, and see whether ice can form?

Re: running ice code ...

Hi Kate, My area of interest is the Labrador Sea. I attached a figure to be more accurate. I have four open boundaries. I am not sure whether the vertical boundary heat loss or the southward and eastward cold and fresh water (or ice) transport is more important. However, the ice in this region often...

Re: running ice code ...

Hi Ufuk, I have been using Kate's sea ice code too, and did not get any ice except in a very thin boundary layer. I am wondering if you have successfully produced ice reasonably distributed, and how did you do it? I used gradient boundary condition for the sea ice, because I do not have sea ice thic...

Re: openmpi problem

Hi, I just found out the problem is actually hardware related somehow.
I cannot use all the two threads of each core to run the model, I can only employ 10 cores at the most.

Thanks, Kate!

Re: openmpi problem

Hi Kate,
Thank you for your reply. I also tried without the '<', but the result is just the same.

I don't know about runmpi, I do which runmpi, nothing returned.

Re: openmpi problem

Hi Kate, The mpi related libraries are located in the /usr/lib directory as I specified. And I did use mpif90 to compile and link "successfully" without errors. However when I use 'mpirun -np 20 ./oceanM < ocean.in', the following errors occur: mca: base: component_find: unable to open /usr/lib/open...

openmpi problem

Hi all, I am using mac os x 10.6.8 (x86_64), and have gfortran as fortran compiler. I downloaded openmpi and installed it. When I try to compile ROMS with MPI, I got the error message as follows: ======================================================================== /usr/local/gfortran/bin/gfortra...
