I am trying to run cdo eoftime,4 input.nc of1.nc of2.nc but this process exceeds all wall time limitations. My input.nc file has around 36000 time steps and the domain is on 1.875 x 1.875 degree grid (40 x 30 grid points). The input.nc is 55 MB big.
Even with 150 h wall time limit and 400 GB of RAM the cdo eof was not able to finish. I had to abort it. What am I doing wrong? How does CDO scale? For a 1200 timesteps file and a domain of half of the size I run cdo within 2-3 minutes on my small workstation (4 GB RAM, 1 process, 5minutes) successfully.
