2. 1. Exoplasim planet running code, Anaconda, python3.9, ubuntu, 2023
4. attempt to create exoplasim restart code
   1. you can continue running
   2. based on previous run.
5. 1. 11.12.2023 0000.0007
6. 1. in ubuntu you can install Anaconda, install to conda python 3.9
   2. here we use exoplasim 3.2.2
7. 1. pip3 install exoplasim[netCDF4]==3.2.2 (in Anaconda, python 3.9)

1. 1. convert to T21, input netcdf
   2. load one lon, lat, z grid
   3. or Tarasov glac1d grid
3. 1. MPI NOTE: if you use more than
4. 1. one processor, you cannot in most cases run MPI in root
   2. you can use even number of process in mpi: 2, 4, 6 ..
