Wrong choice of grid 01 partition or number of parallel nodes

#1 Unread post by remit »

Greetings,

Initially, I thought the ROMS in COAWST needed an update to version 3.8, but I'm still encountering an error:

Code: Select all

Resolution, Grid 01: 222x184x10, Parallel Nodes: 1, Tiling: 3x1

ROMS/TOMS: Wrong choice of grid 01 partition or number of parallel nodes.
NtileI * NtileJ = 3
must be equal to the number of parallel processes = 1
Change -np value in mpirun or
change the domain partition in the input script.
Found Error: 06 Line: 214 Source: ROMS/Utility/inp_par.F
Found Error: 06 Line: 134 Source: ROMS/Drivers/nl_roms.h, ROMS_initializ
I'm running the model (on laptop) with mpirun -np 3 ./coawstM input_roms_forecast4.in > out.log, and I've already made sure that NtileI = 1 and Ntilej = 3.
Any help from anyone would be greatly appreciated. Thanks.

edit:
I've also changed the number of parallel nodes to 1, and have got a problem:

Code: Select all

Process Information:

 Node #    0 (pid=   19923) is active.

 INITIAL: Configuring and initializing forward nonlinear model ...
