Hello,
I'm running CESM v2.1.5 with B1850 compset. The run keeps hanging near the end of the initialization irrespective of number of nodes. None of the log files show an error message. I have come across similar issues in the forum but none help. I am using intel compiler v 2023.1.0, with impi as my mpi lib and pbs job submission. I have used upto 9 nodes, with max task per node =128 (it is our institute system). As suggested by other discussions I have put export OMP_STACKSIZE=256M, ulimit -c unlimited etc. the pe layout is the default one :
./pelayout
Comp NTASKS NTHRDS ROOTPE
CPL : 1024/ 1; 0
ATM : 1024/ 1; 0
LND : 512/ 1; 0
ICE : 512/ 1; 512
OCN : 128/ 1; 1024
ROF : 512/ 1; 0
GLC : 1024/ 1; 0
WAV : 256/ 1; 0
ESP : 1/ 1; 0
Kindly help. I have attached my run log and machine files (machine name is champ).
