[cam-users] SPMD/MPI issues

[Cathryn Meyer]

Hello,

I am trying to run CAM3.0 on a linux cluster using two nodes, and the
model configured and compiled fine, however now every time I try to run
it I get the error message 

Visible optical depth (tauback) =     0.000000000000000
(shr_orb_print) Orbital parameters calculated for year: AD      1950
  ------------------------------------------
 ISCCP calcs and history IO will NOT be done
 Problem factors: 2**            6  * 3**            0  * 5**            0
 SPMDINIT_DYN: nprocs(            1 ) must be a multiple of 2
 ENDRUN: called without a message string
[0] MPI Abort by user Aborting program !
[0] Aborting program!
p0_25511:  p4_error: : 1


No matter what I change in my PBS submission script (no matter how I
change the number of nodes or processors).  Any ideas?

Thanks,
Cathy
