MPICH problem

Reported by: till Owned by: willie
Component: UM Model Keywords: HiGEM, processor count
Cc: Platform: ARCHER
UM Version: 6.1


Hi there,

I'm trying to run HiGEM on Archer. It's not quite working yet, the run stops and the .leave file says:
Attempting to use an MPI routine before initializing MPICH


Could you please check?

Hi Till,

Could you give me read access to the leave file please

 cd ~
  chmod -R g+rX .

If you could do the same on your /work directory, it may save time later.

  • Keywords HiGEM, processor count added

Hi Till,

You're getting

Error : MAXPROC is not big enough.
 You will need to edit the parameter in comdeck PARPARM.
 MAXPROC=  288  nproc_max=  384

Remember that on ARCHER you should use a multiple of 24 processors. So change 24x16 to 12 x 24 and you won't have to edit the comdeck.
