Error in ntasks-per-node

Unified Model

Hello.

I’m having the following error in several suites. Any clues?

srun: Warning: can’t honor --ntasks-per-node set to 40 which doesn’t match the requested tasks 384 with the number of requested nodes 10. Ignoring --ntasks-per-node.

Suites with this error:

u-bo026-n512-ens0-r2
u-bo026-n512-ens0-r3
u-bo026-n512-ens3
u-bo026-n512-ens3-r1
u-bo026-n512-ens3-r2
u-bo026-n512-ens3-orig
u-bo026-n512-ens6-orig

I changed MAIN_ATM_PPN to 40, but other suites with the same configuration ran without this problem. Examples: u-bo026-n512-t7 and variations.

Kind regards, Luciana.

Hi Luciana,

This is a warning and is not the cause of the runs falling over. u-bo026-n512-t7 had the same warning.

u-bo026-n512-ens3-r1 has fallen over due to being unable to read a NetCDF file. (See further down the job.err file.)

Regards,
Ros.
