Error in reconfiguration : The program was unable to request more memory space

Reported by: rm024650 Owned by: annette
Component: UM Reconfiguration Keywords: ancillary file
Cc: Platform: ARCHER
UM Version: 8.5


Dear CMS helpdesk

I am trying to run a copy of the standard N96 GA6 job with a modified orography ancil (job id xmkxc). The job failed at reconfiguration with the error message in /home/n02/n02/rm024650/output/xmkxc000.xmkxc.d16092.t180656.rcf.leave :

tcmalloc: large alloc 1651075284992 bytes == (nil)
lib-4205 : UNRECOVERABLE library error
The program was unable to request more memory space.

I'm not sure why this is happening. In a separate run (xmkxb) with a different modified orog ancil everything worked fine. Any advice please?

Hi Mike,

The orography file that you have specified for this job is in NetCDF format which the UM can't read, but it tries to anyway creating a memory failure. In xmkxb where the recon has worked, the file is in the proper UM ancillary format.
