model failed in executable

Description

Hi,

I have a LAM run at 4km resolution over part of Antarctica which has failed with the error 'failed in model executable'. I've looked at the .leave file and can't find any explanation for why it failed. The job is a copy of the '4km run' over the UK.

I did include a modification'VN7.1_increased_amaxsize' which increased the maimum possible row and column size to 2000. This was my first time using FCM, but I think I done it correctly.

The job id is xfbsf.

Thanks,

Andrew

Hi Andrew,

In your .leave file you will see

[NID 00990] 2010-07-29 17:15:15 Apid 2105026: OOM killer terminated this process.

OOM stands for "Out of memory". It looks like your increase in amaxsize has work, but you probably need to increase the number of processors proportionately. You are now using 8x8. Perhaps you could try 32 NS procs x 8 EW procs?

Regards,

Willie
