segmentation fault when running HadCEM

Reported by: ggjhtw Owned by: um_support
Component: UM Model Keywords: segmentation fault, HadCEM
Cc: Platform: Other
UM Version: 4.5


Hi there

I am trying to run HadCEM, the high res ocean coupled GCM at Bristol. I can compile successfully but my run is refusing to compile, it falls over at timestep 1 with a seg fault. I have attached the lates output (.leave) file. I am using a local compile override to increase the buffer size as recommended here

As far as I can tell there is no useful information in the output file I have attached and so I would be very grateful to hear of any tips you may have. I have already tried increasing the number of processors used but this does not fix the issue.

Many thanks

Jonny Williams

We are struggling to provide any help - have you been in contact with Gethin, he is better placed to assist you with a problem ob the Bristol machine.

Thanks for your message

I have been in touch with Gethin and he has suggested running with the "-g" and "-traceback" compiler flags but this still has not brought up any more useful information. I will be seeing Gethin about this next week so hopefully things will start to make sense soon.

Hi Jonny,

I'm assuming you got help from Gethin so I'm closing this ticket.
