I have been trying to run ERA5 data (single levels and pressure levels) for the past 2 weeks, but unsuccessful in real.exe for one physics suite but not for another.
Idont understand where i am wrong.


The error i encounter is as follows:

taskid: 0 hostname: login06.hpc.narl.gov.in
module_io_quilt_old.F 2931 T
Ntasks in X 1 , ntasks in Y 1

My rsl.error shows the following: Segmentation Fault:

This message is not helpful at all....

Is there any other error message? The error message may be saved in any of the rsl files, not necessarily in rsl.error.0000. We need the helpful message to determine what is wrong.

Nothing at all ... if I try running with eta levels specified, its not running, but if i don't specify the eta levels, then the real.exe is successful.

Please stay with the approach of not specifying eta levels. REAL can generate the levels in a reasonable way.
