Run CAM5.0 with debug in configuration

[weili@psu_edu]

Hi Everyone,

I am trying to run cam5.0 on a Linux x86_64 with pgi-10.6 and mvapich2-1.5.1. Something confusing me is: I have to set -debug in configuration to get model run, like this: $cfgdir/configure -dyn fv -hgrid 1.9x2.5 -ocn docn -nosmp -ntask 4 -debug . Otherwise I will encounter the failed run with such kind of error message:
rank 2 in job 3 mc1031.met.psu.edu_45884 caused collective abort of all ranks
exit status of rank 2: killed by signal 9.

Is there anyone once encountered similar problem?

Thanks very much!

The fact that you get the model to run in debug mode, but not when debug is off is a classic sign of a compiler generating bad optimized code. So I think it is very possible that this is a pgi-10.x problem. We have been experiencing problems with high resolution runs (1/4 deg cam) on cray platforms using the latest pgi-10 compilers. I haven't gotten a chance to verify whether this problem exists for lower resolution runs or not (and won't have a chance until at least next week). We are currently doing production simulations with CESM1 on cray platforms by backing off to the pgi-9 compiler. It that's an option for you then I think it would be worth trying.

Hi eaton,

Thanks so much for response. I will try a pgi9 compiling and see whether the problem will be fixed.

Thanks!

Hi eaton,

The problem was fixed when I compiled CAM5.0 with pgi9.0-4.

Thanks very much for help.
