[cam-users] Anybody have CAM running on an Opteron?

[Tim Carlson]

First of all I have less than an hour of experience with CAM ;)

We have an Opteron running UnitedLinux (aka SUSE). I have installed the
5.0 Beta Portland compilers. Using gcc and pgf90, I installed
netcdf-3.5.1-beta10. I configured and built CAM using the
cam2.0.2_source.tar.gz source code I downloaded on Monday. I just
configured the serial version and took the defaults everywhere except
where I specified I wanted to use pgf90 and pgcc.

Surprisingly (to me) CAM built with only a few warnings. I then generated
a namelist and tried to run CAM. Things start off well enough, but I get
an error when loading a particular file. Here is the truncated output

========================================================================
./cam < namelist

So I get a segfault. If I run cam inside of gdb and do a backtrace, I get
this information

Program received signal SIGSEGV, Segmentation fault.

If I redo the configuration and enable debugging

Enable compiler debugging options? [n]: y

the code fails to compile and I get this error

If anyone would like more information, just let me know. Am I barking up
the wrong tree? Maybe I should be looking for problems netcdf instead?

Thanks!
