Subject: [ccsm-scientists] [ccsm-progs] update on bluevista compilers -
	UPDATE

CCSM Software Engineers are continuing to work closely with the folks
in CISL to resolve the problems associated with the recent upgrade to the
xlf 11.1 compilers on Bluevista. 

The reported problems to date include:
1.  Segmentation fault when CAM tries to write an initial file.   This 
happens
in non-debug mode only.  Turning off initial file writes will side-step 
this
problem (ie setting namelist variable inithist='NONE').

2.  Segmentation fault in DOM or SOM.  This happens when running CAM
in non-debug mode *and* mpi-only (which is currently the default for CCSM4)

3.  Run-time failure in the radiation code when running the 1870_control
configuration with trop_mozart_ghg_paero chemistry.  This only happens in
debug mode.

Problems 1 and 2 have code work-arounds that will be committed to the CAM
development trunk in an upcoming tag.  They have also been summarized in
reports to the folks at IBM for analysis.  Problem 3 is still under 
investigation.

If you encounter any of these problems, you are advised to try running 
on Blueice,
where older versions of the compilers are used, or utilize a copy of the 
older
compilers that CISL has installed under /contrib on Bluevista.  This was 
explained
in our original announcement, attached below.

And if you encounter any other sort of problem that you believe may be 
related
to the compiler upgrade, please pass that information along to us in CSEG.

We apologize for any inconvenience and we will keep you informed of any
progress on these matters.

Message-ID: <48359EDD.3090600@ucar.edu>

Good Morning,

There will be a CCSM Scientist meeting today at 2:00 p.m. in the Damon 
Room.  To join in via teleconferencing call 1-866-740-1260 and use 
passcode 7907.

PLEASE NOTE:  This is a new phone number and passcode.  NCAR has 
switched providers for our teleconferencing, and the old numbers will no
