<<  issues linking to the MPI library, http://bb.cgd.ucar.edu//viewtopic.php?t=30 >>

Message: If I issue the following command,
<br />
<br />[ccm33 at bulldoga ccm33]$ cam1/models/atm/cam/bld/configure -spmd
<br />
<br />I get this output:
<br />
<br />creating /home/ccm33/Filepath
<br />creating /home/ccm33/params.h
<br />creating /home/ccm33/misc.h
<br />creating /home/ccm33/preproc.h
<br />creating /home/ccm33/Makefile
<br />creating /home/ccm33/config_cache.xml
<br />configure done.

<br />
<br />This seems to work fine.  The netcdf and mpi include and lib directories are specified in my Makefile correctly.   However after running configure this way, I then run gmake (after doing make clean) and get the huge list of errors like:
<br />
<br />
<br />-----------------------------------------------------------------------------------------
<br />test_mpi.o(.text+0x10): In function `MAIN_':
<br />: multiple definition of `MAIN_'
<br />cam.o(.text+0x10): first defined he!
re
<br />/usr/bin/ld: Warning: size of symbol `MAIN_' changed from 5339 to 49 in test_mpi.o
<br />STATICEcosysDynMod.o(.text+0x3a62): In function `staticecosysdynmod_readmonthlyvegetation_':
<br />: undefined reference to `mpi_bcast_'
<br />STATICEcosysDynMod.o(.text+0x3ac5): In function `staticecosysdynmod_readmonthlyvegetation_':
<br />: undefined reference to `mpi_bcast_'
<br />STATICEcosysDynMod.o(.text+0x3b28): In function `staticecosysdynmod_readmonthlyvegetation_':
<br />: undefined reference to `mpi_bcast_'
<br />STATICEcosysDynMod.o(.text+0x3b8b): In function `staticecosysdynmod_readmonthlyvegetation_':
<br />: undefined reference to `mpi_bcast_'
<br />---------------------------------------------------------------------------------
<br />
<br />However if I configure interactively, setting spmd on this way, I get the error output shown in a previous email above when the test of the MPI library failed.  I am not sure why configure works when it is not run interactiv!
ely.  
<br />
<br />Either way, the MPI library is not linkin!
 g correc
tly, even though it is specified correctly.

<<  radiation calculation, http://bb.cgd.ucar.edu//viewtopic.php?t=31 >>

Postercathryn.meyer at yale.eduPostedMon Oct 18, 2004 2:05 pm MDT, http://bb.cgd.ucar.edu//viewtopic.php?p=85#85
Message: I am running CAM3.0 in aquaplanet mode with revised SSTs to get rid of the Hadley circulation.  In order to make this work correctly, I need to compute radiation as though there are no clouds in the atmosphere.  I am thinking of changing the minimum cloud amount to distinguish from clear sky OR the cloud fraction that are used in the model physics code RADCSWMX.  Would this be a good way to proceed with this?  Is there any single variable that is read into this code (if this is the correct code to use) that I could just turn off so the code does not see any clouds when it computes radiation?  I do not want to turn off clouds in the model though, I just do not want the radiation code to see them.
<br />
<br />If this is a more daunting task than I realize, would it be easier to read in a climatological radiation from a file and to turn off interactive (model calculated) radiation completely?
<br />
<br />Thanks,
<br />Cathy
