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

Message: I am trying to compile CAM3.0 (patched version) on a linux cluster, however the MPI library is not linking properly.  When I attempt to compile the model, I get the following error messages (I get more than what I have pasted below, I cut most of them out to save space):

Message: We'll need more information to help:
<br />What version of mpi are you using?
<br />What compilers (c and fortran, exact versions) are you using?
<br />What configure command did you issue to configure the model?
<br />
<br />If you've modified the configure script or your Makefile, please describe those changes as well.

<<  initial condition files, http://bb.cgd.ucar.edu//viewtopic.php?t=29 >>

Message: First of all, the sst dataset you require is distributed with the model.  The file atm/cam2/sst/sst_HadOIBl_bc_64x128_1949_2001_c020411.nc contains SSTs from 1949 through 2001.
<br />
<br />The easiest way to obtain the initial conditions you need is to have the model generate them itself.  You'll need to build a namelist containing the following entries (along with the standard entries):
<br />START_YMD = '19960901'
<br />NELAPSE = -123
<br />SSTCYC = .FALSE.
<br />BNDTVS='&lt;path_to_sst_files&gt;/sst_HadOIBl_bc_64x128_1949_2001_c020411.nc'
<br />
<br />This will start the model integrating on Sep 1, 1996.  When it reaches Jan 1, 1997, it will by default write out a set of initial conditions for the land and atmosphere.  You may use these for subsequent experiments.
<br />
