<<  linux cluster success stories?, http://bb.cgd.ucar.edu//viewtopic.php?t=40 >>

Message: Even though the model still does not run in the linux cluster here at Yale, I am still clinging to some small bit of hope that it will be able to run once I fix some small error that I have overlooked thus far.  Right now it appears that CAM3.0 does not like the MPICH that is currently installed, which is version 1.2.6.
<br />
<br />I am asking that, anybody who has successfully been able to run CAM3.0 on a linux cluster, could you please email me and tell me what version of MPICH you are using?
<br />
<br />Thanks,
<br />Cathy

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

Message: Cathy,

<br />I don't know what the difference is between the T and W symbols (I read the
<br />nm manpage and didn't understand it), but I also get the W version on a
<br />linux system where cam3 runs in spmd mode.  So I don't think that's a
<br />problem.
<br />
<br />When configure is run interactively (-i option) then its default behavior
<br />is to run a test to check that the mpi library can be linked to.  Without
<br />the -i option that test is not run unless you give configure the -test
<br />option.  So issuing the command "configure -spmd -test" will give you the
<br />same result that you got interactively by accepting all defaults except to
<br />turn spmd on.
<br />
<br />When you run "configure -spmd" from the commandline and it is successful,
<br />it has checked to make sure that mpif.h and libmpich.a exist in the
<br />directories you've specified (or the default locations), but it has not run
<br />a test to confirm that libmpich.a can be !
linked to.  In that case the
<br />failure is occurring when you type gmake and the command is issued
<br />to build the cam executable.
<br />
<br />It appears that there is still a problem with your mpich installation.
<br />Here is the program that configure tries to build to test that you can link
<br />to the mpi library:
<br />
<br />      program test_mpi
<br />      implicit none
<br />#include &lt;mpif.h&gt;
<br />      integer :: ierr
<br />      call mpi_init(ierr)
<br />      end program test_mpi
<br />
<br />This test needs to work before it will be possible to build cam.

Message: Cathy,
<br />
<br />I see that the cam3.0 code still contains the capability to add TAUVIS to the output history files,
<br />however the field will contain zeros since it is never actually set or used in the code.  It is a bug 
<br />to allow adding TAUVIS to the history files.  We'll get that fixed.
