The original file did not have enough data to complete 2005-12. The new file contains
the additional date 20070701 with data duplicated from the 20060701 time point.

Comments

 
1. Erik Kluzek's mods in

/fis01/cgd/home/erik/ccsm4_0_beta35_fixrest/scripts/testrest/SourceMods/src.clm

were included in a new build done on 2009-12-02 22:55.  There are two files:

-rw-r--r--    1 erik     ncar          42931 Nov 30 14:27 driver.F90
-rw-r--r--    1 erik     ncar          27473 Nov 30 14:29 restFileMod.F90

which fix incorrect behavior causing the rpointer.lnd file to have an .i.
file written into it under certain circumstances.  [See bug 1079]


2. Beginning with 1906-01-01 we ran with the following added MPI env vars:

      # MPI Environment to debug communication timeout
      setenv MP_EUIDEVELOP                yes
      setenv LAPI_DEBUG_COMM_TIMEOUT      pause
      setenv LAPI_DEBUG_TIMEOUT_SECONDS   120
      setenv MP_EAGER_LIMIT               0

This causes the model to run without crashing on "COMM TIMEOUT ERROR"s. Setting
the MP_EAGER_LIMIT to zero causes the overall model throughput to drop from
12.7 SYPD to 11.6 SYPD.


3. In Buildconf/cam.buildnml.csh at line 55 I made the following change:
