Porting CLM5/CIME to LSF based cluster


Code:
Hello everyone,

We're currently experiencing the following issue when trying to port CLM5 to our linux cluster running the LSF batch system at the University of Göttingen:<br /><br />Going through the "Steps for porting" [1, section 6.3] for CIME we created the required files in $HOME/.cime according to the XML schema definitions [2] but running scripts_regression_test.py fails.

Our first question is whether the reggression tests are up-to-date and expected to run successfully. Otherwise, does it makes sense to run the software without having a successfull regression test run? The test fails with the following message (at the very end of TestStatus.log)

ERROR: Unable to determine the correct command for batch submission.<br />
We're running Python 2.7.5 with pylint installed using pip in a virtual environment. Our CIME installation is at git tag clm4518/n04/cime5.4.0-alpha.03

We also attached the env_batch.xml file that's being created by the regression test, since we suspect the error occurs when it gets evaluated. The file contains the LSF configuration included in CIME [3] and the configuration for our LSF setup (see attachment config_batch.xml).

Any insight on this issue you share is greatly appreciated.

Best regards
Christian, Ashehad and Fernando
