The -V option is removed by PR https://github.com/ESMCI/ccs_config_cesm/pull/97 because the NGPUS env variable is not set properly on Derecho's compute node and the GPU run will crash accordingly. This issue can be resolved later on Derecho and this PR will add -V option back for PBS system to avoid the error above.
