Which variable do you want to set? Did you try -V on Kraken? If it works, then let's use it. Modifying the submit script or run script would also work; no need to provide a generic solution if there's only a single use case.

Hello all,
I'd like to use PBS's -V switch (propagates environment settings to the qsub script) on Kraken (through simfactory2). Simfactory currently does not use this swich on Kraken. In fact NICS recommends against using -V (http://www.nics.tennessee.edu/computing-resources/kraken/running-jobs#Batch%...): --8<-- Note: Please do not use the PBS -V option. This can propagate large numbers of environment variable settings from the submitting shell into a job which may cause problems for the batch environment. Instead of using PBS -V, please pass only necessary environment variables using -v <comma_separated_list_of_ needed_envars>. You can also include module load statements in the job script. --8<-- TACC on the other hand actually requires you to have the flag present (for the modules I presume). Did anyone every actually experience any issues with -V on Kraken?
Mostly I would like to use the flag so that Cactus' $ENV{'...'} mechanism works without me having to modify the run/submission scripts by hand. Is there maybe a simfactory option to define extra environment variables (I only need one but would rather not hard-code it into the submission script and instead could add it to the submit call)?
Yours, Roland
