Hello all,
DATADIR (better: INPUTDIR, because it's shared between simulations, and simulations shouldn't really write there) would be set in the mdb. A future feature could be to copy data from INPUTDIR to the simulation's directory, if desired. INPUTDIR should be defined in the MDB.
NICS seems to have updated their system since I last used it. Now one receives:
---8<--- Warning: Your job requests that all of your current shell environment settings (19410 bytes) be exported to it. This is not recommended, as it may cause problems for the batch environment in some cases. You are strongly encouraged to export individual environment variables with the -v variable_list directive instead; see the qsub man page for details
Please contact help@xsede.org if you need assistance. ---8<---
So I would say that the "-V" option is definitely out.
Yours, Roland
