Comment (by Michal Pirog):

The complete set of ID contains three files:

1. BNSdata_properties.txt - sgrid configuration summary
2. checkpoint.0 - main file with ID
3. sgrid_id.par - sgrid parfile

All of them are required to be there. The only thing you need for Cactus to run (of for the test) is a path to the directory where all there are located. It is one line you mentioned before:

DNSdata::sgrid_datadir           = "../../../arrangements/CactusSgrid/DNSdata/test/sgrid_id"

The file

"../../../arrangements/CactusSgrid/DNSdata/test/sgrid_id/sgrid_id.par"

is not Cactus parfile. It is sgrid parfile and simply must be there.
