prompted for unknown password

Some ssh setup problem?

antonst commented 8 years ago

how did I manage to run previous examples on Stampede then?

antonst commented 8 years ago

The only difference is that instead of xsede.stampede I have used stampede.tacc.utexas.edu as suggested in documentation.

andre-merzky commented 8 years ago

Hmm, I am not sure how that setting differs on the RP layer. Vivek?

vivek-bala commented 8 years ago

in config.json we have xsede.stampede key which picks 'gsissh'. That's why this is popping up.

vivek-bala commented 8 years ago

I think the docs might be using stampede.tacc.utexas.edu. let me fix that in RTD.

vivek-bala commented 8 years ago

Fixed RTD with "xsede.stampede".
