[Wien] I still have problem with wienk in parallel mode

[Laurence Marks]

Sorry, no. The error report you are getting implies a communication error
and ping wont fully check this. Run the ssh command at the end of your
output just at the terminal, with the appropriate exec. It is either this,
or somehow you are losing the sed replacement of the executable name.
