Re: [Condor-users] rsh error

[Becky Gietzel <bgietzel@xxxxxxxxxxx>]

Do you have the line (the comment is the explanation):

##  Path to the special version of rsh that's required to spawn MPI
##  jobs under Condor.  WARNING: This is not a replacement for rsh,
##  and does NOT work for interactive use.  Do not use it directly!
MPI_CONDOR_RSH_PATH = $(LIBEXEC)

in your condor_config file?


Thanks,

--Becky
