[Bigjob-users] Problems with BigJob example

[Andre Luckow]

Hi Ole,
BigJob doesn't use SAGA for launching jobs - the default job adaptor
has severe limitations, e.g. it cannot launch MPI jobs or jobs on
remote machines. The primary use case of BJ is the management of
multiple nodes. For this purpose, BJ relies on SSH. Since the local
version is just used for development purposes the same mechanisms are
applied here.

Best,
Andre
