Each DAS cluster consists of a file/compile server and a number of worker
nodes. The file/compile server is called dasXfs (X is
0, 1, 2 or 3, according to the cluster base), the worker nodes are named
The DAS must be used in the following way:
program development (editing, compiling) is done on the
Program execution MUST be done on the worker nodes,
NEVER on a file/compile server. The file/compile servers
are usually heavily loaded just carrying out the tasks they are
User programs that run on a file/compile server harm all other
users of that DAS cluster!
This rule also holds for sequential runs of parallel
Running of jobs on the worker nodes MUST be done via the
tool prun, which offers
sufficient abstraction and flexibility for nearly all needs.
Users who do not obey these usage rules risk blocking of their account!
