What information you want to set up - a local scratch directory? I actually did not think of a starter_method, but I will give it a try. My problem probably is that I need to solve a level 10 problem with level 1 SGE knowledge. I want to achieve the following: I have defined a GPU resource as complex and each host provides two of these. SGE perfectly honours the resource requests, but I need to tell the user which of the GPUs has been assigned. This cannot be solved by creating a new complex for each GPU, because I cannot expect the user to choose the right one in the job script. Using your JSV idea and the prolog script, I almost solved the problem, but the last step is setting the environment variable containing the result - and that step is missing. > >> setup SGE's configuration to use ssh (in case you really need it), > >> all variables should be inherited from the sge_shepherd. > > > > You mean that any SSH session I open from the prolog should inherit the > environment?

Yes, I use ssh as rsh_command. Login via PKI is also working perfectly. Basically, SGE is working, I just have a problem with my prolog.
