how to use servergroup?

Hi all,

I have seen how to create a servergroup in Tx RZ12 joining servers into a group and leaving free Workprocesses (for other users).

Now I want to execute a program in parallel using this server group and I do not know how.

(How) Can I use a servergroup executing a standard program? and/or using a self;written program?

I would appreciate if someone could geive me examples/explanation.

Thanks in advance

Thomas
