Hi, Dear all: Since it seems nobody is using sgag-user mail list, I have to bore the server and post my question here again. I am pretty new to SAGA. Due the installation manuel of SAGA, it seems SAGA manage jobs' behavior via GT GRAM. In this case, I have several "green" questions: 1. Do I need to install a complete GT in advance? I mean, is the installation of GT is mandatory? It seems SAGA installation package contains a pre-gram subdirectory, is it everything i need? 2. If I don't need GT in advance, how could i submit job to remote machines(even in the same cluster)? Using "grid-proxy-init" seems acquire additional GT package? 3. I feel SAGA focuses to GT/OMII currently. I wanna know, besides the aforementioned two middleware, is there other option? For example, if I only have a "pure" Condor or PBS system (without GT), could I use SAGA to submit job to the RMSs directly, or with only help of self- contained GRAM package, instead of a complete GT system? 4. I noticed there are two language binding(C/Java) announced. However, almost all the presentations are given with example of C binding. I wanna whether Java binding is able to provide the same support. Best Regards ye
