Hi, Dear all 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?

Nope. You need to have the Globus header and libraries installed in order to build the SAGA preWS GRAM adaptor. Have a look at the installation manual in the docs directory.

...

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?

You need GT in advance ;-)

...

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?

We currently have job service adaptors for

* Globus preWS GRAM * OMII GridSAM * Condor * Platform LSF (will be part of SAGA 1.1 - to be released in a couple of days)

I don't know if it is possible to build a self contained GRAM package. I guess so - I mean you could just build the GRAM client libraries and, let's say grid-proxy-init. Ask the Globus guys how this works ;-)

...

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.

Well, actually we use C++ in all our examples. The API wrappers we currently have for our C++ reference implementation are Python (working) and C (not yet working).

I don't know about the status of the SAGA Java implementation. Maybe one of the Java guys on this list might be able to help?!

...

Best Regards ye

Hope that helps.

Cheers, Ole
