i have setup a little cluster for parallel computation with open suse 12.1 with 4 nodes. I want to find a software which can manage all these nodes in a gui way, like network neighborhood in windows7.
could you please give me some advices.
Regards

Are you willing to shell out money? There are various software products like Bright, Platform, or Moab that have been traditionally been big players in the cluster space. I've not seen any particularly good open source GUI management tools, but there are plenty of good open source command line tools for managing clusters.

Your requirements aren't all that clear to me, either. what do you mean by "manage all these nodes in a gui way"? What do you want to manage? User accounts? Network settings? What? I am not a Windows guy, but I didn't think that Network Neighborhood had much in the way of management functionality; it just showed you what network resources (shared pritners, disks, etc.) were available on your local LAN.

and "parallel computation" and "clustering" are not necessarily the same thing.
What was your intended goal for this cluster?

Dear friends, I use it for high performance computation with mpich.

Dear friends:
thank you very much for you feedback. " manage all these nodes in a gui way" means i can performe various operations only in the server node. i can log into the other three nodes in the manage tool. and can transfer various files between them.
