Hello, I am looking for library, tool or something else for this: I have virtual servers and upon them virtual cluster with scheduler which chooses servers to add to the virtual cluster dedicated to some job. Servers are geographicaly wide spread in nodes. There is no problem with gaining information about server recources and status in local nodes (e.g. with ganglia) but there are problems with exchanging information between nodes (network overloads, etc.). My idea is to build a database which will keep information about local status of servers. This database will be send to all nodes. Each node will have the complete grid status. The database will be marked as valid when more than half of all nodes publish its status. If the status is not set as valid the node will wait for new valid information. Do you know anything like this or do you have some experience? Thank you, Jarda
