This announcement will go out to the linux-kernel mailing list on
Monday.  This is an OSDL pre-announcement.


OSDL is pleased to announce the kickoff of the foundational components
defined in the OSDL Cluster Architecture.  The foundational components
include a connectivity/communication service (TIPC), a membership 
service, and a publish/subscribe event service.

The connectivity/communication service (TIPC) and the membership 
service will be Linux kernel modules.  The proof of concept for the 
event service will be initially implemented as a user space deamon.  
Both the membership service and the event service are being developed 
to conform to the SAF-AIS specification.  Early releases of these 
services will be a subset of the full SAF-AIS interface 

These foundational cluster projects will not produce a full cluster 
implementation.  The intent is to enable the Linux OS as a 
"clusterable kernel".  With these foundational services enabled, 
when a kernel boots on a system on a network, the system would 
become part of the cluster.  The cluster is defined by locality on 
the network.  Applications and other cluster services (checkpointing,
resource managegers, etc.) would simply subscribe to membership events.
