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.
