Hybrid Cluster: A Mixed Windows/Linux Cluster Solution
We are happy to announce the release of the Moab Hybrid Windows/Linux Cluster solution, which uses Moab Cluster Suite to dynamically change a node's OS on the fly in order to meet workload needs. As a meta-scheduler, it optimally determines when the OS mix should be modified based upon defined policies and service level agreements as well as current and projected workload. When the specified conditions are met, triggers the OS change using a site's preferred OS-modification technology, such as dual boot, diskfull and/or diskless provisioning or virtualization (i.e., via Hyper-V within Windows Server 2008, VMware, or Xen).

Did You Know: Server High Availability
The option of running TORQUE in a redundant or high availability mode has been implemented. This means that there can be multiple instances of the server running and waiting to take over processing in the event that the server currently running fails.
Two server host machines can be running pbs_server at the same time. The two servers have their torque/server_priv directory mounted on a shared NFS file system. The pbs_server's need to be started with the --ha command line option that will allow two servers to be running at the same time. Only the first server to start will complete the full startup. The second server to start will block very early in the startup when it tries to lock the file torque/server_priv/server.lock. When the second server cannot obtain the lock, it will spin in a loop and sleep waiting for the lock to clear. The sleep time between checks of the lock file isone second.
