Abstract
A method of (and system for) recovering the state of a failed node in a distributed shared memory system, includes directing a flush of data from a failed node, and flushing the data from the failed node to a memory node.
Claims22
A method of recovering the state of a failed node in a distributed shared memory system, comprising:
- directing a flush of data from a failed node;
- and
- flushing said data from said failed node to a memory node,
- wherein said flushing includes performing a local flush on said failed node followed by a remote flush.
A system for recovering a state of a failed node in a distributed shared memory system, comprising:
- a controller for directing a flush of data from a failed node;
- and
- a flush engine for flushing said data from said failed node to a memory node,
- wherein said flush engine includes a local flush engine for performing a local flush on said failed node and a remote flush engine for performing, after said local flush a remote flush.
A system for recovering a state of a failed node in a distributed shared memory system, comprising:
- means for directing a flush of data from a failed node;
- and
- means for flushing said data from said failed node to a memory node,
- wherein said flushing means includes a local flush engine for performing a local flush on said failed node and a remote flush engine for performing, after said local flush, a remote flush.
A signal-bearing medium tangibly embodying a program of machine-readable instructions executable by a digital processing apparatus to perform a method of recovering the state of a failed node in a distributed shared memory system, comprising:
- directing a flush of data from a failed node;
- and
- flushing said data from said failed node to a memory node,
- wherein said flushing includes performing a local flush on said failed node followed by a remote flush.
