Techniques for epoch pipelining are disclosed. In one particular exemplary embodiment, the techniques may be realized as a method for epoch pipelining comprising the steps of beginning a first epoch, determining for one or more pages of memory if the pages of memory are likely to be modified in a subsequent epoch, performing a first operation on the pages of memory that are likely to be modified in a subsequent epoch, beginning a second epoch, subsequent to the first epoch, performing a second operation on the pages of memory that are not likely to be modified in a subsequent epoch, and ending the first epoch, wherein the first operation and the second operation are dissimilar.

Method and apparatus for transactional fault tolerance in a client-server system is described. In one example, output data generated by execution of a service on a primary server during a current epoch between a first checkpoint and a second checkpoint is buffered. A copy of an execution context of the primary server is established on a secondary server in response to the second checkpoint. The output data as buffered is released from the primary server in response to establishment of the copy of the execution context on the secondary server.
