Ab Initio Technology Assigned Patent

Ab Initio Technology, LLC, Lexington, MA, has been assigned a patent (9,678,834) developed by Stanfill, Craig W., Lincoln, MA, for a “recovery and fault-tolerance under computational indeterminism.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A method for promoting fault tolerance and recovery in a computing system including at least one processing node includes promoting availability and recovery of a first processing node, by, at the first processing node, generating first spawn using a spawner that has been assigned a first generation-indicator so that its spawn inherits the first generation indicator, beginning a checkpoint interval to generate nodal recovery information, suspending the spawner from generating spawn, assigning, to the spawner, a second generation-indicator that differs from the first one, resuming the spawner, so that it generates second spawn that inherits the second generation-indicator, controlling an extent to which the second spawn writes to memory, and after committing nodal recovery information acquired during the checkpoint to durable storage, releasing control over the extent to which the second spawn can write to memory.“

The patent application was filed on October 19, 2015 (14/886,363).
