Abstract
Official abstract text for this publication.
A method of backstepping through a program execution includes dividing the program execution into a plurality of epochs, wherein the program execution is performed by an active core, determining, during a subsequent epoch of the plurality of epochs, that a rollback is to be performed, performing the rollback including re-executing a previous epoch of the plurality of epochs, wherein the previous epoch includes one or more instructions of the program execution stored by a checkpointing core, and adjusting a granularity of the plurality of epochs according to a frequency of the rollback.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of backstepping through a program execution comprising: dividing the program execution into a plurality of epochs, wherein the program execution is performed by an active core; determining, during a subsequent epoch of the plurality of epochs, that a rollback is to be performed; performing the rollback including re-executing a previous epoch of the plurality of epochs, wherein the previous epoch includes one or more instructions of the program e…
