Technologies for hardware-assisted application checkpointing include a computing device having a processor with hardware checkpoint support. In response to encountering a checkpoint event during execution of an application, the computing device saves the execution state of the application to nonvolatile storage using the hardware checkpoint support. The computing device may also restore the execution state using the hardware checkpoint support. The hardware checkpoint support may save part or all of the virtual memory space of the application in a manner transparent to the executing process. The hardware checkpoint support may be invoked using one or more system hooks such as system calls or processor instructions. The computing device may monitor for checkpoint events using hardware event monitors of the processor, chipset, or other components of the computing device. The computing device may store execution state in a dedicated flash memory cache. Other embodiments are described and claimed.

Hardware-assisted application checkpointing and restoring

Technologies for environment checkpointing include an orchestration node communicatively coupled to one or more working computing nodes. The orchestration node is configured to administer an environment checkpointing event by transmitting a checkpoint initialization signal to each of the one or more working computing nodes that have been registered with the orchestration node. Each working computing node is configured to pause and buffer any presently executing applications, save checkpointing data (an execution state of each of the one or more applications) and transmit the checkpointing data to the orchestration node. Other embodiments are described and claimed.
