VIRTUAL MACHINE FAILOVER WITH DISAGGREGATED SHARED MEMORY - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240095186 titled 'VIRTUAL MACHINE FAILOVER WITH DISAGGREGATED SHARED MEMORY

Simplified Explanation

The abstract describes a computer-implemented method that involves operating a program on a virtual machine on a first device with a local cache memory. Depending on the expiration of an epoch timer, updates are written to the local cache memory and evicted items are transmitted to a shared memory device. If the epoch timer expires, the local cache memory is flushed to the shared memory device, the virtual CPU state is transmitted, and the epoch timer is reset.

• Operating a program on a virtual machine on a device with a local cache memory
• Writing updates to the local cache memory and transmitting evicted items to a shared memory device
• Flushing the local cache memory to the shared memory device when the epoch timer expires
• Transmitting the virtual CPU state to the shared memory device
• Resetting the epoch timer

Original Abstract Submitted

according to an aspect, a computer-implemented method includes operating a program on a virtual machine on a first device having a local cache memory. based on a determination that an epoch timer has not expired, aspects include writing one or more updates to the local cache memory and transmitting evicted items from the local cache memory to a shared memory device that is separate from the first device. based on a determination that an epoch timer has expired, aspects include flushing the local cache memory to the shared memory device, transmitting a virtual cpu state of the virtual machine to the shared memory device, and resetting the epoch timer.
