Abstract
Systems and methods are described for improving portability of checkpoints of an application using central processing unit (CPU)-specific features. In an example, a system includes a source computing system and a destination computing system. The source computing system may be configured to: cause a first execution of an application that includes a function associated with a plurality of implementations; receive a request to resolve an implementation decision for the function; select, based on a set of source CPU-specific features, a source-specific implementation for the first execution of the function; patch, by rendering a resolved callsite table, a call site associated with the function with an address of the source-specific implementation; and send, to a destination computing system, a checkpoint of the application that includes the resolved callsite table. The destination computing system is configured to restore the application by changing the implementation decision based on a set of destination CPU-specific features.
