Program code allocation based on processor features

A system, comprising:

• a plurality of servers;
• and
• one or more computing devices configured to implement a program execution service, wherein the program execution service is configured to:
• determine whether one or more processor features were invoked by program code executing on one or more servers of the plurality of servers;
• select one or more other servers from the plurality of servers based at least on the determination of whether the one or more processor features were invoked by the program code;
• and
• migrate the program code from the one or more servers to the one or more other servers based on the selection.

A computer-implemented method, comprising:

• performing, by one or more computing devices that collectively implement a program execution service:
• determining whether one or more processor features were invoked by program code executing on one or more servers of a plurality of servers;
• selecting one or more other servers from the plurality of servers based at least on the determination of whether the one or more processor features were invoked by the program code;
• and
• migrating the program code from the one or more servers to the one or more other servers based on the selection.

One or more non-transitory computer-accessible storage media storing program instructions that when executed on or across one or more processors cause the one or more processors to:

• determine whether one or more processor features were invoked by program code executing on one or more servers of a plurality of servers;
• select one or more other servers from the plurality of servers based at least on the determination of whether the one or more processor features were invoked by the program code;
• and
• migrate the program code from the one or more servers to the one or more other servers based on the selection.
