Asynchronous dynamic compilation based on multi-session profiling to produce shared native code

A non-transitory computer-readable storage medium comprising a plurality of instructions, the plurality of instructions comprising:

• instructions to each session in a plurality of sessions to update a multi-session counter in response to an interpreter executing within said each session, a given method comprising a plurality of to-be-interpreted instructions;
• wherein on execution of the instructions, the multi-session counter is updated by multiple sessions concurrently or simultaneously without locking, wherein in the event that one session starts updating the multi-session counter before another session finishes updating the multi-session counter, the multi-session counter becomes inaccurate relative to a number of interpretations of the given method in the plurality of sessions;
• instructions to a common process compiling the given method to obtain compiled software, in response to the multi-session counter exceeding a preset limit, regardless of whether the multi-session counter has become inaccurate;
• and
• instructions to said each session to execute the compiled software from a shared memory accessible to the plurality of sessions, after completion of compiling by the common process.

An apparatus for creating and executing machine instructions, the apparatus comprising:

• means for each session in a plurality of sessions for updating a multi-session counter in response to an interpreter executing a predetermined software within said each session;
• wherein the multi-session counter is updated by the means of multiple sessions concurrently or simultaneously without locking, wherein in the event that the means of one session starts updating the multi-session counter before the means of another session finishes updating the multi-session counter, the multi-session counter becomes inaccurate relative to a number of interpretations of the predetermined software in the plurality of sessions;
• means for a common process for compiling the predetermined software to obtain compiled software comprising machine instructions, in response to the multi-session counter exceeding a preset limit, regardless of whether the multi-session counter has become inaccurate;
• and
• means for said each session for executing the compiled software from a shared memory accessible to the plurality of sessions, after completion of compiling by the common process.
