摘要
A computer-implemented method is provided for compilation rescheduling from among four compilation levels comprising level 1, level 2, level 3, and level 4 on a parallel distributed computing framework running processes for a plurality of jobs of a virtual machine. The method bypasses a program analysis overhead that includes measuring a compiled method execution time by identifying completed compilation levels of a Just In Time compilation. The method finds a repetition of a same process in the processes for the plurality of jobs of the virtual machine from profiles by comparing main class names, virtual machine parameters, and Jar file types therein. The method applies a compilation scheduling for the same process a next time the same process runs based on a result of the checking the transition, by (i) compiling at the level 1 at least some methods for the same process responsive to the virtual machine finishing without compiling the at least some methods for the same process at the level 4 after compiling the at least some of the methods at a level in between the level 1 and the level 4, and (ii) compiling at the level 4 at least a subset of the methods earlier than an original scheduled time responsive to at least the subset of the methods compiled at the level 4 being infrequently invoked below a threshold amount.
