Abstract

Embodiments of the present invention provide efficient systems and methods for scaling past the Java Virtual Machine (JVM) thread limit in a Java Virtual Machine. Embodiments of the present invention can be used to ensure that a received workload is executed, even if the workload is greater than a JVM thread limit of the system, by spawning a reduced number of threads from a main process, in order to provide enough resources for the effective execution of a received workload.

First claim

What is claimed is:

1. A computer program product comprising:
one or more non-transitory computer readable storage media and program instructions stored on the one or more non-transitory computer readable storage media, the program instructions comprising:
program instructions to receive, by a first Java Virtual Machine (JVM) process, a workload for an application, wherein the first JVM process comprises a 32-bit JVM;
program instructions to determine, by a first Java Virtual Machine (JVM) process, whether the workload for the application is above a threading limit;
responsive to the program instructions determining that the workload for the application is above the threading limit, program instructions to determine at least one sub-process from the first JVM process wherein the at least one sub-process from the first JVM process comprises a 32-bit JVM, and wherein a number of the at least one sub-process from the first JVM process is based in part on the workload for the application and wherein each of the at least one sub-process configured to communicate with the first JVM process;
program instructions to spawn by the first JVM process, the determined at least one sub-process from the first JVM process, based on the workload for the application; and
program instructions to coordinate, by the first JVM process, the received workload for the application, using inter-process communication (IPC), wherein IPC includes remote method invocation (RMI).
