Abstract: A system and method are disclosed for improving the performance of compiled Java code. A native code management module determines the available processor resources associated with a target information processing system, their respective instruction set architecture (ISA), and possible native code compilation optimization processes. The native code management module then generates compiler parameter permutations, which are iteratively provided to a just-in-time (JIT) compiler. Each compiler parameter permutation is used by JIT compiler to generate a native code compilation iteration. Each of the resulting native code compilation iterations are executed by the JVM and their respective performance is measured to determine the best performing native code compilation iteration.

Abstract: A system and method for efficient garbage collection. A general-purpose central processing unit (CPU) sends a garbage collection request and a first log to a special processing unit (SPU). The first log includes an address and a data size of each allocated data object stored in a heap in memory corresponding to the CPU. The SPU has a single instruction multiple data (SIMD) parallel architecture and may be a graphics processing unit (GPU). The SPU efficiently performs operations of a garbage collection algorithm due to its architecture on a local representation of the data objects stored in the memory. The SPU records a list of changes it performs to remove dead data objects and compact live data objects. This list is subsequently sent to the CPU, which performs the included operations.

Abstract: A processor including an execution core for executing instructions. In one embodiment, the instructions cause the core to enable two or more virtual machine guests to execute under the control of a virtual machine monitor. A first virtual machine guest includes a first portion of an application executing in the context of a first guest operating system. The first portion of the application creates a guest virtual machine applet that executes in the context of a second virtual machine guest. The first portion of the application and the guest virtual machine applet are part of a single application. To create a guest virtual machine applet, the first portion of the application executes a call to the first guest operating system and in response to receiving the call from the first portion of the application, the first guest operating system makes a system call to the virtual machine monitor.

Abstract: A system and method are disclosed for improving the performance of compiled Java code. Java source code is annotated and then compiled by a Java compiler to produce annotated Java bytecode, which in turn is compiled by a just-in-time (JIT) compiler into annotated native code. The execution of the annotated native code is monitored with a patching agent, which captures the annotated native code as it is being executed. The captured native code is then provided through an application program interface to a dynamic linkage module, which in turn provides the captured native code to a user or to an application plug-in module for modifications. The modifications are saved as a patch. The annotated native code is then re-executed and the modifications to the annotated native code are applied as a patch by the patching agent.
