Java has been successful particularly for writing applications in the server environment. However, isolation of multiple applications hasnot been efficiently achieved in Java. Many customers require that their applications are guarded by independent OS ...

Object inlining is an optimization that embeds certain referenced objects into their referencing object. It reduces the costs of field accesses by eliminating unnecessary field loads. The order of objects in the heap is changed in such a way that ...

Aggressive dynamic optimization in high-performance Java Virtual Machines can be hampered by language features like Java's exception model, which requires precise detection and handling of program-generated exceptions. Furthermore, the compile-time ...

We have designed and implemented VMGL, a virtual machine monitor (VMM) independent, graphics processing unit (GPU) independent, and cross-platform OpenGL virtualization solution. VMGL allows applications executing within virtual machines (VMs) to ...

If the operating system could be specialized for every application, many applications would run faster. For example, Java virtual machines (JVMs) provide their own threading model and memory protection, so general-purpose operating system ...

Integrating new resource management policies into operating systems (OSes) is an ongoing process. Despite innovative policy proposals being developed, it is quite difficult to deploy a new one widely because it is difficult, costly and often impractical ...

Several existing dynamic binary analysis tools use shadowmemory-they shadow, in software, every byte of memory used by a program with another value that says something about it. Shadow memory is difficult to implement both efficiently and robustly. ...

With an estimated installation base of around 1 billion units, the Java J2ME platform is one of the largest development targets available. For mobile devices, J2ME is often the only available environment. For the very large body of software written in C ...

The design of new programming languages benefits from interpretation, which can provide a simple initial implementation, flexibility to explore new language features, and portability to many platforms. The only downside is speed of execution, as there ...

Dynamic compilation is typically performed in a separate thread, asynchronously with the remaining application threads. This compilation thread is often scheduled for execution in a simple round-robin fashion either by the operating system or by the ...

Virtualized storage systems are required to service concurrently executing workloads, with potentially diverse data delivery requirements, that are running under multiple operating systems. Although a number of algorithms have been developed for I/O ...

Virtualization provides levels of execution isolation and service partition that are desirable in many usage scenarios, but its associated overheads are a major impediment for wide deployment of virtualized environments. While the virtualization cost ...

Recent advances in software and architectural support for server virtualization have created interest in using this technology in the design of consolidated hosting platforms. Since virtualization enables easier and faster application migration as well ...

PinOS is an extension of the Pin dynamic instrumentation framework for whole-system instrumentation, i.e., to instrument both kernel and user-level code. It achieves this by interposing between the subject system and hardware using virtualization ...

A dynamic binary translator offers solutions for translating and running source architecture binaries on target architecture at runtime. Regardless of its growing popularity, practical dynamic binary translators usually suffer from the limited ...

Virtual machine (VM) technology is experiencing a resurgence due to various benefits including ease of management, security and resource consolidation. Live migration of virtual machines allows transparent movement of OS instances and hosted ...

So far virtual machine (VM) migration has focused on transferring the run-time memory state of the VMs in local area networks (LAN). However, for wide-area network (WAN) migration it is crucial to not just transfer the VMs image but also transfer its ...

A key analysis developed for the compilation of parallel programs is thread escape analysis (hereafter referred to as escape analysis), which determines what objects are accessed in more than one thread, and which references within a program are ...

Commercial Java virtual machines are designed to maximize the performance of applications at the expense of predictability. High throughput garbage collection algorithms, for example, can introduce pauses of 100 milliseconds or more. We are interested ...
