Energy efficiency and awareness of power utilization are significant challenges while building up a cloud computing infrastructure and next-generation data centers. Consolidating Virtual Machines (VMs) is frequently used to lessen data centers’ negative ...

This is an abstract accompanying a poster and a full paper. We introduce an approach to diagnose performance issues in dynamic compilers by logging and comparing optimization decisions.

Modern compilers apply a set of optimization passes aiming to speed up the generated code. The combined effect of individual optimizations is difficult to predict. Thus, changes to a compiler's code may hinder the performance of generated code as an ...

Adopting heterogeneous execution on GPUs and FPGAs in managed runtime systems, such as Java, is a challenging task due to the complexities of the underlying virtual machine. The majority of the current work has been focusing on compiler toolchains to ...

Multi-tiered virtual-machine (VM) environments with Just-In-Time (JIT) compilers are essential for optimizing dynamic language program performance, but comprehending and debugging them is challenging. In this paper, we introduce Derir; a novel tool ...

Now Unmanned Aerial Vehicle (UAV) with Mobile Edge Computing (MEC) severs and Device-to-Device (D2D) communications provide offload computing services for User Devices (UDs). However, the UAV has relatively high transmission latency. And D2D lacks ...

Cloud computing is the use of remote servers on the internet to store, manage, and process data. It is a demand-based service where users need to pay only for what they use. Cloud computing users are extensively distributed throughout the globe, so it ...

Virtual Machines (VM) tend to evolve over their life cycle with features being added regularly and a growing footprint. In a VM designed for resource constrained environments this trend deteriorates the VM’s primary quality. We present how extensibility ...

Due to increased demand from researchers working with highly sensitive data, UC Berkeley developed the Secure Research Data and Compute (SRDC) platform and service. This article describes the design and architecture of the platform as well as key use ...

Adapting a dynamic load dissemination system for distributed computing pasture has become a hot spot problem of current research. In the instance of overloaded VM’s or node failure, the associated resources face difficult to determine which VM should ...

During the last decade, managed runtime systems have been constantly evolving to become capable of exploiting underlying hardware accelerators, such as GPUs and FPGAs. Regardless of the programming language and their corresponding runtime systems, the ...

Dynamic resource allocation of cloud data centers is implemented with the use of virtual machine migration. Selected virtual machines (VM) should be migrated on appropriate destination servers. This is a critical step and should be performed according ...

MoarVM was born out of youthful arrogance. I was contributing to Raku (then Perl 6) compiler development, looking at the Parrot virtual machine we were targeting at the time, considering some of our challenges with it (especially regarding performance ...

Compact language implementations are increasingly popular for use in resource constrained environments. For embedded applications such as robotics and home automation, it is useful to support a Read-Eval-Print-Loop (REPL) so that a basic level of ...

Due to their lower startup latencies and finer-grain pricing than virtual machines (VMs), Amazon Lambdas and other cloud functions (CFs) have been identified as ideal candidates for handling unexpected spikes in simple, stateless workloads. However, it ...

Dart might be the only contemporary programming language that changed its core principles so radically between two major versions. 10 years ago, in 2010, it was born as a dynamically typed programming language with optional static types - ideas of ...

n the early days of the Eclipse OMR project, we created the unimaginatively named JitBuilder API aiming to make it easier to build a JIT compiler. JitBuilder has been used to create prototype JIT compilers in a few thousand lines of C++ for WebAssembly, ...

The main aim of Internet of Things (IoT) is to get every “thing” (sensors, smart cameras, wearable devices, and smart home appliances) to connect to the internet. Henceforth to produce the high volume of data required for data processing between IoT ...

In an IaaS cloud, the dynamic VM scheduler observes and mitigates resource hotspots to maintain performance in an oversubscribed environment. Most systems are focused on schedulers that fit very large infrastructures, which lead to workload-dependent ...

With the exponential growth in cloud computing, the steadily increasing amount of power consumption due to the use of physical and virtual machines is becoming a serious challenge. In this context, we report a study on optimizing the power and energy ...
