In this paper we introduce a runtime system to allow unmodified multi-threaded applications to use multiple machines. The system allows threads to migrate freely between machines depending on the workload. Our prototype , COMET (Code Offload by Migrating Execution Transparently), is a realization of this design built on top of the Dalvik Virtual Machine.(More)
Approximate computing, where computation accuracy is traded off for better performance or higher data throughput, is one solution that can help data processing keep pace with the current and growing overabundance of information. For particular domains such as multimedia and learning algorithms, approximation is commonly used today. We consider automation to(More)
—With the prevalence of GPUs as throughput engines for data parallel workloads, the landscape of GPU computing is changing significantly. Non-graphics workloads with high memory intensity and irregular access patterns are frequently targeted for acceleration on GPUs. While GPUs provide large numbers of compute resources, the resources needed for memory(More)
To achieve high performance on many-core architectures like GPUs, it is crucial to efficiently utilize the available memory bandwidth. Currently, it is common to use fast, on-chip scratchpad memories, like the shared memory available on GPUs' shader cores, to buffer data for computation. This buffering, however, has some sources of inefficiency that hinder(More)
Approximate computing is an approach where reduced accuracy of results is traded off for increased speed, throughput, or both. Loss of accuracy is not permissible in all computing domains, but there are a growing number of data-intensive domains where the output of programs need not be perfectly correct to provide useful results or even noticeable(More)
INTRODUCTION Some studies in dental literature have proposed that short term and long term exposure of root dentin to calcium hydroxide predisposes it to fracture. Mineral trioxide aggregate (MTA) and a recently introduced endodontic material, calcium-enriched mixture (CEM) cement may be used instead of calcium hydroxide and might have an effect on the(More)
INTRODUCTION Many of highly-alkaline dental materials have some adverse effects on physical properties of dentin. As basic substances, mineral trioxide aggregate (MTA), calcium hydroxide (CH) and the new endodontic material, calcium-enriched mixture (CEM) cement, may adversely affect dentin. The purpose of this in vitro study was to evaluate the effect of(More)
