A major performance limiter in modern processors is the long latencies caused by data cache misses. Both compiler- and hardware-based prefetching schemes help hide these latencies and so improve performance. Compiler techniques infer memory access patterns through code analysis, and insert appropriate prefetch instructions. Hardware prefetching techniques work independently from the compiler by monitoring an access stream, detecting patterns in this stream and issuing prefetches based on these patterns. This paper looks at the interplay between compiler and hardware architecture-based prefetch

Prefetching is essential to minimizing the number of misses in cache and improving processor performance. Many prefetchers have been proposed, including simple but highly effective stream-based prefetchers and prefetchers that predict complex access patterns based on structures such as history buffers and bit vectors. However, many cache misses still occur in many applications. After analyzing the various techniques in Instruction and Data Prefetcher, several key features were extracted which impact system performance. Data prefetching is an essential technique used in all commercial processor

Data prefetching efficiently reduces the memory access latency in NUCA architectures as the Last Level Cache (LLC) is shared and distributed across multiple cores. But cache pollution generated by prefetcher reduces its efficiency by causing contention for shared resources such as LLC and the underlying network. The paper proposes Zero Pollution Prefetcher (ZPP) that eliminates cache pollution for NUCA architecture. For this purpose, ZPP uses L1 prefetcher and places the prefetched blocks in the data locations of LLC where modified blocks are stored. Since modified blocks in LLC are stale and

Achieving low load-to-use latency with low energy and storage overheads is critical for performance. Existing techniques either prefetch into the pipeline (via address prediction and validation) or provide data reuse in the pipeline (via register sharing or L0 caches). These techniques provide a range of tradeoffs between latency, reuse, and overhead. In this work, we present a pipeline prefetching technique that achieves state-of-the-art performance and data reuse without additional data storage, data movement, or validation overheads by adding address tags to the register file.

— Modern computer processors are equipped with multiple cores, each boasting its own dedicated cache memory, while collectively sharing a generously sized Last Level Cache (LLC). To ensure equitable utilization of the LLC space and bolster system security, partitioning techniques have been introduced to allocate the shared LLC space among the applications running on different cores. This partition dynamically adapts to the requirements of these applications. Prefetching plays a vital role in enhancing cache performance by proactively loading data into the cache before it get requested explicit

Modern embedded systems are packed with dedicated Field Programmable Gate Arrays (FPGAs) to accelerate the overall system performance. However, the FPGAs are susceptible to reconfiguration overheads. The reconfiguration overheads are mainly because of the configuration data being fetched from the off-chip memory at run-time and also due to the improper management of tasks during execution. To reduce these overheads, our proposed methodology mainly focuses on the prefetch heuristic, reuse technique, and the available memory hierarchy to provide an efficient mapping of tasks over the available m

However, since in-order processors lack complex hardware support for tolerating long-latency memory accesses, developing compiler technologies to hide such latencies becomes critical. Compiler-directed prefetching has been demonstrated effective on some applications.

Recording the frequency of items in highly skewed data streams is a fundamental and hot problem in recent years. The literature demonstrates that sketch is the most promising solution. The typical metrics to measure a sketch are accuracy and speed, but existing sketches make only trade-offs between the two dimensions. Our proposed solution is a new sketch framework called Stingy sketch with two key techniques: Bit-pinching Counter Tree ( BCTree ) and Prophet Queue ( PQueue ) which optimizes both the accuracy and speed. The key idea of BCTree is to split a large fixed-size counter into many sma

One widely used metric that measures data locality is reuse distance —the number of unique memory locations that are accessed between two consecutive accesses to a particular memory location. State-of-the-art techniques that measure reuse distance in parallel applications rely on simulators or binary instrumentation tools that incur large performance and memory overheads. Moreover, the existing sampling-based tools are limited to measuring reuse distances of a single thread and discard interactions among threads in multi-threaded programs.

This paper presents and evaluates a two-level web usage prediction technique, consisting of a neural network in the first level and contextual component predictors in the second level. We used Markov chains of different orders as contextual predictors to anticipate the next web access based on specific web access history. The role of the neural network is to decide, based on previous behaviour, whose predictor’s output to use. The predicted web resources are then prefetched into the cache of the browser. In this way, we considerably increase the hit rate of the web browser, which shortens the

Delta compression can complement data deduplication by further minimizing redundancy through the compression of non-duplicate data chunks. When adding delta compression to deduplication-based backup systems, however, two primary challenges arise that degrade performance of inline deduplication. First, extra I/Os are introduced along the critical paths of backup and restoration for retrieving base chunks, slowing the system. Second, rewriting techniques prohibit specific data chunks from serving as base chunks for delta compression to improve restore performance, resulting in a loss of compress

Abstract A Roman stylus tablet discovered at Vindolanda in 2014 preserves the partial text of a deed-of-sale for an enslaved person, only the second such document from Britain. This article presents the results of multiple techniques used to reveal the almost illegible text and proposes a restoration of the format of the document and its lost content, based on more complete examples from Italy and around the Empire. We examine the late first-century archaeological and historical context and suggest that the purchaser is probably the prefect Iulius Verecundus. We consider other possible evidenc

<strong><em>Background</em></strong><em>: Peri-implant disease is a condition of pathological inflammation that develop in the tissue surrounding a load-bearing implant which can lead to loss of the implant itself. Anaerobic plaque bacteria are considered risk factor with negative impacts on the peri-implant tissue health leading to peri-implantitis. Air polishing technique which first introduced as an alternative technique for removing biofilm and supragingival extrinsic stain. </em> <strong><em>Aims</em></strong><em>: define Air polishing technique and indicate the different between peri-imp
