Predicting and Prefetching Tlb Entries from Irregular Access Streams
This thesis describes the design and evaluation the Irregular Translation Buffer (ITB), which is a prefetcher for translation lookaside buffer (TLB) entries that is based on the Irregular Stream Buffer (ISB) introduced by Jain and Lin [1]. The main idea to use the ISB's improvements in prefetching cache lines from irregular access streams and use them to prefetch entries from irregular access s...
متن کاملAn Entity Resolution Framework for Deduplicating Proteins
An important prerequisite to successfully integrating protein data is detecting duplicate records spread across different databases. In this paper, we describe a new framework for protein entity resolution, called PERF, which deduplicates protein mentions using a wide range of protein attributes. A mention refers to any recorded information about a protein, whether it is derived from a database...
متن کامل8. Algorithms for Hardware Caches and TLB
Over the last 20 years or so CPU clock rates have grown explosively, and CPUs with clock rates exceeding 2 GHz are now available in the mass market. Unfortunately, the speed of main memory has not increased as rapidly: today’s main memory typically has a latency of about 60 ns. This implies that the cost of accessing main memory can be 120 times greater than the cost of performing an operation ...
متن کاملImplementation of Fast Address-Space Switching and TLB Sharing on the StrongARM Processor
The StrongARM processor features virtually-addressed caches and a TLB without address-space tags. A naive implementation therefore requires flushing of all CPU caches and the TLB on each context switch, which is very costly. We present an implementation of fast context switches on the architecture in both Linux and the L4 microkernel. It is based on using domain tags as address-space identifier...
متن کاملqTLB: Looking Inside the Look-Aside Buffer
Rapid evolution of multi-core platforms is putting additional stress on shared processor resources like TLB. TLBs have mostly been private resources for the application running on the core, due to the constant flushing of entries on context switches. Recent technologies like virtualization enable independent execution of software domains leading to performance issues because of interesting dyna...
