Graph Chatbot

Chattez avec Graph Search

Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.

AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.

OLTP in Wonderland -- Where do cache misses come from in major OLTP components?

Anastasia Ailamaki, Pinar Tözün

For several decades, online transaction processing has been one of the main applications that drives innovations in the data management ecosystem, and in turn the database and computer architecture communities. Despite the novel approaches from industry an ...

ACM2013

Arsenic 2p core-level shifts at GaAs/Al2O3 interfaces are determined with respect to bulk GaAs through density functional calculations. Atomistic interface models are constructed in which As atoms are found in various chemical environments. Both Ga-termina ...

OLTP on Hardware Islands

Anastasia Ailamaki, Miguel Sérgio De Oliveira Branco, Pinar Tözün, Ippokratis Pandis, Danica Porobic

Modern hardware is abundantly parallel and increasingly heterogeneous. The numerous processing cores have non-uniform access latencies to the main memory and to the processor caches, which causes variability in the communication costs. Unfortunately, datab ...

SLICC: Self-Assembly of Instruction Cache Collectives for OLTP Workloads

Anastasia Ailamaki, Pinar Tözün

Online transaction processing (OLTP) is at the core of many data center applications. OLTP workloads are known to have large instruction footprints that foil existing L1 instruction caches resulting in poor overall performance. Prefetching can reduce the i ...

SQPR: Stream query planning with reuse

Daniel Kuhn, Wolfram Wiesemann

When users submit new queries to a distributed stream processing system (DSPS), a query planner must allocate physical resources, such as CPU cores, memory and network bandwidth, from a set of hosts to queries. Allocation decisions must provide the correct ...

IEEE2011

When it comes to performance, embedded systems share many problems with their higher-end counterparts. The growing gap between top processor frequency and memory access speed, the memory wall, is one such problem. Driven, in part, by low energy consumption ...

Performance and Energy Trade-offs Analysis of L2 on-Chip Cache Architectures for Embedded MPSoCs

Martino Ruggiero, Mohamed Mostafa Sabry Aly, Pablo Garcia del Valle

On-chip memory organization is one of the most important aspects that can influence the overall system behavior in multi-processor systems. Following the trend set by high-performance processors, high-end embedded cores are moving from single-level on chip ...

Reactive NUCA: Near-Optimal Block Placement and Replication in Distributed Caches

Anastasia Ailamaki, Babak Falsafi, Michael Ferdman

Increases in on-chip communication delay and the large working sets of server and scientific workloads complicate the design of the on-chip last- level cache for multicore processors. The large working sets favor a shared cache design that maximizes the ag ...

Dynamic Capacity-Speed Tradeoffs in SMT Processor Caches

Caches are designed to provide the best tradeoff between access speed and capacity for a set of target applications. Unfortunately, different applications, and even different phases within the same application, may require a different capacity-speed tradeo ...
