Access to streams in multiprocessor systems
(Institute of Electrical and Electronics Engineers (IEEE), 1993)
Text en actes de congrés
Accés obertWhen accessing streams in vector multiprocessor machines, degradation in the interconnection network and conflicts in the memory modules are the factors that reduce the efficiency of the system. In this paper, we present ... -
Access to vectors in multi-module memories
(Institute of Electrical and Electronics Engineers (IEEE), 1994)
Text en actes de congrés
Accés obertThe poor bandwidth obtained from memory when conflicts arise in the modules or in the interconnection network degrades the performance of computers. Address transformation schemes, such as interleaving, skewing and linear ... -
Achieving high memory performance from heterogeneous architectures with the SARC programming model
(ACM, 2009)
Comunicació de congrés
Accés restringit per política de l'editorialCurrent heterogeneous multicore architectures, including the Cell/B.E., GPUs, and future developments, like Larrabee, require enormous programming efforts to efficiently run current parallel applications, achieving high ... -
ACOTES project: Advanced compiler technologies for embedded streaming
(2011-04)
Article
Accés obertStreaming applications are built of data-driven, computational components, consuming and producing unbounded data streams. Streaming oriented systems have become dominant in a wide range of domains, including embedded ... -
Adaptive and architecture-independent task granularity for recursive applications
(Springer, 2017)
Text en actes de congrés
Accés obertIn the last few decades, modern applications have become larger and more complex. Among the users of these applications, the need to simplify the process of identifying units of work increased as well. With the approach ... -
Adaptive MapReduce scheduling in shared environments
(Institute of Electrical and Electronics Engineers (IEEE), 2014)
Text en actes de congrés
Accés obertIn this paper we present a MapReduce task scheduler for shared environments in which MapReduce is executed along with other resource-consuming workloads, such as transactional applications. All workloads may potentially ... -
Advanced pattern based memory controller for FPGA based HPC applications
(Institute of Electrical and Electronics Engineers (IEEE), 2014)
Text en actes de congrés
Accés restringit per política de l'editorialThe ever-increasing complexity of high-performance computing applications limits performance due to memory constraints in FPGAs. To address this issue, we propose the Advanced Pattern based Memory Controller (APMC), which ... -
Aeneas: A tool to enable applications to effectively use non-relational databases
(Elsevier, 2013)
Text en actes de congrés
Accés obertNon-relational databases arise as a solution to solve the scalability problems of relational databases when dealing with big data applications. However, they are highly configurable prone to user decisions that can heavily ... -
Align and distribute-based linear loop transformations
(Springer, 1993)
Text en actes de congrés
Accés obertIn this paper we generalize the framework of linear loop transformations in the sense that loop alignment is considered as a new component in the transformation process. The aim is to match the structure of loop nests with ... -
ALOJA: a systematic study of Hadoop deployment variables to enable automated characterization of cost-effectiveness
