Bandwidth of crossbar and multiple-bus connections for multiprocessors
(1982-12)
Article
Accés obertIn this paper we compare the effective bandwidth in a multiprocessor with shared memory using as interconnection networks the crossbar or the multiple-bus. We consider a system with N processors and N memory modules, in ... -
Contention-aware application performance prediction for disaggregated memory systems
(Association for Computing Machinery (ACM), 2020)
Text en actes de congrés
Accés obertDisaggregated memory has recently been proposed as a way to allow flexible and fine-grained allocation of memory capacity to compute jobs. This paper makes an important step towards effective resource allocation on ... -
HPC benchmarking: scaling right and looking beyond the average
(Springer, 2018)
Text en actes de congrés
Accés obertDesigning a balanced HPC system requires an understanding of the dominant performance bottlenecks. There is as yet no well established methodology for a unified evaluation of HPC systems and workloads that quantifies the ... -
Parallel frame rendering: trading responsiveness for energy on a mobile GPU
(2013)
Text en actes de congrés
Accés restringit per política de l'editorialPerhaps one of the most important design aspects for smartphones and tablets is improving their energy efficiency. Unfortunately, rich media content applications typically put significant pressure to the GPU's memory ... -
PROFET: modeling system performance and energy without simulating the CPU
(2019-06)
Article
Accés obertThe approaching end of DRAM scaling and expansion of emerging memory technologies is motivating a lot of research in future memory systems. Novel memory systems are typically explored by hardware simulators that are slow ... -
Profiling memory vulnerability of big-data applications
(Institute of Electrical and Electronics Engineers (IEEE), 2016)
Text en actes de congrés
Accés restringit per política de l'editorialMotivated by the increasing popularity of hosting in-memory big-data analytics in cloud, we present a profiling methodology that can understand how different memory subsystems, i.e., cache and memory bandwidth, are susceptible ... -
Short reasons for long vectors in HPC CPUs: a study based on RISC-V
(Association for Computing Machinery (ACM), 2023)
Text en actes de congrés
Accés obertFor years, SIMD/vector units have enhanced the capabilities of modern CPUs in High-Performance Computing (HPC) and mobile technology. Typical commercially-available SIMD units process up to 8 double-precision elements with ...
