Interconnection networks usually consist of a fabric of interconnected routers, which receive packets arriving at their input ports and forward them to appropriate output ports. Unfortunately, network packets moving through ...

[ES] Los lenguajes PGAS han demostrado ser una forma intuitiva de programación paralela. Con GASNet, una capa de red independiente del lenguaje, preocupaciones por la compatibilidad ya no son ningún problema, ya que GASNet ...

Improvements in parallel computing hardware usually involve increments in the number of available resources for a given application such as the number of computing cores and the amount of memory. In the case of shared-memory ...

Using GPUs reduces execution time of many applications but increases acquisition cost and power consumption. Furthermore, GPUs usually attain a relatively low utilization. In this context, remote GPU virtualization ...

Este estudio se centra en la granularidad de las comunicaciones en aplicaciones MPI. Nuestra hipótesis consiste en que la granularidad óptima para una red exterior al chip no es la óptima para una red interior al chip. ...

[EN] The computing power of supercomputers and data centers has noticeably grown during the last decades at the cost of an ever increasing energy demand. The need for energy (and power) of these facilities has finally ...

La presencia de Unidades de Proceso Gráfico (Graphics Processing Units, GPUs) en las instalaciones de Computación de Alto Rendimiento (High Performance Computing, HPC) es una opción cada vez más extendida por la mejora del ...

[EN] A clear trend has emerged involving the acceleration of scientific applications by using GPUs. However, the capabilities of these devices are still generally underutilized. Remote GPU virtualization techniques can ...

[EN] The high-performance computing domain is enriching with the inclusion of networks-on-chip (NoCs) as a key component of many-core (CMPs or MPSoCs) architectures. NoCs face the communication scalability challenge while ...
