Remote Memory Access (RMA) hardware allow a given motherboard in a cluster to directly access the memory installed in a remote motherboard of the same cluster. In recent works, this characteristic has been used to extend ...

Cluster computers represent a cost-effective alternative solution to supercomputers. In these systems, it is common to constrain the memory address space of a given processor to the local motherboard. Constraining the ...

[ES] Analizar el impacto de permitir que las tareas de tiempo real puedan migrar su ejecución de un core a otro, sobre el consumo en sistemas empotrados multicore.

[EN] Shared caches have become the common design choice in the vast majority of modern multi-core and many-core processors, since cache sharing improves throughput for a given silicon area. Sharing the cache, however, has ...

Power consumption is a major design concern in current embedded systems. To deal with consumption, many systems apply dynamic voltage scaling (DVS) techniques which dynamically change the system speed depending on the ...

[EN] The fast evolution of multicore processors makes it difficult for professors to offer computer architecture courses with updated contents. To deal with this shortcoming that could discourage students, the most appropriate ...

Out-of-order retirement of instructions has been shown to be an effective technique to increase the number of in-flight instructions. This form of runtime scheduling can reduce pipeline stalls caused by head-of-line blocking ...

[EN] Real-time tasks have experience a significant complexity increase in the last years. We can find examples of real-time tasks in nowadays systems that control self-driving cars or multimedia systems, among others. To ...

Photonic interconnects are a promising solution for the so-called communication bottleneck in current Chip Multiprocessor (CMPs) architectures. This technology presents an inherent low-latency and power consumption almost ...

[EN] Current multicore systems implement various hardware prefetchers since prefetching can significantly hide the huge main memory latencies. However, memory bandwidth is a scarce resource which becomes critical with ...
