CATA: Criticality aware task acceleration for multicore processors
Castillo, Emilio; Moretó Planas, Miquel; Casas, Marc; Álvarez Martí, Lluc; Vallejo, Enrique; Chronaki, Kallia; Badia Sala, Rosa Maria; Bosque Orero, José Luis; Beivide Palacio, Julio Ramón; Ayguadé Parra, Eduard; Labarta Mancho, Jesús José; Valero Cortés, Mateo (Institute of Electrical and Electronics Engineers (IEEE), 2016)
Text en actes de congrés
Accés obertManaging criticality in task-based programming models opens a wide range of performance and power optimization opportunities in future manycore systems. Criticality aware task schedulers can benefit from these opportunities ... -
Contention-based nonminimal adaptive routing in high-radix networks
Fuentes Sáez, Pablo; Vallejo, Enrique; García, Marina; Beivide Palacio, Julio Ramón; Rodríguez, Germán; Minkenberg, Cyriel; Valero Cortés, Mateo (Institute of Electrical and Electronics Engineers (IEEE), 2015)
Text en actes de congrés
Accés obertAdaptive routing is an efficient congestion avoidance mechanism for modern Datacenter and HPC networks. Congestion detection traditionally relies on the occupancy of the router queues. However, this approach can hinder ... -
Efficient routing mechanisms for Dragonfly networks
García, Marina; Vallejo, Enrique; Beivide Palacio, Julio Ramón; Odriozola, Miguel; Valero Cortés, Mateo (Institute of Electrical and Electronics Engineers (IEEE), 2013)
Comunicació de congrés
Accés obertHigh-radix hierarchical networks are cost-effective topologies for large scale computers. In such networks, routers are organized in super nodes, with local and global interconnections. These networks, known as Dragonflies, ... -
Global misrouting policies in two-level hierarchical networks
Garcia, Marina; Vallejo, Enrique; Beivide Palacio, Julio Ramón; Odriozola, Miguel; Camarero Coterillo, Cristobal; Valero Cortés, Mateo; Labarta Mancho, Jesús José; Rodríguez, Germán (2013)
Text en actes de congrés
Accés restringit per política de l'editorialDragonfly networks are composed of interconnected groups of routers. Adaptive routing allows packets to be forwarded minimally or non-minimally adapting to the traffic conditions in the network. While minimal routing sends ... -
Light NUCA: a proposal for bridging the inter-cache latency gap
Suárez, Dario; Monreal Arnal, Teresa; Vallejo, Fernando; Beivide Palacio, Julio Ramón; Viñals Yufera, Víctor (IEEE Computer Society, 2009)
Comunicació de congrés
Accés obertTo deal with the “memory wall” problem, microprocessors include large secondary on-chip caches. But as these caches enlarge, they originate a new latency gap between them and fast L1 caches (inter-cache latency gap). ... -
On-the-fly adaptive routing for dragonfly interconnection networks
García, Marina; Vallejo, Enrique; Beivide Palacio, Julio Ramón; Camarero Coterillo, Cristobal; Valero Cortés, Mateo; Rodríguez Herrera, Germán; Minkenberg, Cyriel (2015-03-01)
Article
Accés obertAdaptive deadlock-free routing mechanisms are required to handle variable traffic patterns in dragonfly networks. However, distance-based deadlock avoidance mechanisms typically employed in Dragonflies increase the router ... -
Peripheral twists for torus topologies with arbitrary aspect ratio
Vallejo Gutiérrez, Enrique; Moretó Planas, Miquel; Martínez, Carmen; Beivide Palacio, Julio Ramón (2011)
Text en actes de congrés
Accés obertA torus is a common topology used in supercomputer networks. Asymmetric Tori suffer from resource usage imbalance, which translates to reduced performance. Twisted Tori employ a twist in the peripheral links of one or more ... -
Symmetric L-graphs
Camarero, Cristóbal; Martínez, Carmen; Beivide Palacio, Julio Ramón (Iniciativa Digital Politècnica, 2011)
Text en actes de congrés
Accés obertIn this paper we characterize symmetric L-graphs, which are either Kronecker products of two cycles or Gaussian graphs. Vertex symmetric networks have the property that the communication load is uniformly distributed on ... -
Task mapping in rectangular twisted tori
Camarero Coterillo, Cristobal; Vallejo, Enrique; Martínez Fernández, Maria del Carmen; Moretó Planas, Miquel; Beivide Palacio, Julio Ramón (Association for Computing Machinery (ACM), 2013)
Text en actes de congrés
Accés obertTwisted torus topologies have been proposed as an alternative to toroidal rectangular networks, improving distance parameters and providing network symmetry. However, twisting is apparently less amenable to task mapping ...
