Network unfairness in dragonfly topologies
Fuentes, Pablo; Vallejo, Enrique; Camarero, Cristóbal; Beivide Palacio, Ramon; Valero Cortés, Mateo (2016-12)
Article
Accés obertDragonfly networks arrange network routers in a two-level hierarchy, providing a competitive cost-performance solution for large systems. Non-minimal adaptive routing (adaptive misrouting) is employed to fully exploit the ... -
OFAR-CM: Efficient Dragonfly networks with simple congestion management
García, Marina; Vallejo, Enrique; Beivide Palacio, Ramon; Valero Cortés, Mateo; Rodríguez, Germán (Institute of Electrical and Electronics Engineers (IEEE), 2013)
Text en actes de congrés
Accés obertDragonfly networks are appealing topologies for large-scale Data center and HPC networks, that provide high throughput with low diameter and moderate cost. However, they are prone to congestion under certain frequent traffic ... -
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 ... -
Solving multiprocessor drawbacks with kilo-instruction processors
Vallejo, Enrique; Galluzzi, Marco; Cristal Kestelman, Adrián; Vallejo, Fernando; Beivide Palacio, Ramon; Stenström, Per; Smith, James E.; Valero Cortés, Mateo (2005)
Report de recerca
Accés obertNowadays, a good multiprocessor system design has to deal with many drawbacks in order to achieve a good tradeoff between complexity and performance. For example, while solving problems like coherence and consistency is ... -
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 ... -

Throughput unfairness in Dragonfly networks under realistic traffic patterns
Fuentes, Pablo; Vallejo, Enrique; Camarero, Cristóbal; Beivide Palacio, Ramon; Valero Cortés, Mateo (Institute of Electrical and Electronics Engineers (IEEE), 2015)
Text en actes de congrés
Accés obertDragonfly networks have a two-level hierarchical arrangement of the network routers, and allow for a competitive cost-performance solution in large systems. Non-minimal adaptive routing is employed to fully exploit the ... -
Towards fair, scalable, locking
Vallejo, Enrique; Sanyal, Sutirtha; Harris, Tim; Vallejo, Fernando; Beivide Palacio, Ramon; Unsal, Osman Sabri; Cristal Kestelman, Adrián; Valero Cortés, Mateo (2008)
Text en actes de congrés
Accés obertWithout care, Hardware Transactional Memory presents several performance pathologies that can degrade its performance. Among them, writers of commonly read variables can suffer from starvation. Though different solutions ...
