Optimizing job performance under a given power constraint in HPC centers
Etinski, Maja; Corbalán González, Julita; Labarta Mancho, Jesús José; Valero Cortés, Mateo (2010)
Text en actes de congrés
Accés obertNever-ending striving for performance has resulted in a tremendous increase in power consumption of HPC centers. Power budgeting has become very important from several reasons such as reliability, operating costs and limited ... -
Power-aware load balancing of large scale MPI applications
Etinski, Maja; Corbalán González, Julita; Labarta Mancho, Jesús José; Valero Cortés, Mateo; Veidenbaum, Alex (Institute of Electrical and Electronics Engineers (IEEE), 2009)
Text en actes de congrés
Accés obertPower consumption is a very important issue for HPC community, both at the level of one application or at the level of whole workload. Load imbalance of a MPI application can be exploited to save CPU energy without penalizing ... -
Soporte para el análisis de workloads en el proyecto eNANOS
Rodero Castro, Iván; Corbalán González, Julita; Duran González, Alejandro; Labarta Mancho, Jesús José (2005)
Text en actes de congrés
Accés obertEl proyecto eNANOS plantea la planificación coordinada de trabajos entre varios niveles, desde el entorno heterogéneo y dinámico de un Grid hasta la ejecución de procesos y threads en las CPU’s de un computador o un cluster. ... -
Thread fork/join techniques for multi-level parallelism exploitation in NUMA multiprocessors
Martorell Bofill, Xavier; Ayguadé Parra, Eduard; Navarro, Nacho; Corbalán González, Julita; González Tallada, Marc; Labarta Mancho, Jesús José (Association for Computing Machinery (ACM), 1999)
Text en actes de congrés
Accés obertThis paper presents some techniques for efficient thread forking and joining in parallel execution environments, taking into consideration the physical structure of NUMA machines and the support for multi-level parallelization ... -
XtreemOS application execution management: a scalable approach
Nou Castell, Ramon; Giralt Celiméndiz, Jacobo; Corbalán González, Julita; Tejedor Saavedra, Enric; Fitó, Josep Oriol; Perez, Josep Maria; Cortés, Toni (IEEE Press. Institute of Electrical and Electronics Engineers, 2010)
Text en actes de congrés
Accés obertDesigning a job management system for the Grid is a non-trivial task. While a complex middleware can give a lot of features, it often implies sacrificing performance. Such performance loss is especially noticeable for ...
