Node-Type-Based Load-Balancing Routing for Parallel Generalized Fat-Trees
John Gliksberg, Jean-Noel Quintin, Pedro Javier Garcia
High-Performance Computing (HPC) clusters are made up of a variety of node types (usually compute, I/O, service, and GPGPU nodes) and applications don't use nodes of a different ty…
High-Quality Fault-Resiliency in Fat-Tree Networks (Extended Abstract)
John Gliksberg, Antoine Capra, Alexandre Louvet +2
Coupling regular topologies with optimized routing algorithms is key in pushing the performance of interconnection networks of HPC systems. In this paper we present Dmodc, a fast d…
Self-stabilization and byzantine tolerance for maximal independent
Johanne Cohen, Laurence Pilard, François Pirot +1
We analyze the impact of transient and Byzantine faults on the construction of a maximal independent set in a general network. We adapt the self-stabilizing algorithm presented by…
The Positive Effects of Stochastic Rounding in Numerical Algorithms
El-Mehdi El Arar, Devan Sohier, Pablo de Oliveira Castro +1
Recently, stochastic rounding (SR) has been implemented in specialized hardware but most current computing nodes do not yet support this rounding mode. Several works empirically il…
