Asynchronous scalable version of the Global-Local non-invasive coupling
Ahmed El Kerim, Pierre Gosselet, Frederic Magoules
The Global-Local non-invasive coupling is an improvement of the submodeling technique, which permits to locally enhance structure computations by introducing patches with refined m…
JACK2: a new high-level communication library for parallel iterative methods
Guillaume Gbikpi-Benissan, Frederic Magoules
In this paper, we address the problem of designing a distributed application meant to run both classical and asynchronous iterations. MPI libraries are very popular and widely used…
Distributed asynchronous convergence detection without detection protocol
Guillaume Gbikpi-Benissan, Frederic Magoules
In this paper, we address the problem of detecting the moment when an ongoing asynchronous parallel iterative process can be terminated to provide a sufficiently precise solution t…
Asynchronous parareal time discretization for partial differential equations
Frederic Magoules, Guillaume Gbikpi-Benissan
Asynchronous iterations are more and more investigated for both scaling and fault-resilience purpose on high performance computing platforms. While so far, they have been exclusive…
Recent Developments in Iterative Methods for Reducing Synchronization
Qinmeng Zou, Frederic Magoules
On modern parallel architectures, the cost of synchronization among processors can often dominate the cost of floating-point computation. Several modifications of the existing meth…
Convergence Detection of Asynchronous Iterations based on Modified Recursive Doubling
Qinmeng Zou, Frederic Magoules
This paper addresses the distributed convergence detection problem in asynchronous iterations. A modified recursive doubling algorithm is investigated in order to adapt to the non-…
