Resilient MPI applications using an application-level checkpointing framework and ULFM
(Springer New York LLC, 2017-01)
[Abstract] Future exascale systems, formed by millions of cores, will present high failure rates, and long-running applications will need to make use of new fault tolerance techniques to ensure successful execution completion. ...
A Grid Portal for an Undergraduate Parallel Programming Course
(Institute of Electrical and Electronics Engineers, 2005-08)
[Abstract] This paper describes an experience of designing and implementing a portal to support transparent remote access to supercomputing facilities to students enrolled in an undergraduate parallel programming course. ...
Analysis of Performance-impacting Factors on Checkpointing Frameworks: The CPPC Case Study
(Oxford University Press, 2011-11-01)
[Abstract] This paper focuses on the performance evaluation of Compiler for Portable Checkpointing (CPPC), a tool for the checkpointing of parallel message-passing applications. Its performance and the factors that impact ...
A Heuristic Approach for the Automatic Insertion of Checkpoints in Message-Passing Codes
(Technische Universitaet Graz * Institut fuer Informationssysteme und Computer Medien,Graz University of Technology, Institute for Information Systems and Computer Media, 2009-08)
[Abstract] Checkpointing tools may be typically implemented at two different abstraction levels: at the system level or at the application level. The latter has become a more popular alternative due to its flexibility and ...
Improving Scalability of Application-Level Checkpoint-Recovery by Reducing Checkpoint Sizes
(Springer Japan KK, 2013)
[Abstract] The execution times of large-scale parallel applications on nowadays multi/many-core systems are usually longer than the mean time between failures. Therefore, parallel applications must tolerate hardware failures ...
Toxo: A Library for Calculating Penetrance Tables of High-Order Epistasis Models
(BioMed Central Ltd., 2020-04-09)
[Abstract]
Background
Epistasis is defined as the interaction between different genes when expressing a specific phenotype. The most common way to characterize an epistatic relationship is using a penetrance table, which ...
Enhanced global optimization methods applied to complex fisheries stock assessment models
(Elsevier BV, 2019-04)
[Abstract]
Statistical fisheries models are frequently used by researchers and agencies to understand the behavior of marine ecosystems or to estimate the maximum acceptable catch of different species of commercial interest. ...
Assessing resilient versus stop-and-restart fault-tolerant solutions in MPI applications
(Springer New York LLC, 2017-01)
[Abstract] The Message Passing Interface (MPI) standard is the most popular parallel programming model for distributed systems. However, it lacks fault-tolerance support and, traditionally, failures are addressed with ...
Novel parallelization of simulated annealing and Hooke & Jeeves search algorithms for multicore systems with application to complex fisheries stock assessment models
(Elsevier Ltd, 2016-11)
[Abstract] Estimating parameters of a statistical fisheries assessment model typically involves a comparison of disparate datasets to a forward simulation model through a likelihood function. In all but trivial cases the ...
Reducing the overhead of an MPI application-level migration approach
(Elsevier BV * North-Holland, 2016)
[Abstract] Process migration provides many benefits for parallel environments including dynamic load balance, data access locality, or fault tolerance. This work proposes a solution that reduces the memory and I/O overhead ...
