The Network Agnostic MPI – Scali MPI Connect
2003This paper presents features and performance of Scali MPI Connect (SMC). Key features in SMC are presented, such as dynamic selection of interconnect at runtime, automatic fail-over and runtime selection of optimized collective operations. Performance is measured both for basic communication functions such as bandwidth and latency and for real ...

MPI-Mitten: Enabling Migration Technology in MPI
Sixth IEEE International Symposium on Cluster Computing and the Grid (CCGRID'06), 2006Group communications are commonly used in parallel and distributed environment. However, existing migration mechanisms do not support group communications. This weakness prevents migrationbased proactive fault tolerance, among others, to be applied to MPI applications.

Open MPI: A Flexible High Performance MPI
2006A large number of MPI implementations are currently available, each of which emphasize different aspects of high-performance computing or are intended to solve a specific research problem. The result is a myriad of incompatible MPI implementations, all of which require separate installation, and the combination of which present significant logistical ...

MRI Meets MPI: A Bimodal MPI-MRI Tomograph
IEEE Transactions on Medical Imaging, 2014While magnetic particle imaging (MPI) constitutes a novel biomedical imaging technique for tracking superparamagnetic nanoparticles in vivo, unlike magnetic resonance imaging (MRI), it cannot provide anatomical background information. Until now these two modalities have been performed in separate scanners and image co-registration has been hampered by ...

MPI/CTP: A Reconfigurable MPI for HPC Applications
2006Modern MPI applications have diverse communication requirements, with trends showing that they are moving from static communication requirements to more dynamic and evolving communication requirements. However, MPI libraries, which integrate MPI applications with the hardware, are not flexible enough to accommodate these diverse needs.

Proceedings of the 28th ACM international conference on Supercomputing, 2014
Many-core architectures, such as the Intel Xeon Phi, provide dozens of cores and hundreds of hardware threads. To utilize such architectures, application programmers are increasingly looking at hybrid programming models, where multiple threads interact with the MPI library (frequently called "MPI+X" models).

Proceedings of the 2003 ACM/IEEE conference on Supercomputing, 2003
Distributing data is a fundamental problem in implementing efficient distributed-memory parallel programs. The problem becomes more difficult in environments where the participating nodes are not dedicated to a parallel application. We are investigating the data distribution problem in non dedicated environments in the context of explicit message ...

Parallel Processing Letters, 2011
Petascale parallel computers with more than a million processing cores are expected to be available in a couple of years. Although MPI is the dominant programming interface today for large-scale systems that at the highest end already have close to 300,000 processors, a challenging question to both researchers and users is whether MPI will scale to ...

2008 Eighth IEEE International Symposium on Cluster Computing and the Grid (CCGRID), 2008
Institutional grids consist of the aggregation of clusters belonging to different administrative domains to build a single parallel machine. To run an MPI application over an institutional grid, one has to address many challenges. One of the first problems to solve is the connectivity of the different nodes not belonging to the same administrative ...
